Abstract:
Taking one-year-old cutting seedlings of Lycium barbarum as material,osmotic regulation substances,chlorophyll content and growth appearance parameters were studied under the stress of 0.2%,0.4%,0.6%,0.8%,1.0% salinity of soil,with water as control.The results indicated that the content of Na+,K+ and Cl- in different organs were different.The content of Na+ and Cl- were the highest in leaves and were no significant differences in roots and stems.The content of K+ was also different among organs,leaves＞stems＞roots.The content of Na+,K+ and Cl-in overground parts were higher than that in underground parts.The content of Na+,Cl-,soluble sugar,proline increased with increasing salt concentration.The content of chlorophyll was no significant differences in May and decreased with increasing salt concentration in June,July and August.Survival rate,relative growth rate and salt appearances values decreased with increasing salt concentration.There was a significant correlation between salt appearances values and each index,which showsed that the level of salt tolerance of Lycium barbarum was the result of many factors working together.From the above analysis,it could be considered that Lycium barbarum had more salt-tolerance and was suitable for coastal saline areas for afforestation.
