‘巨峰’葡萄开花前 2周用氨基乙氧基乙烯甘氨酸 (2 aminoethxyvinlglycine ,AVG)10 0mg·L- 1处理可以明显增加有核果粒率和种子数。人工授粉 2 4h后 ,子房中的花粉管伸长快于对照 ,花粉管生长状况也优于对照。这是由于AVG处理降低了雌蕊中阻碍花粉管伸长物质的活性 ,同时可以改善胚囊发育 ,提高正常胚囊率和增加子房中的胚珠数和心皮数 ,这可能为促进受精和增加受精机会创造了条件
Two weeks before the flowering of ’Kyoho’ grapes, treatment with 100 mg · L -1 of aminoethoxyvinlglycine (AVG) significantly increased the number of seeds and the number of seeds. After artificial pollination for 24 hours, the pollen tubes in ovary grew faster than the control, and the pollen tube grew better than the control. This is due to the fact that AVG treatment reduces the activity of the pistil that blocks the pollen tube elongating substance while improving embryo sac development, raising the normal embryo sac rate and increasing the number of ovules and carpels in the ovary, which may be the result of fertilization and increase Fertilization opportunities to create the conditions
