摘要: ‘巨峰’葡萄开花前2 周用氨基乙氧基乙烯甘氨酸( 2-aminoethxyvinlglycine, AVG)
100 mg!L-1处理可以明显增加有核果粒率和种子数。人工授粉24 h 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。

Abstract: The AVG ( 2-aminoethoxyvinylglycine) 100 mg!L-1 application enhanced the rate of seeded berries percluster and number of seeds per berry. Water soluble growth inhibitors of pollen tube in the pistils decreased significantly
after AVG treatment, in comparison with the untreated control, which may induce a decrease of the pollen tube growth in pistils of control, and so that no tube reached the micropyles of ovaries of control whthin 24 hour after pollination. AVG treatment also increased the rate of normal embryo sac and numbers of carpel of ovules per ovary.

Key words: Grapevine, AVG ( 2-aminoethoxyvinlglycine), Pollen tube, Carpel, Ovule
