Regulation of grain size within a developing ear of bread wheat


, : Regulation of grain size within a developing ear of bread wheat. Indian Journal of Agricultural Sciences 57(10): 710-715

Inter- and intra-spikelet differences were studied in grain size of 'HD 2009', 'HD 4502' and 'Kalyansona' varieties of bread-wheat (Triticum aestivum Linn. emend. Flori and Paol.). The developing grains capable of producing higher levels of auxins could mobilize greater proportions of assimilates from flag leaf to grains, leading to their higher accumulation in grains and resulting in bolder size at maturity.
