摘要
研究授粉处理对"度尾文旦"[Citrusgrandis(L.)Osbeck.cv.Duweiwendan]柚果实发育期间内源赤霉素(GA3)、脱落酸(ABA)、生长素(IAA)和玉米素核苷(ZR)的影响。结果表明:"度柚6号"和"琯溪蜜柚"授粉对"度尾文旦"柚果皮内源激素含量的影响大致类似;授粉处理增加了授粉后30～60d及授粉后90～120d的ABA含量;授粉处理增加了"度尾文旦"柚果实细胞分裂初期和授粉后60～130d的GA3含量;授粉处理降低了授粉后40～90d的ZR含量,增加了授粉后90～140d的ZR含量;授粉处理降低了"度尾文旦"柚整个果实发育过程中果皮的IAA含量;授粉处理增加了"度尾文旦"柚果实发育期间尤其是授粉后90～140d的ABA/(ZR+IAA+GA3)的比值。
The effect of pollination on the contents of endogenous hormones in the Pericarp of Duweiwendan Pomelo （Citrus grandis L.） was studied. The results showed that the pericarp of Guanxi-pollinated and Duyou Ⅵ-pollinated fruits had a higher ABA content during 30-60 days after anthesis （DAA） and a higher GA3 content during 60-130 DAA as compared with the non-polllnated control. The ZR content in both treatments was reduced during 40-90 DAA but increased to a higher level as compared to the control during 90-140 DAA. Pollination decreased IAA content throughout fruit development but increased the（IAA＋ZR＋GA3）/ABA ratio during 90N 140 DAA.
