Wheat seedlings (4 days old) were subjected to varying temperatures of 25, 30, and 35 °C for 7 days in a growth chamber under hydroponic conditions in the absence or presence of α-tocopherol (5 μM). The growth of shoots and roots was inhibited severely at 35 °C. The endogenous α-tocopherol increased in the shoots at 30 °C over the controls but decreased significantly at 35 °C over the previous temperature. The exogenous application of α-tocopherol elevated the endogenous levels in the heat… CONTINUE READING
