研究了蛋氨酸和多效唑对杂交水稻抗倒性及产量的影响。蛋氨酸能明显缩短植株基部 3个节间长度而增强抗倒性 ,增产效果较明显 ;多效唑主要抑制植株上部节间的伸长 ,且造成生育期延长 ,增产不明显
The effects of methionine and paclobutrazol on lodging resistance and yield of hybrid rice were studied. Methionine significantly shortened the length of the internode at the three internodes and enhanced the lodging resistance, and the effect of increasing yield was obvious. Paclobutrazol mainly inhibited the elongation of the upper internode and resulted in the prolongation of growth period with no significant increase in yield
