Effects of Salt Stress on Physiological Growth of Lettuce
[Objective] With the increase of saline soil area,more and more attention in plant growth in saline environment had been paid.[Method] With lettuce as test material,under different salt concentrations,the physiology and growth of lettuce were studied.[Result] With the increase of NaCl concentration,chlorophyll content of lettuce decreased,leaf color became yellow,malondialdehyde content in cells increased,and the damage to the cell membrane was serious.At high salt concentration condition,root and plant growth decreased.At the NaCl concentration of 225 mmol/L,the plants all died.[Conclusion] Lettuce wasn't suitable for the growth under high salt environment.
