![]() Ironically, the threshold temperatures for pea plant and its responses are inconsistent and not yet clearly identified. To combat HS and continue its life cycle, plants use various defense strategies including heat escape, avoidance or tolerance mechanisms. HS during germination and early vegetative stage resulted in poor emergence and stunted plant growth along with detrimental effects on physiological functions of the pea plant. High-temperature stress (30.5-33☌) especially during reproductive phase is known to drastically reduce both seed yield and germination. A reduction in pod yield has been reported from 11.1% to 17.5% when mean daily temperature increase from 1.4 to 2.2☌. HS causes severe yield losses by adversely affecting several traits in peas. In the era of climate change, the overall productivity of pea ( Pisum sativum L.) is being threatened by several abiotic stresses including heat stress (HS). 4Department of Agronomy, Kansas State University, Manhattan, KS, United States.3Feed the Future Innovation Lab for Collaborative Research on Sustainable Intensification, Kansas State University, Manhattan, KS, United States. ![]() 2Indian Council of Agricultural Research-Indian Agricultural Research Institute, Pusa, New Delhi, India.1Indian Council of Agricultural Research-Indian Institute of Vegetable Research, Jakhini, Varanasi, India.Mishra 2 Prakash Kumar Jha 3 Nakul Gupta 1 Rakesh K.
