| 英文摘要 | The stable carbon isotope ratios of the desert plant Reaumuria soongorica and the physicochemical properties of soil were analyzed in order to investigate the distribution characteristics of delta C-13 values in this desert plant, and to examine the correlations between delta C-13 values and the soil factors in the major distribution areas in northwestern China. Leaves were collected from the natural distribution areas, at the mean annual precipitation (ranging from 27 to 328 mm), at altitudes from 394 to 1987 m above sea level, at latitudes from 36 degrees N to 45 degrees N and at longitudes from 81 degrees E to 107 degrees E. The correlations between delta C-13 values and the soil factors demonstrated that the foliar delta C-13 values in R. soongorica significantly increased with decreasing soil water content (SWC) and increasing total dissolved solids (TDS) in soil. There were no significant correlations between the delta C-13 values and pH, total nitrogen, soil organic matter (SOM), total phosphorus and effective phosphorus in soil. The results showed that the main soil factors affecting delta C-13 values in the desert halophyte R. soongorica were SWC and TDS. The mean delta C-13 value in R. soongorica was higher than previously reported delta C-13 values in different desert ecosystems. We concluded that the variation in delta C-13 values of R. soongorica was probably caused by stomatal limitation rather than by nutrient-related changes in photosynthetic efficiency. This pattern of delta C-13 values in R. soongorica reinforced that it is a super-halophyte in terms of adaptive strategies to arid environments. (c) 2006 Elsevier Ltd. All rights reserved. |
