Effect of nitrogen on starch and protein content in grain influence of nitrogen doses on grain starch and protein accumulation in diversified wheat genotypes

摘要

Aim: Nitrogen is a critical input involved in plant metabolism growth and in different biochemical processes. Nitrogen participates directly in amino acid, protein and other cellular component syntheses, which are required for plant growth and development. Therefore, nitrogen application greatly influences starch and protein composition and, very little information is available on the effect of nitrogen fertilizer on protein sub fractions and starch components with little emphasis on quality characteristics. Therefore, the aim of the study was to evaluate the genotypic variation based on starch and protein accumulation under different doses of nitrogen.
