higher PEPC activity in the developing grain than in flag leaf blade and glume during grain development. For 16 of the genotypes studied, the mean PEPC activity in the developing grain or glume at 15 and 25 days after flowering is significantly and positively correlated with final protein content of grain. Enzyme activities in glume and flag leaf blade are positively correlated with final grain weight but the activity in developing grain is weakly and negatively correlated with grain weight | Triticum aestivum |
