【目的】分析水涝胁迫下涝耐受型冬瓜RW101和涝敏感型冬瓜SW15幼苗的形态结构及生理响应差异,为获得冬瓜耐涝性指标及创制耐涝冬瓜种质资源提供理论依据。【方法】对5叶1心期的涝耐受型冬瓜RW101和涝敏感型冬瓜SW15分别进行水涝胁迫0、24、48、72和96 h处理,对比分析其应对水涝胁迫的形态结构及生理响应差异。【结果】RW101在水涝胁迫48 h后即可萌发不定根,且随水涝胁迫时间延长,不定根数量和长度明显增加;SW15在水涝胁迫72 h后才萌发不定根,且数量和长度均显著低于RW101（P

【Objective】In order to obtain the waterlogging tolerance index of wax gourd and provide the reference for establishing the germplasm resources of wax gourd with resistance to waterlogging,the morphological structures and physiological responses of seedlings of tolerant wax gourd RW101 and sensitive wax gourd SW15 under waterlogging stress were analyzed.【Method】The waterlogging tolerant wax gourd RW101 and sensitive wax gourd SW15 were flooded for 0,24,48,72 and 96 h respectively during the 5-leaf and one-phyllophore stage.The differences of...
