Peroxidase System in the Floral Organs of Begonia rex Putz.

Abstract

A highly complicated peroxidative isozyme system was exhibited in the male and female flowers, buds and peduncles in a cultivar., Silver King, of Begonia rex. The peroxidase bands were classified into three groups, i.e., sexual organ-specific, age-specific, and non-specific in floral organ. The bands designated, as 2B, 3B, 3C, 2E, 4E and 3F were found to be specific to male flowers, and 2A, 1D, 3E and 4F were specific to female flowers. The bands occurring in open male flowers were 3C, 2E and 4E, whereas those specific to younger male flowers (buds) were 2C, 1D, 2D, 4D, 2F and 7F. Two bands designated, as 1A and 1B were regarded as non-specific since they appeared in all the floral organs.
