Study on salt tolerance of 9 varieties of Lolium spp.in germination and seedling stage

摘要

Loliumspp.is one of the most important germplasm resources in many parts of China,and includes many valuable characters,for examples drought, cold and barrenness tolerance,except salt tolerance.And it can fit in fertile,moist,well-drained soil even sticky soil,and it can adapt on slightly acidic soil of pH 6-7.When they plant in a land with high salt content and alkaline, they will be at salt stress. So many researchers had made a lot of amazing efforts to find several methods to improve their salt tolerant. Now we can carry some experiment on 9 varieties to evaluate their ability of salt‐tolerance.
