Abstract: The study entitled “Effect of Salicylic acid on Morpho-Physiological and Biochemical attributes in Normal and Late Sown genotypes of Wheat (Triticum aestivum L.) under high Temperature Stress†field experiment was carried out at the Agriculture Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi with two wheat genotypes (HUW- 510 and HUW- 468) during the Rabi season 2017-18. Two wheat genotypes were sown on 15th November (timely sowing) and 15th December (late sowing) under standard package of practices. The effect of Salicylic acid on morphological and biochemical parameters of wheat genotypes under high temperature stress was determined. Salicylic acid at pre flowering and post flowering stages of two normal and late sown wheat genotypes was applied as foliar spray. SA treatments used in the present study are 1.0, 1.5, 2.0 mM SA. Analysis was done at pre flowering and post flowering stages in both genotypes of normal and late sown. In the present investigations, Morpho-physiological parameters like plant height, leaf area and dry weight were more influenced whereas less influenced were root length and total chlorophyll content and biochemical parameters are highly influenced by salicylic acid treatment such as proline content, protein content, Nitrate reductase activity. The highly responsive genotype was normal sown HUW-510 and low responsive genotype was late sown HUW-468. Salicylic acid at a concentration of 2mM SA was found to be the most effective in both genotypes. Thus, it indicates that the importance of these characters in selecting breeding programmes for development of superior genotypes. Results signify the role of salicylic acid in regulating the heat stress response of wheat; hence it could be used as a potential growth regulator under heat-stress as well as non-stress condition.
