通过对四个水稻品种(Ratna、Jaya,Masuri和Kaioijra)从喂饲叶(源)向其它叶片(库)输出的分析表明,在籽粒形成期~(32)P从源叶向库叶输出具有相邻关系的功能。但在籽粒发育期,无论什么品种,倒三叶不保持这种关系。在所有叶片中,倒三叶中的~(32)P输向籽粒最少。品种Radna和Jaya在籽粒发育期,~(32)P从旗叶输向籽粒和茎杆最多。而品种Masuri和Kaloina在籽粒形成期,~(32)P从倒二叶输出最多,而不是在符粒发育期,从旗叶输出。本研究产生了这样一个事实,虽然~(32)P的使用量一改,但喂饲叶的相对输出,因品种而异,不同的水稻品种诱导叶片衰老的方式(顺序和排顺序的)也不同。
The analysis of the output of four rice cultivars (Ratna, Jaya, Masuri and Kaioijra) from the feed leaves (source) to other leaves (stocks) showed that at the grain formation stage, Functions of adjacent relations. However, in the grain development, no matter what species, inverted clover does not maintain this relationship. Among all the leaves, ~ (32) P in the third leaves was the least translocated to the grain. Varieties Radna and Jaya lost most of the translocation of ~ (32) P from the flag leaf to the grain and stem at the grain development stage. However, the cultivars Masuri and Kaloina showed the highest output of ~ (32) P from the second leaf during grain formation, rather than from the flag leaf during the development of the grain. The present study led to the fact that although the amount of ~ (32) P used was changed, the relative output of the feed leaves varies with the variety and the way in which different rice varieties induce leaf senescence (in order and in sequence) also different.
