Comparative Analysis of Canopy Cooling in Wheat under High Temperature and Drought Stress

The size and the weight of wheat grains vary across length each spike (Triticum aestivum L.). High temperature water scarcity often reduce single grain weight, this reduction also varies length. Plants tend to cope with high drought stress through inherent mechanisms such ascanopy cooling transpiration, which can contribute yield stability. effect canopy on average at different positions in is still unknown. In study, we planned assess role temperature, yield-related traits, shape final weight. For two years (2017–2018 2018–2019), fifteen diverse genotypes released for cultivation environmental conditions were grown field. They examined spikelets spike?1, number spike’s basal, median, distal regions. Pearson correlation coefficient (r) was obtained all pair-wise combinations traits under treatments shapes. results indicated that cooler correlated normal three within irrespective stress. advantage improving grain-filling regions more conspicuous compared non-stressed conditions.
