Advances in Seed Germination of Desert Woody Plants under Salinity Stress
Due to low precipitation and high evaporation in desert region, there is often accompanied by soil sali-nization. xeric, xeric shrubs and semi-shrubs and other woody plants are dominant populations in desert ecosys-tems, and their seeds in the long-term evolution evolved the germination strategy adapted to harsh habitats, which ensure plants existence and reproduction. In this paper, it is summarized the effects of desert woody seeds' germi-nation under single salt stress and drought-salt stress, as well as salinity adaptability characteristics of desert woody plant seed germination, which included following three aspects:seed morphological structure, seed dormancy by environment induced and germination behavior. As the desert dry and soil salinization simultaneously occur, it is significant to pay attention on the study of dual-factor and multi-factor impact and mechanism of drought and salt stress on desert woody seeds, which can provide theoretical foundation about that screening and excavation of salt resistance potential of desert woody species, as well as desert vegetation reconstruction and recovery.
