ＧＡ３和ＢＡ具有打破假高粱籽实休眠的作用。在２５／３５℃、１６／８小时和光、暗各１２小时条件下，对于剥去颖片的籽实，ＧＡ３以浓度为３５０×１０－６的效果最为显著，随激素浓度的升高或降低，籽实的萌发率呈下降趋势。ＢＡ以２００×１０－６浓度效果最为明显，但作用效果不及ＧＡ３。文中讨论了激素促进杂草籽实萌发在植物检疫工作中的意义 GA3 and BA have the effect of breaking dormancy of fake sorghum seeds. Under the conditions of 25/35 ℃, 16/8 hours and light and dark for 12 hours, the effect of GA3 on the stripping of glume seeds was the most significant at the concentration of 350 × 10-6. With the increase or decrease of hormone concentration, Seed germination rate showed a downward trend. BA concentration of 200 × 10-6 most obvious effect, but the effect is less than GA3. This paper discusses the significance of hormones to promote the germination of weed seeds in plant quarantine
