Two pot experiments were conducted at Agricultural Farm, Faculty of Agriculture, Mansoura University during the two successive seasons of 1990 and 1991 to investigate the effect of salinity (0, 1000, 2000 and 3000 ppm) of irrigation water and cycocel (0, 1000 and 2000 ppm) on vegetative growth, photosynthetic efficiency and productivity of snap bean plants. The obtained data could be summarized as follows: 1-The irrigation water contained salinity up to 1000 ppm had no adverse effect on the growth parameters, particularly plant height, fresh and dry weight of whole plant and its organs. 2-All plant growth parameters gradually and considerably deceased by increasing level of salinity between 1000 and 3000 ppm. 3-Photosynthetic pigment contents decreased with increasing salinity level, total leaf area and net assimilation rate followed the same trend. 4-Salinity levels had no clear effect on the appearance of the first flowers but the period between flowering to the pod harvesting was more shorter, than control with increasing the salinity levels. 5-The pod yield and pod characteristics of snap bean decreased by increasing salinity levels. 6-With increasing salinity N and K contents in leaves tissues were significantly reduced whereas, P content was not affected. 7-Total fresh and dry weight, total leaf area/plant, net assimilation rate and pigments content tended to increase with the application of cycocel under salinity effect. 8-Cycocel application had no great effect on flowering processes and yield characteristics. 9-Cycocel treatments caused an increase in N and a decrease in P and K contents.Under different salinity levels, cycocel application increased the N and decreased P and K contents. 10-Spraying cycocel on the snap bean plant which were irrigated with saline water could be counteracted the inhibition effect of salinity. Since the results indicated that, using cycocel increase the resistance of snap bean to salinity up to 2000 ppm.

“…They concluded that Physiological response of Vicia faba to prohexadione-calcium ... inhibition of photosynthetic pigments of bean leaves irrigated with NaCl may be attributed to the inhibition of assimilate translocation. Bhivare et al (1988) reported that salinity stress markedly affected the rate of photosynthetic carbon assimilation of bean leaves. Reddy & Vora (1983) attributed the reduction in photosynthetic pigments of wheat leaves grown under salt stress to increase in the activity of chlorophyllase enzyme.…”

Changes in the activities of oxidative enzymes (indole acetic acid oxidase, peroxidase and catalase), endogenous hormones (gibberellic acid (GA3), indole acetic acid (IAA), abscisic acid (ABA) and cytokinins (AsZeatin), photosynthetic pigments (chlorophyll a, chlorophyll b and carotenoids), total carbohydrates, total soluble sugars, amino acid proline and vegetative growth parameters were used as indicators to explain the physiological role of the growth retardant prohexadione-calcium on Vicia faba seedlings 40 days after sowing under salinity stress for 30 days. The obtained results show that soaking faba bean seeds prior to sowing at different concentrations of prohexadione-calcium (0, 10, 20 and 30 ppm) significantly increased the activities of indole acetic acid oxidase (IAA-oxidase) and peroxidase enzymes, but decreased the catalase enzyme activity as compared with their respective control. Application of prohexadione-Ca caused markedly decreases in the endogenous contents of gibberellins and indole acetic acid (IAA) but increased the levels of natural growth inhibitor abscisic acid (ABA) and cytokinins in the shoots of faba bean seedlings. All the prohexadione-Ca concentrations increased the contents of amino acid proline, photosynthetic pigments (chlorophyll a, chlorophyll b and carotenoids), total carbohydrates and total soluble sugars in faba bean seedlings grown under salt stress. Application of prohexadione-Ca decreased significantly seedling height and shoot fresh weight but significantly increased shoot dry weight.
