This study analyses the positional differences in wheat grains in respect
to dry matter accumulation (yield) and to correlate the same with some physiological
and biochemical parameters. Significant variations were discernible in the
two types of grains (bolder and smaller). Smaller grains possessed a higher
activity of catabolic enzymes namely-amylase, invertase, protease and peroxidase
as compared to the bolder grains. The exogenous application of growth promoters
to smaller grains increased their dry matter precipitation, an event that
was otherwise characteristic of the bolder grain.
Key words: Wheat, bolder and smaller grains, plant growth regulators, catabolic
