板栗自交与异交后子房内源激素含量的变化规律

In order to verify the endogenous hormone at reproductive development in chestnut, this paper using chestnut cultivar 'Yanshanzaofeng' as material from Qianxi county, regularly taking the ovaries after self- and -corss pollination. The changes of endogenous hormone in the ovary 0~50 day after pollination were determined by the HPLC. The results were showed that the ovary of selfing and outcrossing IAA, GA3, ZR and ABA endogenous hormones contents showed fluctuation trends. Outcrossing ovary IAA+GA3+ZR/ABA in chestnut were higher than selfing, while pollination and fertilization, the content of ovary ABA self-pollination was significantly higher than cross-pollination. The results could be sprayed GA3 and ZR at the pollination and fertilization stage, which provided basic information for improving chestnut production.
