摘要
在小麦生态雄性不育系 ES- 1 0孕穗期至抽穗期 ,喷施不同的化学药剂 ,研究其对 ES- 1 0× 83- 2制种产量的影响 .结果表明 :喷施化学药剂 CSC3,CSC4,CSC7能极显著地提高制种产量 ,单产分别比对照增加 32 3.2 5 ,34 3.80 ,1 6 3.35 kg/ hm2 .喷施 CSC8增产幅度达到显著水平 .喷施 CSC1 ,CSC2使制种产量比对照减产 498.45 ,36 8.40kg/ hm2 。
Severial chemical substances were used to study their effects on the seed yields of ecological male sterile line in wheat ES 10×83 2 during ES 10 from boot stage to heading stage . The results are as follows:Chemical substances such as CSC3, CSC4, CSC7 can increase the seed yield by 323.25, 343.80,163.35 kg per hectare respectively when compared with the untreated.The contrast reaches significant level.CSC8 can also significantly improve the yield of seed production,while CSC1,CSC2 decreases the seed yield by 498.45,368.40 kg per hectare and the decreases reaches significant level.
