Effects of NaCl and melatonin on salt secretion of salt glands ofL. bicolorleaves.a-d, the ability of salt secretion of leaves with leaf disc method,a, 0 + 0, 0 mM NaCl+ 0 μM MT;b, 0 + 5, 0 mM NaCl+ 5 μM MT;c, 300 + 0, 300 mM NaCl+ 0 μM MT;d, 300 + 5, 300 mM NaCl+ 5 μM MT;e, The total amount of Na⁺secreted by a single leaf;f, the total amount of Na⁺secreted by a salt gland. The values are the average of five biological repeats ± standard deviation. According to Duncan’s multi-range tests, bars that there were significant differences atP < 0.05 are labeled with different letters
