摘要

The variety of rape, Norin No. 5 (Brassica napus) was used for the study on the rate of development of seeds, pods and oil. Plants were grown on pots in a glass-house after seedling period in seed-bed. Each pod was tagged at the flowering time and samples Collected at 5 days intervals during the period of seed development. Length and width of pods or seeds grew rapidly during the early period of seed development, and reached a maximum size at 25∼30 days after flowering time. Increase of dry and green weight of pods indicated the maximum at 40 days after flowering time, but weight of seeds continued to increase until 55 days after flowering time. Oil percentage of seeds (based on dry weight) ceased to increase before dry weight of seeds reached the maximum. But the total weight of oil per 1000 dry seeds indicated the continuous increase until the dry weight of seeds reached the maximum. The iodine value and refractive index of extracted oil decreased as the seed developed, and began to increase after total oil deposited.
