Abstract
In the greenhouse,pot experiment was conducted to study the effect of 100-400 mmol/L NaCl on the growth and ion distribution of two-year Aloe vera.The results showed that the dry weight and leaf chlorophyll content of Aloe vera appeared indistinctive difference between treatments of 100 mmol/L NaCl and control,the plant dry weight and chlorophyll content showed notable decline under 200 and 400 mmol/L NaCl treatment.The root activity of Aloe vera reached the maximum value under 200 mmol/L NaCl treatment,and it decreased with the increase of salt concentration;Leaf electrolytic leakage under salt stress was higher than the control and increased with the salt concentration enhancement.Under salt stress,content of Na~(+) and Cl~(-) increased with the salt concentration,and it appeared the opposite change for the K~(+) and Ca~(2+) content in Aloe vera.Na~(+) was mainly accumulated in the stem of Aloe vera,content of Na~(+) in the leaves and root was lower;Cl~(-) was mainly accumulated in the leaves and the content in the stem was higher than the root.The content of K~(+) and Ca~(2+) in Aloe vera was lower under salt stress contrast with the control,content of K~(+) in the leaves increased obviously and the Ca~(2+) content decreased.It had lower Na~(+)/K~(+) value and stronger transportation ability for K~(+) and Ca~(2+),which were main reasons to explain salt-tolerance of Aloe vera.
