Abstract/Contents: | "In order to reveal the cause of water use efficiency (WUE) difference, water and photosynthetic characteristics of Tall Fescue genetic materials with different WUE were studied in pot experiment. Results showed that, high WUE accessions had favourable water relation and were more drought-resistant, meanwhile, their stomatal conductance were lower and WUE were higher. No net photosynthetic rate difference was existed in high and low WUE accessions. The radical cause of WUE difference attributed to mesophylic photosynthetic capacity. Specific leaf weight, chlorophyll content (expressed in area) and internal CO2 concentration Ci could be used as valid indexes for WUE evaluation." |
