“杀雄剂一号”的主要成份为甲基胂酸锌(CH_3AsO_3Zn·H_2O)。在水稻花粉内容物充实期喷洒后,通过植株吸收,CH~3AsO_3H_2能迅速转运到穗部,使雄蕊发育过程中的正常呼吸代谢受到破坏,能量代谢发生障碍,花粉丧失萌发力或花粉管不能伸长,导致非遗传性雄性不育的产生,杀雄效果可以达到95—100％。 The main component of “killing agent No. 1” is zinc methylarsenate (CH_3AsO_3Zn · H_2O). After the pollen contents of rice are sprayed through the plants, the CH 3 AsO 3 H 2 can be quickly transported to the ear through the absorption of the plant, the normal respiratory metabolism during stamen development is damaged, the energy metabolism is impaired, the germination force of the pollen is lost or the pollen tube can not extend Long, resulting in the generation of non-genetic male sterility, killing effect can reach 95-100%.
