Foliar spraying alphatocopherol enhances salinity stress tolerance in wheat plant triticum aestivum l

Abstract EN

Alphatocopherol is a vitamin and antioxidant compound that plays a crucial role in amelioration of biotic and abiotic stresses and protects plants from stress – induced cellular oxidation.

The experiment was carried out in a green garden of the Department of Biology, College of Education for Pure Sciences Ibn-AL-Haitham, University of Baghdad during 2018 – 2019 to evaluate the potential effects of foliar application with (0, 50, 100, 150, 200 mg.

L-1) alphatocopherol on growth, yield components and the activity of antioxidant system of wheat plant under sodium chloride stress(0, 75, 150, 225mM.

L-1).

Results indicated that sodium chloride caused reduction in shoot dry weight and some yield components (biological yield, no.

spikelet.

spike-1 and 1000 grain weight)and a significant increase in the endogenous proline acid and alphatocopherol concentration and raised catalase activity.

Foliar spray of alphatocopherol improved salt stress tolerance in wheat plant by increasing all the parameters.
