From the experimental results, it is evident within the seeding date in this experiment that the height and the haulm yield of March 10 seeding-made in at the max. in Shanghai district. Seeding was not done before March 10 in this experiment, therefore it is not easy to make sure of the results originated from the seeding at the end of Feb. or March 1. However, from the result made under such seeding date as previously in 1942 it is evident that seeding to germination takes longer because of lower temperature and then is not uniform in germination or in growth. Since when cultivating flax by making use of the paddy field open for rice-planting, the seediug dace on about March 10 seems to be right in Shanghai district. Of seeding made after March 20, may conclude that the height-extent be likely not to be enough and the yield seems not to be adequate. In case cultivating flax in the paddy rice field, the stem grows shorter (not well advanced in growth), the yield less in Shanghai district than other fields. But from the viewpoint of fiber production, to make use of thc empty space open for rice-planting, which had not been, conceivable by the time, and yet capable of yielding pretty well, ought to be remarkable. It is unavoidable in this district that the quality bacomes worse through changeable temperature than other flax-fields as Germany, France, Belgium or etc. But, those in Shanghai district, as compared with Hokkaido's, Manchuria's, show not so many differences in those fibrous tissues; which are, for instance, the total number of fibrous cells per on bundle or the diameter of fibrous cell or the thickness of fibrous cell wall, etc. That the amount of fibrous bundle of flax grown in Shanghai district is extremely numerous than of Hokkaido or Manchuria-grown, is quite favorable. But, as regards to this cause for it, we must look to the future study.
