Abstract  

Stoichiometric traits of C, N, P for desert shrub Zygophyllum xanthoxylum leaves with changes in leaf size were observed. The results showed that with the values of individual leaf mass (ILM), individual leaf area (ILA) and leaf mass per area (LMA) increasing, leaf C, N and P contents decreased rapidly and then tended to be stable, while both leaf C∶N and C∶P increased gradually, N∶P increased firstly and then tended to be stable. In our study, the coefficient of variation(CV) for individual leaf mass was 55.44%, while the CV for leaf C, N and P content, C∶N, C∶P and N∶P were less than 25%, and the order was: P(22.6%)>N(15.21%)>N∶P(14.67%)>C∶P(13.30%)>C(12.18%)>C∶N(8.81%).

Key words:  Zygophyllum xanthoxylum      leaf size      ecological stoichiometry
