Changes in peroxidase, indole-3-acetic acid oxidase and amylase activity in ‘grass clump’ hybrid of wheat and its parents

Abstract

Growth pattern and changes in the activity of enzymes have been studied in a ‘grass clump’ hybrid of wheat obtained from a cross between CPAN 1481 (female parent) and IWP 19 (male parent). Growth of the ‘grass clump’ hybrid is less than both parents even at the seedling stage (up to 96 h). The pattern of peroxidase activity in axis and endosperm of the grass clump hybrid is similar to the female parent in dark and to the pattern of the male parent in light. Indole-3-acetic acid (IAA) oxidase activity is generally higher in the hybrid compared to both the parents. Amylase activity is higher in the hybrid in dark closely resembling the female parent while in light the pattern of activity appears to be closer to the male parent in axis and root.
