通过1986~1988年三年对杀雄剂1号和杀雄剂2号在水稻杀雄、制种上效应的研究,得出以下结果:(1)在水稻花粉充实期喷施0.015~0.02%的杀雄剂1号,能使87个参试品种的平均自交结实率降到0.7~3.3%,有72%的品种达到化杀制种要求;(2)两种杀雄剂的田间化杀制种效果无显著差异;(3)现有杀雄剂和施用方法不能克服化杀制种中产量与种子纯度呈显著负相关(r=-0.61,P<0.01)的矛盾;(4)~(32)P示踪试验揭示出杀雄剂在诱导水稻产生生理性雄性不育的同时,亦严重干扰了雌性器官的磷代谢,导致雌蕊受精结实能力降低;(5)影响水稻化学杀雄制种的主要限制因素是现有杀雄剂对雄、雌蕊的生理损伤缺乏选择性所致。
Through the research on the effects of Kao Xiong 1 and Kao Xiong 2 on killing male and seed in rice in 1986 ~ 1988, the following results were obtained: (1) spraying 0.015 ~ 0.02% Of Kaohsiung No. 1 could reduce the average selfing rate of 87 tested varieties to 0.7 ~ 3.3%, and 72% of the varieties met the requirement of killing species. (2) The field of two kinds of killing agents (3) There is a significant negative correlation (r = -0.61, P <0.01) between the yield and the purity of the seed in the Killing species and the application method; (4) The ~ (32) P tracer test revealed that the killing agent could seriously inactivate the phosphorus metabolism of female organs while inducing physiological male sterility in rice, leading to the decrease of the ability of fertilizing and pistilizing. (5) The main limiting factor for seed production is the lack of selectivity of the existing killing agents for physiological damage to the male and female pistils.
