From the restilts obtained so far by the authors, it is clear that the photoperiodic response in spring wheats is infiuenced by the day-length in the period during which the three leaves already formed in the embryo are eloirgating, and as long as the dark period ls not interst. itial during that poriod described above, these spring wheats convert to the reproductive growth with the minimum vegetative growth(5-6 Ieaves, being cdnstant, in different varieties). However, as the period during which the three leaves already formed in the embryo are elongating and developing corresponds also to the period receiving the effects of endosperm, it is inferred that the facts described above niay be due to the influence of differenbes of endosperm. As reported in the previous paper, there was no variation in the basic vegetative growth but some deviations were to be seen in the develbping-velocity of each leaf on the nlain culm. However, in: the experiment reported in the previous paper, the usual intact seeds not subjected to the trarisplanting treatment were used as the control, no definite conclusion couid be drawn concerning to the infiuence of differences of endosperm.
