Abstract

Abstract: Nuclearmale sterile G17AB line watermelon was chosen as xperimentalmaterial. Changes of endogenous hormones and polyamines contentwere compared between male sterile flower buds and male sterile flower buds. The result showed that in male sterile flower buds, the IAA content and GA_Scontentwere lower while the ZRs content was higher than that in male fertile flower buds, and the peak value of ABA content appeared earlier. In addition, the changes of polyamineswere abnormal in male sterile in male sterile flower buds.

Key words: Watermelon, Nuclearmale sterility, Endogenous hormone, Polyamine
