Chickpea (Cicer arietinum L.) under stress: A review of drought and heat impact
Sevdalina Ninova, Ivanina Vasileva
Резюме: Drought and heat stress are major abiotic factors limiting chickpea (Cicer arietinum L.) growth and productivity, adversely affecting both physiological and biochemical processes. Based on the work of various scientists, we tried to summarize the effects of water deficit and elevated temperatures, and the subsequent drought and heat stress on chickpea growth, yield, and stress response mechanisms. Differences in biomass quantity and seed yield were observed depending on whether the investigated accessions were susceptible or tolerant to stress. In some cases, biochemical analyses revealed increased accumulation of osmoprotectants, such as proline and soluble sugars, suggesting their role in osmotic adjustment. The role of various compounds with proven antioxidant activity, as well as the activity of antioxidant enzymes including superoxide dismutase, catalase, and peroxidase, was also taken into consideration. This review aims to reveal the multifaceted response of chickpea to drought and heat stress, involving physiological, biochemical, and molecular adaptations. Understanding these mechanisms is vital for developing drought- and heat-tolerant chickpea cultivars, contributing to agricultural sustainability and food security under changing climate conditions.
