Bergamot was introduced into and cultivated in the district of the Seto Inland Sea (Ehime and Kagawa prefectures) in 1963 from Shizuoka prefecture, and it began to bear its fruits in said district in 1967.
The present study is to examine the percentage of oil and the chemical composition of the oil obtained from the plant in said district.
The bergamot oil is contained in the oil sacs in the pericarps of the plant. The percentage of oil was found to be 0.38% by means of compression method. The result of the analysis by gaschromatography of the oil showed d-limonene 26%, l-linalool 29% and linalyl acetate 29%, and was almost similar to the oil from the plant grown in Calabria in its quallty.
As to climatic condition, damage due to frost in the winter season is especially a problem, but in view of the tried planting of the plant up to the present time, it is thought that from the standpoint of locality and climatic condition the south-west district of Japan will be possible to cultivate the bergamot if proper district is selected.

This experiment was practiced concerning plant development, dry matter and the changes of cotyledonary tissues, especially the consumption of the stored foods in the seeds of peanut (variety Southern Cross) during germination. Plant developments are denoted in Figs. 1-2, transitions of dry matter in Fig. 3, changes of external shape and water contents of cotyledons in Figs. 4-5. As shown in Figs. 6-7 and Tabs. 1-2, the stored foods of cotyledons begin to be digested from the part of tissues among the vascular bundles, being remained around the part of them till late. Protein was exhausted more rapidly than starch and lipids. Intensity of Iodine reaction in Age 2 was superior to that in Age 1. Therefore it may be supposed that protein covers starch grains in Age 1, whereas it is removed in Age 2, so that Iodine reaction became clear.

1) This experiment aims to make clear the heading characteristics of japonica rice varieties under different sowing time at Ceylon. This experiment was conducted at the Central Agricultural Research Institute, Peradeniya, Ceylon in 1965.
2) Sixteen varieties were sown at about one month interval in cement pots. These varieties consisted of 10 Japanese paddy varieties, 2 Japanese upland varieties, 2 Taiwan varieties (Ponlai) and 2 Ceylon short duration varieties. Heading date and number of leaves on the main stem was recorded.
3) The heading time of japonica varieties were controlled almost exclusively by their basic vegetative growth period, because the variation of temperature was very small and the photosensitivity was digested due to the natural daylength shorter than the critical daylength of optimum region of them. It is considered that the basic vegetative growth of Japanese paddy varieties were too short to get high yield.
4) There is difference between Japanese paddy varieties and others about the relationship between number of days from sowing to heading and number of leaves on the main stem. The leaf emergence intervals of Japanese paddy varieties are smaller than those of other varieties. If there is any difference of growth habit between Japanese paddy varieties and others, this may be interesting.

Quantitative analyses of plant growth substances in lateral buds of sugar cane, variety N: CO 310, were carried out, using the avena straight growth test method.
1) Before planting shoots of sugar cane were immersed in water and limewater. The growth inhibitor, on Rf value of 0.9-1.0 in each treatment, decreased, while in comparison with that of intact shoots no increase was observed in the growth promoters.
2) The date of sprout initiation after planting was promoted by the two previous treatments done in vaccum and natural room condition for 8 days. However a higher rate of sprout was found in the latter treatment. In both cases, the growth inhibitor, on Rf value 0.9-1.0 was more decreased than in that of intact shoots, while it was only in the latter treatment that the growth promoters on Rf value 0.7-0.9 showed a marked increase.
3) From the results of the experiments, it was assumed that the promotion of lateral buds sprouting is to be strongly influenced by the decrease of the growth inhibitor and by the increase of the growth promoters.
