Among them, 63 species have been cultivated ,only 27.5% are middle salt tolerance degree plants, most of them are light salt tolerance degree plants, no species is high salt tolerance, the research also found there are 24 species of wild salt tolerance plants ,10 of them are high valuable plants of greening in salt affected soils and are recommended.
This review tries to analyze the relationships between the RGA and R genes, and summarize the important functions of RGA in mapping R genes and the evolution of R genes. It also believes that RGA can be useful as candidate genes to detect and eventually isolate numerous R genes in agronomically valuable plants.
An understanding of the physiological factors important to growth and agar production of the Gelidiales would be useful for successful mariculture of these commercially valuable plants.
Evidence is presented here for the spontaneous long-term community enrichment of an area with valuable plants in a cyclic or iterative fashion, in the context of an existing fallow utilization scheme in the Amazon.
Basic knowledge of the life form of economically valuable plants such as rattan is essential if rational decisions are to be made about their long-term management and sustainable utilisation.
The common chemical methods have been used to study the chemical constituents of the valuable plants gathered from Lijiang,Yuxi, Xishuangbanna, Yunnan. These plants amount to fifty species and belong in thirty one families. The major constituents of these plants have been analysed qualitatively.
