Abstract
Salt stress increases the accumulation of toxic ions in chloroplasts of higher plants and is associated with decreased photosynthesis. A pot experiment was conducted to investigate the effect of foliar application of gibberellic acid (GA3, 288.7 µM), kinetin (232.3 µM), and salicylic acid (362 µM) under salt stress (0, 2, and 4 g kg−1 dry soil) on two sweet sorghum varieties (Yajin 13 and Yajin 71). The investigation parameters included the content of Na+, K+, Ca2+, P, and Mg2+, photosynthetic rate, transpiration rate, stomatal conductance, and membrane permeability. The results indicated that Na+ content increased gradually with salt increase. Photosynthetic rate, stomatal conductance, transpiration rate, and K+ content were significantly decreased due to high salt concentration. The medium salinity level of 2 g NaCl per kg dry soil decreased P, Ca2+, and Mg2+ content. Of hormonal treatments, GA3 and kinetin caused significant increase in photosynthetic rate, stomatal conductance, and transpiration rate. Salicylic acid was the best hormone treatment for reducing membrane permeability and Na+ content under salt stress. Yajin 13 had less Na+ content than Yajin 71, and was more tolerant to salinity than Yajin 71.
