Abstract:

In order to select an quantity of alkaline-salt tolerance of tree species, the author had reviewed the identification of alkaline-salt tolerance of tree species, the achievement acquired in the improvement of alkaline-salt tolerance of tree species by using conventional breeding and modern biotechnology. The current problems and the future direction for breeding alkaline-salt tolerance of tree species had also been discussed. Because the effect on alkaline-salt tolerance of tree species was complex, the problem of transgenic engineering and marker assisted selection was existent. The study on hereditary patterns on alkaline-salt tolerance of tree species and marker assisted selection were put forward. Also, some suggestions were as references for us to study salt resistance identification in tree species and breed new plants of salt-tolerance and in order to develop the ecological efficiency of forests of saline-alkaline land.
