ENDOGENOUS HORMONES, GROWTH AND YIELD OF BARLEY PLANTS AS AFFECTED BY BENZYL ADINENE UNDER DIFFERENT SALINITY LEVELS
Botany Dept., Agrlc. Dlv. National Re.earch Centre, Dokkl, Cairo, Egypt
Abstract
A pot experiment was conducted in the greenhouse of the National Research Centre. Dokki. Cairo, Egypt during the winter season of 200012001 to evaluate the effect of 6-benzyl adenine under different salinity levels on growth, yield and the concentration of different endogenous hormones in barley plants r:v. Giza 124. Plant height, number of tillers and leaves/plant, dry weight of shoots No. and length of spices and straw, grains and lotal yield/plant were decreased as the salt concentration increased in water used for irrigation of barley plants. BA (6-benzyl adenine) treatment were slightly affected growth and yield characters. 1M, GA and Cytokinins decreased but ABA concentration was reversely responded by salt stress. Spraying BA at 50 mgJI raised the endogenous concentration of GA, 1M and Cytokinins by 13.76, 12.97 and 22.77 % and lowered the concentration of ABA by 20.97 %, SA treatment contracts the effect of salt stress on the different estimated hormones.
