Progress in the Breeding of Saline-tolerant Somatic Mutant Trees

本文综述了组织和细胞培养筛选林木耐盐体细胞突变体的研究进展，论述了确定耐盐体细胞突变体的生理生化研究工作，简单介绍了ＤＮＡ分子遗传标记在这一领域的应用情况，并对林木耐盐突变体育种进行了展望。

It is necessary to engage in the breeding of saline tolerant trees, in order to utilize and improve the large areas of saline affected soils on the world. Tissue culture could directly induce and screen the saline tolerant somatic mutants of plant and opens a way for the breeding of saline tolerant tree. This paper presents the progress in the screening saline tolerant somatic mutant trees through cell and tissue culture and describes the physiological and biochemical research of identifying the saline tolerant mutants. Utilization of molecular genetic markers in this field is discussed and the prospect of forest saline tolerant somatic mutants is given.
