为了选育出更多的抗盐碱性的新树木种类,综述了树木耐盐碱性的鉴定指标,国内外利用常规育种技术和现代生物技术在树木耐盐碱育种方面的主要进展,并指出树木耐盐碱育种中存在的问题和研究方向,发现盐碱胁迫对树木生长的影响极为复杂,基因工程育种还存在诸多问题,分子辅助育种应用较少,今后还需加强树木耐盐碱性的遗传规律及树木分子育种的研究,旨在为树木耐盐碱性鉴定及耐盐碱树木新品种的选育提供参考,以期更为有效地提高盐碱地区森林的生态效益。
In order to breed more kinds of new trees resistant to salinity and alkalinity, the identification index of salinity and alkalinity of trees, the main progress of salinization breeding of trees using conventional breeding techniques and modern biotechnology at home and abroad are summarized. Salinity and alkali resistance of trees in breeding problems and research directions and found that salt and alkali stress on the growth of trees is extremely complex, there are still many problems breeding gene engineering, molecular breeding less auxiliary applications, the future need to strengthen the salinity of trees Genetic laws and tree molecular breeding research, aims to provide a reference for the identification of salt and alkali tolerance of trees and the breeding of new varieties of salt-tolerant trees, with a view to more effectively improve the ecological benefits of the forest in saline-alkali areas.
