| Abstract: |
| Carbon isotope techniques have been widely applied in geology, ecology and botany. In this paper, we present the theory of carbon isotope and its indicative function on water use efficient in different plant types、dimensional scale and breeding in drought resistance and water saving. We evaluate the Carbon isotope techniques and expect the development direction in the future. Theoretical and empirical studies have demonstrated that carbon isotope discrimination is highly correlated with plant water use efficiency, and it will have amplitude application prospects in measuring water use efficiency.
