Abstract: 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.
