Evaluation the effect of glycine betaine and proline on some morphophysiological, enzymatic, growth and flowering characteristics in Pelargonium spp. in drought stress

This study for evaluation the effect of glycine betaine and proline on some morphophysiological, enzymatic, growth and flowering characteristics in Pelargonium spp. in drought stress, in factorial experiment in a completely randomized design with 13 treatments, 3 replication and each treatment with 3 plant, a total 117 plant were conducted. Treatments includ reaction between glycine betaine and proline spray each on by two concentration 50 and 100 ppm and drought stress 25, 50 and 75 field capacity, done. Apply the treatments about one month after planting rootstock cuttings in a suitable media, done and sampling and evaluation of the desired traits were also performed at the time of formation of flower buds. Morphophysiological and enzymatic traits of the plant such as air and root fresh weight, air and root dry weight, cell membrance stability index, anthocyanine of petals, total chlorophyll of leaves, proline, protein, superoxide dismutase and peroxidase activity and flower life on plant were evaluated. The results showed that Control had the most effect on the improvement of traits such as air and root fresh weight, air and root dry weight, cell membrance stability index, anthocyanine of petals, total chlorophyll of leaves, protein, superoxide dismutase and peroxidase activity and flower life on plant and highest nnd lowest proline respectively in DS 75% Fc+GB50ppm and Control, done. Also Control treatment with 8.6 days was highest and DS 75% Fc+GB50ppm treatment with 4.3 days had the least flower life on plant
