Description

The north-east steppe of China is semi-arid. Forty-seven species of C3 plants and 53 species of C4 plants were defined. The C pathway of the 42 forage species among the total l 00 species is firstly identified by determining the ratio between RuBPCase/PEPCase (RIP) and observing the Kranz leaf anatomy. The abundance of C4 plants decreases with decreasing precipitation and the intensity of soil sandesation, and increases with lower latitude and increased soil salinisation.
