Abstract:
Taking Salix matsudana Koidz,Salix babylonica,Populus deltoids,Populus tomentosa Carr,Limonium bicolor,Rumex acetosa Linn as test material,the salt tolerance of the plants were analyzed through random selection of plants and leaves in the saline land and by membrance permeability in vitro,in order to compare the salt tolerance of plants for the saline land’s greenery.The results showed that the membrance permeability and membrance injury rate of Populus tomentosa Carr was higher than Populus deltoids under salt stress.When the salt concentration reached 4%,the membrance permeability of Populus tomentosa Carr was 23 percentage point higher than Populus deltoids.Under salt stress,there were the same trend between membrane permeability and membrane injury rate of leaves of Limonium bicolor and Rumex acetosa Linn.Among them,the two indicators of Limonium bicolor was less than Rumex acetosa  Linn 1~5 percentage point.The membrance permeability and membrance injury rate of Salix matsudana Koidz was stronger than Salix babylonica 6 percentage point under treatment of 1% NaCl.Higher salt concentrationof 2%~6% NaCl,the indicators in Salix matsudana Koidz was less than Salix babylonica 3~10 percentage point.According to the membrance permeability of leaves under salt stress,salt tolerance was Populus deltoids>Populus tomentosa Carr,Limonium bicolor>Rumex acetosa Linn,Salix matsudana Koidz>Salix babylonica,salt tolerance order of six kinds of plants was Populus deltoids>Limonium bicolor>Rumex acetosa Linn>Salix matsudana Koidz>Salix babylonica>Populus tomentosa Carr.
