| 摘 要： | 采用高效液相色谱(HPLC)技术,测定了早蜜梨果实生长发育期间内源生长素(IAA)、赤霉素(GA3)、玉米素(ZT)和脱落酸(ABA)含量及其比值的变化,并分析了各激素与果实发育的关系.结果表明:果肉和种子中IAA含量分别在花后50 d和20 d出现高峰;GA3含量分别在花后20 d和60 d达到峰值;ZT含量的高峰则在花后40 d,而ABA含量分别在花后80 d和90 d最高,随后均呈逐渐下降.IAA/ABA、GA3/ABA和ZT/ABA比值对果实的细胞分裂与膨大起着重要调节作用.

| Abstract: | The changes of endogenous indol-3-acetic acid(IAA),gibberellins(GA3),zeatin(ZT),abscisin acid(ABA) content and ratio during the period of fruit growth and development in Zaomi pear by high performance liquid chromatography(HPLC) were studied,and the relations between endogenous hormones and fruit growth and development were discussed.The results showed that the IAA content of flesh and seed was high in the 50 days and 20 days after anthesis.The GA3 content was high in the 20 days and 60 days after anthesis.The ZT content was highest in the 40 days after anthesis.Moreover,the ABA content was high in the 80 days and 90 days after anthesis,and there were gradually low.The ratio of IAA/ABA,GA3/ABA and ZT/ABA was most important to affect in the cell divisions and expands of fruit. |
