Summary

By application with 2-aminoethanol (2-AE) and choline chloride (CC) in pot experiments the effect of drought stress on barley plants was diminished. In treated plants an increase of the grain yield by 14% (2-AE) and 40% (CC) and a decrease of the stress metabolites glycine betaine and trigonelline was observed. Additionally, treated barley plants showed higher yields of essential amino acids as well. The contents of proline (stress indicator) and arginine (precursor of the stress metabolite putrescine) of treated plants were by 12% and 22% respectively, lower than in untreated plants.
