几种化学药剂对小麦生态雄性不育系ES-10异交结实率的影响

Effects of Several Chemicals on Cross ollination Seed Sets of Ecological Male Sterile Line ES 10 in Wheat

本文就一些化学物质对生态不育小麦 ES-1 0异交结实率的影响进行了初步研究 ,结果表明 :化学药剂 CSC3、CSC4、CSC5、CSC6、CSC7能极显著地提高 ES-1 0× 83 -2的结实率 ,其中以 CSC4的效果最好 ,较对照的异交结实率提高 1 2 .57个百分点。

Several chemicals were used to study their effects on cross pollination seed sets of ecological sterile wheat ES 10.The main results were as follows: such chemicals as CSC3、CSC4、CSC5、CSC6、CSC7 could significantly increase the cross polination seed sets of ES 10×83 2, of which CSC4 produced a 12.5% increase comparing to the control and become the best one. The start heading stage is the optimal stage for spraying the chemicals.
