Mechanism of enhancing photosystem 2 thermoresistance in wheat plants by chlorocholine chloride.

摘要

It is shown that pretreatment of wheat seeds with chlorocholine chloride reduces inhibition of photosystem 2 activity in the first leaves of 10-day-old wheat variety Moskovskaya 35 seedlings caused by heating at 39-41 degrees C for 5-20 min and improves its poststress recovery, probably due to activation of antioxidant enzymes and increase in the level of low molecular weight antioxidants.Notes Translated from Doklady Rossiiskoi Akademii Sel'skokhozyaistvennykh Nauk (2010) No. 3, pp. 7-10 [Ru]
