| dc.description.abstract | Wheat is one of the main staple foods in India as well as in the world. The yield and grain quality of the crop are severely affected by stress conditions like heat and water stress. In the present study experiments were conducted to delineate the effect of plasma and microbial consortia under heat stress condition and effect of nano ZnO, nano chitosan and microbial consortia under water stress condition. Field experiments were done at Norman E. Borlaug Crop Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar in 2018-19, using Randomised Block Design. The “HD 2967” variety of wheat was used for seed treatment, sampling for molecular and biochemical profiling was done at three different growth stages i. e., booting, heading and grain filling stage. In both heat and water stress conditions, the contents of photosynthetic pigment, relative water content, protein, proline, sugar, and antioxidants were found to be highest in the combination plasma + MC I and nano ZnO + chitosan NPs + MC I treatment respectively, which helped wheat combat water stress condition. The grain protein, quality of grain and the yield were also best in this treatment. Maximum increase in Zn and Fe concentration was also recorded using this treatment. In case of heat stress condition, similar results were found for all the above parameters in case of plasma + MC 1 treatment. As the immunity of plant decreases during abiotic stress condition they become more susceptible to attack by biotic factors reducing plant growth, development and yield. So antimicrobial property of nano ZnO and chitosan nanoparticle was assessed in antifungal and antibacterial experiments. Both nano ZnO and nano chitosan were found to have inhibitory effect, but the combination of these two nanoparticles was observed to have maximum antimicrobial properties both in case of bacteria and fungi. Our research finding reveals that nano ZnO, nano chitosan and combination of both nanoparticles can be used to reduce the losses caused by abiotic stress in wheat. | en_US |
