EFFECT OF DROUGHT SIMULATION ON GRAIN WEIGHT, PROTEIN AND LYSINE CONTENT OF BREAD WHEAT (TRITICUM AESTIVUM L.) MAQBOOL AHMAD AND M. AFZAL ARAIN Abstract: Effect of drought simulation (terminal, preanthesis, postanthesis and full irrigation) on grain weight, protein and lysine content in different strains of bread wheat viz., Chakwal, Pavon, AZS-4 and AZS-17 was studied under field conditions. Water stress especially terminal and postanthesis decreased (P< 0.05) grain weight. whereas protein and lysine content significantly (P < 0.05) increased. Correlation between grain weight and protein content was negative and highly significant (r = -0.672, n= 16). Reduction in endosperm due to water deficit could be the probable cause for lower grain weight and enhanced protein content. Nuclear Institute of Agriculture, Tando Jam- 70060, Sindh, Pakistan. |
