The peroxidase isozymes in the petals, anthers and ovaries of pomegranate cylindric and trumpet-shaped flowers were analysed at the begining of bloom by polyacrylamide gel electrophoresis. The characterastics of peroxidase isozymes zymogram in different organs of the two kinds of flowers were studied. It was discovered that the activation of peroxidase isozymes in the ovaries of cylindric flowers Was stronger than that in the ovaries of trumpet-shaped flowers, and on the contrary, the activation of peroxidase isozymes in the anthers of cylindric flowers was weaker than that in the anthers of trumpet-shaped flowers. The contents of soluble sugar, soluble protein and nucleic acid in the ovaries of the two kinds of flowers were tested. It was showed that the contents of these biochemical substances in the ovaries of cylindric frowers were all highter than those in ovaries of trumpet-shaped flowers. The authers infered the fomation of trumpet-shaped flowers might be related to the deficiency of nutrient supply directly.
