摘　　要：以印度南瓜强雌品系088-3、2013-12和强雄品系9-6为试材,通过喷施乙烯利和乙烯抑制剂(AVG和STS),探讨乙烯对印度南瓜性别表现和花发育的影响。结果表明:通过乙烯利处理,3个印度南瓜品系的单株雌花数增加,第1雌花节位提前。通过乙烯抑制剂处理,3个品系的第1雌花节位延后,单株雌花数减少。3个品种对外源乙烯的处理反应不同。强雌性材料(2013-12和088-3)对乙烯利和乙烯抑制剂处理表现为敏感,而强雄材料9-6表现为不敏感,这可能与不同品种的基因型及对乙烯和乙烯抑制剂的敏感性不同有关。另外,在乙烯利处理后,3个印度南瓜品系均出现了不同程度的败育情况和不完全雌蕊的雄花。The sexual expression and flower development of 3accessions of Cucurbita maximaincluding 2strong female accessions（088-3and 2013-12）and 1strong male accession 9-6were investigated by spraying ethephon and ethylene inhibitor（AVG and STS）.The results showed that the female flower number of 3accessions of C.maximaincreased and the first female flower node advanced through ethephon treatment.On the contrary,the female flower number of 3accessions of C.maxima decreased and the first female flower node delayed through ethylene inhibitor treatment.3accessions of C.maxima had different response to exogenous ethylene treatment.Strong female accessions（088-3and2013-12）was sensitive to ethephon and ethylene inhibitor treatment,while strong male accession 9-6was insensitive to ethephon and ethylene inhibitor treatment,which could be related with the sensibility to ethephon and ethylene inhibitor of different genotypes.Moreover,3accessions of C.maximaall appeared different degrees of abortion and incomplete pistil of male flowers.
