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
