Abstract

Abstract A nutrient culture experiment was conducted under controlled greenhouse conditions to study the effect of different solution levels of zinc on soluble protein, tryptophan and RNA content of wheat plants at different physiological stages of growth. The highest dry matter yield and soluble protein, tryptophan and RNA content of plants were observed at 0.5parts/10 6 level of zinc at all stages of growth. On either side of this level, a fall in dry matter yield and soluble protein, tryptophan and RNA content of plants was recorded. A balance between phosphorus and zinc concentration seems to be needed for normal metabolic functioning of plants.
