摘要：

【目的】探讨薄皮甜瓜内源激素对夜间不同温度的应答及果实内源激素与果实发育之间的关系。【方法】采用HPLC方法,测定果实膨大期不同夜温处理后薄皮甜瓜果实中内源激素的含量,分析不同夜温处理下内源激素含量与单果重增长率的相关关系。【结果】薄皮甜瓜果实中内源GA3和ZT含量均在果实膨大前期出现高峰,IAA在果实膨大后期出现高峰,ABA含量一直维持较低的水平。不同夜温处理后薄皮甜瓜果实中内源激素含量变化明显。与其它处理相比,夜温9℃处理后,果实内源GA3、ZT、IAA含量均明显降低,GA3/ABA、ZT/ABA明显减小,ABA含量在果实发育后期明显升高,均达到极显著水平。夜温18℃处理后果实内源GA3、GA3/ABA含量明显低于夜温15℃和12℃处理。在薄皮甜瓜整个夜温处理过程中,夜温15℃和12℃间的内源激素无显著差异。进一步分析果实内源激素与果实膨大的关系表明,GA3/ABA与单果重增长率呈极显著正相关,不适宜夜温下其二者直线相关的斜率较小,其中9℃最小。ZT/ABA与单果重增长率间,除夜温15℃和18℃达到显著正相关外,其它夜温处理均不显著。【结论】不同夜间温度对果实内源激素含量的影响不同,GA3和GA3/ABA可能与薄皮甜瓜果实生长具有一定的关系,同时还与其它因子有关。
