摘要
研究不同浓度的ＩＡＡ对黄瓜花粉管伸长及内源ｃＡＭＰ含量的影响．结果表明：５ｍｇ／ＬＩＡＡ明显促进花粉管伸长，而１００ｍｐ／ＬＩＡＡ则完全抑制花粉萌发．用５ｍｇ／ＩＡＡ处理花粉时．在花粉管长出之前，花粉内源ｃＡＭＰ含量出现一个明显的峰值，推测ｃＡＭＰ可能对ＩＡＡ促进黄瓜花粉管生长起作用．
Elongation of pollen tubes of Cucumis sativus was evidently promoted by 5 mg/L IAA and the germination of pollen was completely inhibited by 100 mg/L IAA.Prior to pollen germination, the endogenous cAMP contents reached their peak when pollen was treated with 5 mg/L IAA solution. It may be considered that cAMP plays a role in IAA promoting the elongation of pollen tubes.
