A review on impacts of high temperature stress on Indian mustard (Brassica juncea)


Pulipati Ramya Sree

Indian mustard (Brassica juncea), an amphidiploid with genetic constitution of 2n=36 (AABB) and a member of “Cruciferae” family grown as an cool season crop in many parts of the world. It is second most important vegetable oilseed crop in India and ranks 5th position in vegetable oil economy sharing 7.4% of world oilseed output. In agriculture, abiotic stress factors are the primary limiting factor for plant development and productivity. Being an c3 plant and thermosensitive nature this crop is adversely affected by high temperature stress due to climate changing scenarios. Abiotic stress mainly high temperature stress severely affects many physiological (chlorophyll content, osmotic water potential) morphological (Plant height, leaf area index, dry matter accumulation) and biochemical (antioxidant enzymes) mechanisms and disrupt normal plant growth and development, especially in the early phases of development, which is a major concern in many agricultural regions across the world. Climate change is an issue today, and researchers are working to understand its influence on crop development and production, as well as to discover appropriate management solutions to keep crops productive in the face of changing climates. In this review paper information on impacts of high temperature on morphological, biochemical, physiological, yield and yield attributing traits are discussed and the adaptive strategies, Breeding mechanisms for heat stress are discussed.
