Temperature Stress-Induced Biochemical Changes in Pearl Millet [Pennisetum glaucum (L.) R. Br] Genotypes at the Seedling Stage
The biochemical and physiological changes due to high temperature were observed in twelve genotypes of pearl millet (Pennisetum glaucum (L.) R. Br.). The 20-day-old seedlings were exposed to temperatures of 40 °C for 6 hrs, 44 °C for 4 hrs, and 46 °C for 2 hrs in a BOD incubator. Data on chlorophyll content, activity of antioxidative enzymes and MSI were recorded after two days of treatment. The genotypes HTP94/54, J-2588, and PPMI 1263 performed better, having high activity of antioxidative enzymes. These genotypes can be used in breeding programs to develop high-temperature stress tolerance.
