Abstract:

Micronutrients are essential for human health and crucial for plant survival. Increasing temperature and heat are major abiotic stress which limits yield and nutritional quality of wheat. The objective of study is to evaluate the effect of heat stress on boron (B) micronutrient accumulation in 18 wheat varieties at three phenological stages (Booting and grain filling and maturity). Pot experiments were conducted in randomized block design with three replications during rabbi 2012-13 at DRPCAU, Pusa, Bihar. Results showed the accumulation of micronutrient under heat stress in booting, grain filling and maturity decreased significantly in flag leaf, spike and grain but some varieties enhances the accumulation of micronutrients under heat stress condition significantly. The wheat variety namely C306 (68.29 ppm), MB4010 (53.66 ppm), HD2888 (52.73 ppm), Iepacarabe (49.71ppm), AKAW4008 (41.16 ppm) and Kauz/AA/Kauz (40.73 ppm) are good accumulator of B in flag leaf and varieties F5-995 (75.50ppm), Sonalika (30.83ppm), MonsAld’s (29.93 ppm) and Iepacarabe (21.73ppm) increases boron accumulation in spike under heat stress. The enhanced boron accumulation under high temperature in grain was observed in variety namely AKAW4008 (32.82ppm) and PBW343 (26.94 ppm) respectively. The wheat variety F5-995, PBW343 MonsAld’s and AKAW4189-3 showed overall better micronutrients accumulation in flag leaf, spike and grain under stress condition and appeared as potentially important wheat variety used during heat stress.
