Abstract:
Cold stress in chickpea mostly affects the Northern parts of India as temperatures drop below 15 °C at flowering stage which can limit chickpea growth and vigor. In the present investigation the effects of cold stress on morpho-physiological traits in chickpea genotypes were studied at reproductive stage. Pot experiment was conducted simultaneously in the control and treated conditions respectively at Division of Plant Physiology, Chatha, and field trial were conducted in October, 2020-2022 at ACRA Dhiansar SKUAST, Jammu. The factors to be studied 32 chickpea genotypes and cold stress at flowering stage. Analysis for plant height, no of branches per plant, no. leaves per plant, dry weight of stem, leaves, and SPAD value of control and cold-stressed plants were recorded. The results showed that cold stress induced at flowering stage declined the Plant height, number branches, number of leaves per plant and dry weight in stress condition ICCV 88506 genotype followed by Pusa 362 and ICCV 96030 and other chickpea genotypes were at par whereas RSG 896 and PBG 5 were performed minimum during cold stress condition in pot as well as in field. This study imply that cold stress greatly influences morphological and physiological functions that affect plant growth and yield production in chickpea genotypes.
