ジャーナル フリーBlood groups and serum types in 508 random mongrel Japanese dogs (Canis Familiaris var japoriicers Temminck & Schlegel) were studied serologically for the purpose of applying to the pedigree registration. Five different typical specific antigens were demonstrated in the blood corpuscles by two dissimilar immune anti-serums, and were called C1, C2, D1, D2, and D1D2 respectively in the order of their demonstration. The frequency of blood groups were shown in the table 2, 3, and table 4. A naturally occurring heterohaemagglutination (a', b') with human blood corpuscles were found in dog sera correspond to anti-A, anti-B haemagglutination in normal human serums. Therefore, four different types were demonstrated in dog sera and were called O', a', b' and a', b' in the order of their demonstration, and the a' type sera showed a strong agglutination reaction with human blood corpuscules, but b' type sera showed a weak reaction.抄録全体を表示PDF形式でダウンロード (1334K) -

ジャーナル フリー7 crosses was applied to study on the inheritance of Ear-SCab in wheat plants which attacks the kernel and segregation ratios obtained was as follows ;From these results, the inheritance of Ear-SCab resistance was proved to be 3 factors in the generation of both F2 seed and F2 plant. The method of testing of Ear-SCab resistance is that : infected percentage was decided by the percentage of the spike or kernel attacked by fungus to the total ones per plant. Healthy kernels contain the healthy and imcompletely healthy ones which developed by the effect of the infection.抄録全体を表示PDF形式でダウンロード (1147K) -

ジャーナル フリーThis paper deals with the karyotypes of 3 varieties and 4 cultivated forms of Narcissus Tazetta L. l. The names and the karyotypes of those materials are as follows : Narcissus Tazetta var. papyraceus 2. The somatic chromosome complement of the variety papyraceus or "White Peal" is divided into 2 haploid sets which are quite similar to each other, and that of the varieties suisele, plena or "Grand Soleil d'Or" into 3 quite similar sets if the number of satellite is left out of consideration. 3. Comparing morphologically the ll chromosomes in the haploid set of the variety papyraceus or"Whi te Pearl" with the 10 chromosomes in one set of the varieties suisen, plena or "Grand Soleil d'Or", we can scarcely recognize a concise connection."between both the chromosome complements. It is, therefore, preferable to allaw lOand 11 as the basic chromosome numbers of N. Tazetta, 4. The chromosome complement of "Sicily White" (?) c6nsists of one chromosome set of 11-basic plant and one set of 10-basic plant, and that of "Luna" two sets of 11-basic plant and one set of 10-basic plant.抄録全体を表示PDF形式でダウンロード (565K) -

ジャーナル フリー1. In order to gain information on artificially induced translocations in rice, dormant seeds, germinating seeds and panicles just before blossoming of two varieties were X-rayed. More than two hundreds strains thus obtained were observed from the second to the fifth generations after the treatment with regard to fcrtility and other characters. 2. In a greater part of strains, fertile and semisterile plants were found in approximately I : I ratio, while in sorne other strains, either fertile or semisterile plants were predominant : in a few strains. the fertility variation seemed to be continuous. In strains segregating into fertile and semi-sterile plants, the fcrmer produced no sterile plant in their offspring, while the latter continued segregation. In strains showing continuous variation, the progeny of semi-sterile plants generally showed a similar continuous variation.抄録全体を表示PDF形式でダウンロード (788K) -

ジャーナル フリー( 1 ) The sponge gourd, Luffa, are cultivated in Japan for the purpcse of dried fibers of mature fruits, widely used for industrial purposes; for instance, to make oil-filters in certin machine, dish cleaners, certain summer hat etc. The region near Hamamatsu citv., produced the greater part of these fibre in Japan. But recently, the sponge gourd cultivation is becoming ver.v unstable due to Fusarium wilt disease, and therefore we undertook the breeding works to induce certain wilt-resistant varieties, since several years ago. In the series of the breeding wark, we adapted polyplaidy breeding paralleled to many other methcds. Although the researches and the data are somewhat defective in certain points, as this wcrk was undertaken in the course of practical breeding work, we have attained some conclusion. This paper is offered to discuss this research of polyploidy breeding. ( 2 ) The tetraploids were induced by means of colchicin treatment in 1952. Their morphological charactor and fertility were investigated for two years in non-infected field at Shizuoka city, and the wilt resistance of them were examined in the second year in the infected field near Hamamatsu city where the Fusariun4 wilt was broken cut and about 50 percent of spange gourd were darnaged.抄録全体を表示PDF形式でダウンロード (1697K) -

ジャーナル フリーDormant seeds of Nicotialca sylvestris (n=12) and N. tabacum (n=24, Bright Yellow and Dixie Bright 101) were subjected to X-ray treatments. In the first experiment (1950), the seeds of Bright Yellow were exposed to unfiltered radiation at 90 KVP, 3 mA, 15cm, of intensity of 216r/min for 10-60 minutes. The dosage applied ranged from 2, 160 to 12, 960 r units. There were no striking differences in. the germination rate of seeds or in morphological characters of mature plants between untreated and variously irradiated plants. I. n the second experiment (1951-1953), the seeds of N. sylvestris and N. tabaculee were irradiated with harder X-rays at 180 KVP, 3 mA, without filter. The dosage was 5, 000-50, 000r. At more than 15, 000r the irradiated seeds of N. sylvestris did not germljnate at all, and at 15, 000 r the germination rate was markedly reduced. Among N. tabacum varieties, Bright Yellow showed a higher tolerance against Xrays than Dixie Bright 101. The higher the dosage above 15. 000r the more delayed and uneven was the germination of treated seeds, as well as the growth of the seedlings. At the highest dosage, the germ-ination rate of the seeds was reduced, especially in Dixie Bright 101 (cf. Tab. 3).抄録全体を表示PDF形式でダウンロード (1098K) -

ジャーナル フリーChrornosome number was determined from the three species of Digit(zria. The results are summarized in Tab.1. From the results hitherto obtained it can be properly assumed that a polyploid series, diploid, tetraploid and hexaploid are existent and the basic chromosome number may be 9. As the chromosome behaviour in meiosis of PMCS was quite normal and three species possess distinct character istics, morphological and ecological (Tab. 2), authors suppose that allopolyploidy may be possible more in Digitaria.抄録全体を表示PDF形式でダウンロード (377K) -

ジャーナル フリーMiscalcthus sileelesis ANDERSS. var. coudelcsatus HACK, collected at Misaki and Inatori, and M. ti, ectorius (STEUD.) HACK. collected in Gifu and Shiga Pref. were found to be diploid, the chromosome number observed being 1c='19, 2n=38. With regard to M. tiinctorius. TAKIZAWA had previously found tetraploid and hexaploid plants Therefore, the discovery of diploid implies the establishment of a complete polyploid series. Moreover, M. tinctorius seems to be different in geographical distribution with polyploidy. It was observed in M. sin;ensis, Ie=19, 2 Ie=38, the same chromosome number as TAKIZAWA'S result. But in the present experiment, aneuploid was not observed which TAKIZAWA had found.抄録全体を表示PDF形式でダウンロード (641K) -

ジャーナル フリー1. Cross-compatibility in three cultivated cucurbita species varies when crossed reciprocally. In order to study the cause of this phenomenon, the authors attempted to investigate the physiology of pollen germination on the artificial media and the influence of stigmata or ovules of different species upon polleh germination. 2. The optimum condition of artificial media for pollen germination varies with different pollen ages during the period from the afternoon of the day before anthesis to the noon of flowering day. 3. Pollen germination increases as pollen maturates. The optimum pH for pollen germination undergoes the following change : weak acid-weak alkali-weak acid-acid. 4. The gtowth rate of pollen-tubes is classified into twelve groups according to the mixing ratio of short, middle and long pollen-tubes. 5. The viability index of pollen has been obtained from the following fcrmula : (Germination rate of pollen) x (Growth rate of pollen-tubes) x 1/100. 6. The highest viability index of pollen by the pH experiment of C. maxima has been observed at pH 5.6 of 2 a.m. (Table 3). 7. The optimum saccharose concentrations of artificial media changes with different pollen ages from high to low percentages (Table 4, 5 and 6).抄録全体を表示PDF形式でダウンロード (1229K) -

ジャーナル フリーIt is commonly known already a strain of the crested double flowering cosmos produces 0 to 60% double flowering plants in its seedlings usually. These crested-double flowers, however, are not always of perfectly fine full-doubled (DDD-typed, signed temporarily) but of imperfect serni-(DD-typed) or slightly-doubled (D-typed) in some considerable d'efinite ratio. Furthermore, in a few cases come out the ball-shaped or aster-1ike double flowers (DDDD- typed) on the slender and much branched plants, alike some plants with the fluted (F-typed), tubulared single (T-typed) or non-petaled (N-typed) flowers. Seeds obtained from the full-doubled DDD-mother plants pollinated artificially with slightly-doubled (D) pollen segregate about 68%: double flowering., and those fertilized naturally (possibly with many pollen of single-flowering (S) and partly of slightly-doubled (D-DD)) produce about ' 50 or more % of doubleflowering seedlings in the next generation. And seeds from the imperfect semi- or slightly.-doubled plants pollinated naturally give only 14 to 47% (in 1953-!54) of double flowerin.g. Still more, it is observed freqtiently that the fluted doubled and tubulared singled flowers are found in the seedlings derived from the normal cresed doubled plants.抄録全体を表示PDF形式でダウンロード (1279K)
