Abstract: The contents of endogenous hormones in flower buds and leaves,including IAA,Z+ZR,GA3,ABA of two male sterility lines(CMS and GMS) and their corresponding maintainer lines of Pepper(Capscium annuum L)were assayed using ELISA.The experiment also analyzed the ratio of the endogenous hormones.The results as following:The changing tendency of endogenous hormones contents including IAA,Z+ZR,GA3,ABA in the flower bud ofcMS and its corresponding maintainer lines consists with the tendency in GMS and its corresponding maintainer lines,that is the contents of IAA,Z+ZR,GA3 and ABA in male sterile lines are lower than in the maintainer lines.There also have the same contents changing tendency of IAA,Z+ZR,GA3 and ABA in the leaves incMS and GMS,that is the contents of endogenous IAA,Z+ZR,GA3,ABA in male sterile lines are higher than in the maintainer lines.The ratio of endogenous hormones including IAA/ABA,(Z+ZR)/ABA,GA3/ABA in the flower buds has the same changing tendency incMS and GMS,that is the ratio of male sterile lines is lower than of the maintainer lines.In conclusion,the results indicate that the changes of hormones in the regulating male sterile have the same rules and the male sterile of pepper may have same traits in the mechanism of biochemistry and biophysics,although the dominating gene of the GMS andcMS is different.
