JOURNAL FREE ACCESSEffects of the amount of fertilizer [N, P2O5 and K2O at 0 (Non-F), 6 (L), 12 (M) and 18 g (H) m-2, respectively], and the kind of fertilizer [conventional fertilizer (CF) and the compound fertilizer containing slow-release fertilizer(SRF, Kumiai-Hifuku Nyoso Iri-Fukugo 444E-80)] on the nitrogen absorption from 23-27 days before heading(EYPF)to heading and bleeding rate from the cut-stem end at meiosis and full heading stages were examined in a Chinese high-yielding indica cultivar, Yangdao 4, in comparison with a Japanese cultivar, Hinohikari. The number of productive stems having four or more leaves per stem increased with increasing amount of applied fertilizer and the ratio of increase was higher in the SRF plot than in the CF plot in both cultivars. The number of productive stems was 1.6-2.3 times higher in Hinohikari than in Yangdao 4 with the same amount of applied fertilizer, while the stem weight was 1.9-2.5 times higher in Yangdao 4 than in Hinohikari. The bleeding rates per hill in CF and SRF plots were higher in Yangdao 4 than in Hinohikari except L-SRF plot at the full heading stage, although it was lower in Yangdao 4 in the Non-F plot. The bleeding rate increased with increasing amount of applied fertilizer in CF and SRF plots in both cultivars, but no significant differences were observed between CF and SRF plots with the same amount of applied fertilizer, and the ratio of increase was higher in Yangdao 4 than in Hinohikari. The average bleeding rate at the both meiosis and full heading stages was closely correlated with the average number of productive stems and the average bleeding rate per stem in Yangdao 4 and the correlation coefficient with the latter was higher than that with the former. In Hinohikari, however, the bleeding rate was closely correlated only with the number of productive stems. The average bleeding rates per hill and per stem were closely related with the amount of nitrogen absorption per hill and per stem during the period 23-27 days before heading, respectively. From the results, it was concluded that Yangdao 4 showed a higher bleeding rate and nitrogen absorption rate per hill than Hinohikari, due to the higher bleeding rate per stem.View full abstractDownload PDF (952K) -

JOURNAL FREE ACCESSCool weather is a serious climatic constraint for rice cultivation in hilly and mountainous regions. Deep-flood irrigation is known as the most effective method to protect rice plants from cool weather damage. Therefore, we examined its effects on the growth and yield characteristics of rice in hilly and mountainous regions. Three water management regimes were designed: DF-I (deep-flood irrigation from rooting stage to heading), DF-II(deep-flood irrigation from just before maximum tiller number stage to heading), and CWM (conventional water management). In 1999 and 2000, the maximum tiller number per m2 in the DF-I plot was smaller than those in the CWM plot. In contrast, the maximum tiller number per m2 in the DF-II plot was comparable to that in the CWM plot in both years. The panicle number per m2 in the DF-I plot was significantly lower than that in the DF-II plot in 1999 and the CWM plot in 2000. The rice yield in the DF-I plot was significantly lower than that in the CWM plot in 2000. However, the yield in the DF-II plot was the same as that in the CWM plot in both years. We conclude from these results that deep-flood irrigation from just before the maximum tiller number stage to heading is the most effective water management regime for avoiding cool weather damage and obtaining a stable rice yield in hilly and mountainous regions.View full abstractDownload PDF (891K) -

JOURNAL FREE ACCESSField trials were conducted to examine the growth and yield characteristics of rice (Oryza sativa L.) cultivated in deep-flood irrigation under no-tillage cultivation with single basal fertilization to the nursery box in hilly and mountainous regions, where low temperatures often cause cool weather damage and where labor-saving and low-cost cultivation is also required. Three water management regimes were designed: DF-I (deep-flood irrigation from early growth stage to heading), DF-II (deep-flood irrigation from productive tiller stage to heading), and CWM (conventional water management). The maximum tiller number and panicle number per m2 in the DF-I plot were smaller than those in the CWM and DF-II plots in 1999. In contrast, panicle number per m2 in the DF-II plot was comparable to those in the CWM plot in both years. Panicle number per m2 positively and significantly correlated with grain yield in 2000. The percentage of grain filling was significantly improved by DF. No significant differences in rice yields were observed among the water management regimes in both years. Nitrogen recovery of the fertilizer by rice was not significantly affected by the water management regime, whereas the no-tillage plot showed higher nitrogen recoveries of the fertilizer than those of the tillage plot. Considering the results, we suggest that DW-II with no-tillage cultivation is effective for both avoiding cool weather damage and for developing low-cost and labor-saving rice culture in hilly and mountainous regions.View full abstractDownload PDF (1232K) -

JOURNAL FREE ACCESSReduction of low-level Cadmium contamination in brown rice was examined under three nitrogen fertilization conditions: application of methane-fermented manure liquid (MF), application of ammonium sulfate fertilizer (CF) and no nitrogen fertilization (NF). Rice was grown in the pots with gray lowland soil and andosol amended with cadmium (Cd) at the concentration of 2 and 5 ppm, respectively, and fertilized as above. Several parameters including soil redox potential (Eh), amount of Cd absorbed by rice plants and its partition to brown rice, were periodically determined during the growth. In both gray lowland soil and andosol, soil Eh was significantly lower in MF than in CF and NF during the growth period from panicle initiation to heading, and Cd absorption by rice plants and Cd allocation to brown rice were also lower in MF than in CF and NF. Split application of MF resulted in a lower Cd concentration in brown rice than basal application without reducing brown rice weight. These results suggested that applying MF, in both kinds of soil, reduces the low-level Cd contamination in brown rice.View full abstractDownload PDF (1009K) -

JOURNAL FREE ACCESSWheat yellow mosaic is a soil-borne virus disease, and has spread in recent years. The disease incidence is known to decrease by delaying the seeding time, and a high air temperature and a lot of rain after seeding result in serious damage in the spring. Thus, the effect of winter-seeding cultivation (W.S.) seeding before continuous snow cover, on the disease incidence of wheat yellow mosaic was investigated using susceptible winter wheat (cv. Nanbukomugi). In the field infested with wheat yellow mosaic virus (WYMV), the disease degree was compared in wheat plants cultivated by two cultivation methods [standard autumn-seeding cultivation (S.A.S.) seeding from early October to mid-October and W.S. (seeding from early December to mid-December)]. In S.A.S., the disease incidence and the disease severity were 100% and 99 in the field highly infestated with WYMV. In W.S., the disease incidence and the disease severity were 0—5% and 0—2, respectively, which were significantly lower than those in S.A.S.. The mean air temperature after seeding in S.A.S. was high, and the number of days with mean air temperature above 5°C which is thought to be suitable for infection of wheat with WYMV was 40 or more. On the other hand, the mean air temperature was below 5°C from seeding date to late March after snow melting in W.S.. We consider that the incidence of wheat yellow mosaic in W.S. was suppressed by low temperature after seeding. In W.S., the ear number was larger, the thousand grain weight was heavier, and the grain yield was 23—65% higher than those in S.A.S..View full abstractDownload PDF (1620K) -

JOURNAL FREE ACCESSBecause it takes more than six years from the transplanting of tea cuttings to the establishment of a mature tea field, it is desirable to shorten this period in tea production. The growth of young tea plants was proportionally enhanced by increasing the number of branches. In this study, therefore, we examined a method to increase the number of branches on tea cuttings and examined the growth after transplanting of the tea cuttings with different numbers of branches. Tea cuttings were planted in paper pots in June, grown in the nursery bed until March in the next year, and then transplanted to the tea field. The tea cuttings without pruning developed less than two branches. However, by pruning the new shoots of the tea cutting leaving five leaves on the cuttings in September, we succeeded in preparing the cuttings with more than seven branches before transplanting. The number of branches and the growth of young tea plants developed from the cuttings pruned as above were greater than those of the plants from the cuttings without pruning, resulting in a higher yield.View full abstractDownload PDF (1049K)

JOURNAL FREE ACCESSIn this study, we examined the effects of the field type, planting density, seeding time, fertilizer and soil type, on the content and composition of isoflavone in soybean seeds for three years. The total isoflavone content of 12 soybean cultivars was higher in the order of upland field with regular seeding time (UR) < drained paddy field with regular seeding time (DR) < upland field with late seeding time (UL). The ratio of highest to lowest total isoflavone content was 3.0, 2.2 and 2.3, respectively in the 12 cultivars in UR, DR and UL. Moreover, the interannual coefficient of variation in total isoflavone content tended to be increased in the order of UL (4-31%) < UR (6-27%) < DR (10-44%). No significant difference was observed in either the content or composition of isoflavone among the three planting densities ranging from 8.3 to 16.7 hills/m2 and the content was unrelated to yield in 'Suzukari' and 'Tachiyutaka'. On the other hand, the isoflavone content increased as the seeding time was delayed in 2000. The effects of the soil type and fertilizer on the contents and compositions of isoflavone, were examined using'Fukuibuki' grown at Fukushima Agricultural Experiment Station in 2001. The kuroboku soil conditions, as compared with the grey lowland soil conditions, gave high isoflavone contents, but the composition was not changed. These results suggest that soybean with constantly high isoflavone content may be produced by late-season culture at a high planting density on fertile soil.View full abstractDownload PDF (1278K) -

JOURNAL FREE ACCESSThe rapid and simple method for measuring the phyllodulcin content, which is the main component for sweetness of amacha (sweet Hydrangea) varieties, was established using HPCL. Fifty samples could be analyzed in a day by this method in contrast to 20 samples by the former method. We crossed amacha varieties and obtained many healthy seedlings by spraying them with gibberellin (50 ppm) after seeding and spraying liquid fertilizer to the young seedlings. Many seeds and F1 plants were obtained from crossings of Amacha / Amagiamacha. Fresh leaf weight per plant and the concentration and the content of phyllodulcin per plant in the F1 plants showed a normal distribution, suggesting that these traits were controlled by polygenes. In most of the F1 plant, total fresh leaf weight and phyllodulcin concentration were distributed between the values of the parents. However, in many F1 plants, phyllodulcin content per plant exceeded the values in both parents. Phyllodulcin concentration did not correlate with leaf weight. This may be why many F1 plants contained a large amount of phyllodulcin per plant than both parents. The year-to-year correlation of phyllodulcin concentration was high.View full abstractDownload PDF (789K)

JOURNAL FREE ACCESSSalt tolerance at the germination and seedling stages in 30 cultivars grown in Huabei area of China was compared with that in 30 Japanese cultivars. The result of the germination test in tap water (control) and saline water [0.2% (34 mM), 0.4% (68 mM), 0.6% (103 mM), 0.8% (137 mM) and 1.0% (171 mM) NaCl] showed no significant difference between the Chinese and Japanese cultivars. In the 5-week-old seedlings with about 7 leaves cultivated in 0.25% (34 mM) saline water for 16 days, salt tolerance of Chinese cultivars was significantly higher than that of Japanese cultivars at the seedling stage. No significant correlation was found between the salt tolerance at the germinating stage and that at the seedling stage. However, salt tolerance of two Chinese cultivars (Kenyou18 and Jindao206) was strong both at the germinating and seedling stages. In Japanese cultivars, Akigeshiki, Aikoku and Fujihikari showed high salt tolerance only at the seedling stage. These results suggested that these cultivars would be useful materials for salt-tolerance breeding in Huabei area.View full abstractDownload PDF (872K) -

JOURNAL FREE ACCESSThe varietal difference of the yield components and pearling quality in four varieties used as pearled barley in the Hokuriku region were analyzed for five years, to breed new varieties that stably exhibit superior traits. There were no significant genotype × year interactions in the number of panicles, 1000-grain weight, plump-grain rate, crude protein content, steely-grain rate and rigidity value. Significant interactions were detected in plump-grain yield, 1-liter-grain weight, pearl whiteness, and pearling time. ‘Minorimugi’ had high plump-grain yield in the years suitable for barley growth, but markedly low plump-grain yield in the years with much snow or rain at the ripening stage. ‘Hokuriku kawa 35’ was the most stable variety in yield. Varieties with the heaviest or lightest 1-liter-grain weight varied with the year. ‘Shunrai’ was the most stable variety in pearling quality. The pearl whiteness was the lowest and pearling time was the longest in ‘Minorimugi’ every year. We suggest that the annual variations of plump-grain yield, 1-liter-grain weight, and pearling quality were mainly caused by precipitation during the ripening stage, and that the effects of environmental factors varied with the variety. It is necessary to examine these traits for several years including the years with undesirable conditions to breed fine varieties stably. The rate of infection with scald varied with the year, but even susceptible varieties did not show the symptom every year under ordinary cultivation conditions.View full abstractDownload PDF (1083K) -

JOURNAL FREE ACCESSForty-three soybean cultivars released from 1915 to 2001 in the western region of Japan were divided into three groups, I, II and III, by the released year and evaluated for their characteristics. Old cultivars included in groups I and II had great diversities in some characteristics, but new cultivars included in group III had decreased diversity. Flower color and pubescence color were unified to purple and grey, respectively in group III. Groups I and II contained nearly the same number of early, medium and late maturing cultivars, but almost all cultivars showed medium maturity in groupIII, because cultivars with intermediate maturing type were widespread in this period. The seed-filling period of cultivars in group III was longer compared with that in groups I and II, which was considered to be advantageous for high yield. Plant height and the number of nodes were decreased in group III, which contributed to the improvement of lodging resistance significantly. However, the yield advantage was not found in the cultivars of group III compared with the cultivars of groups I and II. The decrease in the number of nodes was associated with the decrease in pod number, so the seed yield of the new cultivars was not increased though 100-seed weight increased. Although the new cultivars, ‘Tamahomare’ and ‘Sachiyutaka’ had shorter stems and fewer nodes than cultivars of groups I and II, they had a seed yield as high as that of high-yielding late maturing cultivars. The seed quality such as protein content was consistently improved in newly released cultivars.View full abstractDownload PDF (1052K) -

JOURNAL FREE ACCESSThe morphology, yield and grain quality of Tartary buckwheat were evaluated in the field in the Kyushu and Kanto areas for two years, and the difference from those of common buckwheat was discussed. The range of year-to-year variation of the morphological characters, such as plant height, main stem length, number of nodes and number of primary branches were slight, but that of productivity, such as total weight and grain yield were large. However, these characters varied with the variety, and the order of the values of each character was the same in both years. Consequently, it seemed that these characters are useful as the indicators of varietal characteristics. Furthermore, it was indicated that the varieties with a large size and high growing capacities are advantageous to obtain high grain yield. It was also indicated that the response of these characters to sowing time varied with the variety. The rutin content of Tartary buckwheat grains was more the 100-fold that of common buckwheat, while the antioxidative activity of Tartary buckwheat grains was about 3-4 fold that of common buckwheat. It was suggested that Tartary buckwheat differs from common buckwheat in the content of antioxidative compounds.View full abstractDownload PDF (1106K) -

JOURNAL FREE ACCESSRecovery of dry-matter production after drought stress is an important factor of drought resistance in plants. Napiergrass, whose dry matter weight largely decreased by soil drought treatment, increased dry-matter weight vigorously under the well-watered soil condition. In this study, the changes in total dry-matter weight (TDW), leaf area (LA) and photosynthetic rate (Pn) in napiergrass during and after the soil drought treatment were compared with those in maize grown in the same pots to clarify whether TDW of napiergrass quickly recovered after the soil drought treatment. In maize plants, TDW and LA during six days soil drought were as high as those in the control plants. Plant growth rate (PGR), relative growth rate (RGR) and net assimilation rate (NAR) under soil drought treatment remained as high as those in the control plants, but decreased to approximately 50% of that in the control plants after re-watering. In napiergrass, on the other hand, TDW and LA decreased under six days soil drought treatment to 70% and 30%, respectively, of control. However, LA increased to 50% of that in the control plants at the 6th day after re-watering. NAR did not decrease under drought stress though PGR and RGR decreased. Pn decreased slowly under soil drought condition but recovered quickly after re-watering. The increase in TDW was slight, but LA and Pn quickly recovered within six days after drought treatment.View full abstractDownload PDF (659K)

JOURNAL FREE ACCESSTo analyze the cultivar differences of nitrogen fixation capacity in soybean under a high soil nitrogen condition, we estimated the amount of nitrogen fixed during the growing season and the percentage of the amount of fixed nitrogen against the total accumulated nitrogen (RU-%Ndfa) by the relative ureide method,using eight genotypes including six common cultivars, a supernodulation cultivar and a non-nodulation line. Supernodulating cultivar, Sakukei 4, fixed the greatest amount of nitrogen in two years. American cultivars, Williams and Lee, had smaller amount of fixed nitrogen than Japanese normal cultivars in each maturity group. Especially, the amount of fixed nitrogen in the latter half of the growing period, which had a close positive correlation with the nodule weight in the middle growing period, was smaller in the American cultivars. RU-%Ndfa had a close positive correlation with the value estimated by 15N natural abundance method (δ15N-%Ndfa). The RU-%Ndfa was the highest in Sakukei 4 among all cultivars examined. The American cultivars had lower RU-%Ndfa than the Japanese normal cultivars in each maturity group. We concluded that, under a high nitrate condition, the amount of fixed nitrogen was smaller and RU-%Ndfa was lower in the American cultivars than in the Japanese normal cultivars, and the nodule weight in the middle growing period might contribute to these cultivar differences.View full abstractDownload PDF (1126K) -

JOURNAL FREE ACCESSIn this experiment, primary leaves of two varieties of Adzuki beans, Buchishouryukei-1 which is cold sensitive in the budding stage and Akanedainagon which is cold resistant in the budding stage were used. The primary leaves were exposed to chilling in the shade (10-13°C, 72% shading) for either 28 days(28-day group) or 18 days(18-day group). In Akanedainagon, chlorophyll was synthesized under subsequent greening conditions (20-25°C, sunlight), even in the 28-day group though more slowly than in the 18-day group, and no plants in the 28-day group died. In contrast, in Buchishouryukei-1, the greening treatment did not lead to chlorophyll synthesis in the primary leaves in the 28-day group; moreover, the death rate was about 20% before the greening treatment and it further increased thereafter. In primary leaves of Buchishouryukei-1, H2O2 content and superoxide dismutase (SOD) activity were markedly higher in the 28-day group than in the 18-day group, and SOD, ascorbate peroxidase and catalase activities in the 28-day group were markedly decreased by greening treatment. On the other hand, in the primary leaves of Akanedainagon, only a slight increase in H2O2 content and SOD activity, and no change in the oxidation-inhibiting enzymes were observed in the 28-day group. Long-term (28-days) chilling and shading were found to cause H2O2 accumulation in the primary leaves of Buchishouryukei-1. The difference between the two varieties in the cold resistance of primary leaves could be attributed to the difference in the O2- formation brought about by the chilling and shading treatment.View full abstractDownload PDF (736K)

JOURNAL FREE ACCESSThis study was conducted to examine the effect of autumn puddling before wheat seeding and application of controlled-release fertilizer on the growth of rice direct-seeded in the wheat stand. Yield and quality of both rice and wheat were evaluated. Three kinds of controlled-release coated urea, LPS100, LPSS100 and LPS120, were applied at a 5 cm depth to a V-shape furrow at the time of rice direct seeding. Judging from the nitrogen release pattern and rice growth, LPSS100 was the most suitable for basal application, and LPS120 was suitable for top dressing at ear-formation stage of rice. None of the coated urea influenced yield and quality of wheat. Autumn puddling before wheat seeding was very suitable for rice direct seeding in mid-February. It hardened and leveled the paddy field, and therefore, sowing depth of rice seed was very uniform and the number of established rice seedlings per unit area was higher than in the field tilled before wheat seeding. Neither the seeding machine for wheat nor the combine for rice showed any harmful effects. By using autumn puddling and basal application of coated urea LPSS100, 4.94 tons ha-1 of wheat and 5.32 tons ha-1 of rice were harvested in the 0.94 ha paddy field and labor time was reduced to 23.5 hours ha-1, in 1999. These results showed that this cultivation system was labor-saving and produced a stable yield.View full abstractDownload PDF (1441K)
