【目的】研究不同时期干旱胁迫对果实品质的影响,为提升果实品质及节水灌溉提供理论依据。【方法】以‘山下红’温州蜜柑(Citrus unshiu Marc.)为材料,分析了果实发育过程中细胞分裂期、果实膨大期及较长时期连续干旱后果实外在和内在品质的变化。【结果】与对照相比,不同果实发育阶段干旱胁迫后果实体积均呈下降趋势,细胞分裂期、果实膨大期、连续干旱期果实体积分别下降22.5%、49.6%、65.7%。对各处理成熟果实分析显示,连续干旱期处理总酸较对照升高86%,总糖升高6.5%,细胞分裂期干旱总酸较对照升高37.3%,总糖下降6%,果实膨大期干旱总酸较对照升高31.8%,总糖升高26.1%。发育过程中果实分析显示...

【Objective】Moderate drought is an important means to regulate fruit quality. Citrus grows in southern China, where abundant rainfall happens during cell division but less rain during fruit enlargement, which is sensitive to drought. The impact of drought on fruit quality during different periods remains unclear. In this regard, the effect of drought on fruit quality at different fruit development stages was examined in order to provide strategy for improving citrus fruit quality with water-saving irrigation. 【Methods】The experiments were ca...
