以温州蜜柑膨大期果实为材料,设置基质相对含水量为40%、30%和20%的3个胁迫处理,研究干旱对果实品质形成特点和柠檬酸调控相关转录因子表达模式变化;利用氘水(D2O)示踪法明确柑橘干旱复水后的水分吸收运输和分配规律。温州蜜柑果实膨大期干旱严重抑制果实外在品质的形成,干旱胁迫10 d后,果实横径、纵径、单果质量均显著下降,40 d时各处理横、纵径较对照减少18.33% ~ 23.82%,单果质量降低45.17% ~ 48.67%,各干旱处理间无显著差异。各处理干旱胁迫40 d时果实可溶性固形物显著增加47.7% ~ 59.3%,果糖升高63.25% ~ 78.77%,但蔗糖和葡萄糖增量不大,处理间糖组分差异不大。对照果实柠檬酸含量随生长发...

Using Satsuma mandarin fruits at enlargement stage as the material, three stress treatments with the substrate relative water content 40%,30% and 20% were set. Afterward, fruit quality changes and expression patterns of transcription factors regulating citrate accumulation were studied under drought conditions. Using deuterium water (D2O)tracer method, the law of water transportation and distribution in citrus tree after re-watering could be cleared. Drought stress at fruit enlargement stage inhibited fruit growth and fruit size severely. After...
