EFFECT BIOCHEMICAL OF HEAT STRESS ON PLANT

Abstract

Heat is one of the main environmental stresses that limits the growth, development and production of plants at the global level as a result of the negative effects it causes at different plant levels. Reactive Oxygen Species (ROS), is one of the biochemical effects of heat produced under aerobic conditions inside plant cells, in normal conditions they regulate cell signals and growth and there is a balance between is formed and is destroyed. However, under of various stresses including heat, this balance is disturbed and leads to the occurrence of disorders in the physiological processes of the plant and the destruction of cell components. The use of chemicals such as osmotic protection compounds, plant hormones, signaling molecules, nutrients, in addition to agricultural practices such as the optimal planting date, irrigation water scheduling, and seed priming process have contributed to reducing the harmful effect of heat and increasing the effectiveness of antioxidants in plants to counter the negative effects of ROS in shade of climate change.
