| 英文摘要 | The effect of enhanced ultraviolet-B radiation (280-315 nm) and water stress on water consumption, instantaneous water use efficiency (WUEi), season-long water use efficiency (WUEs) and leaf stable carbon isotope composition (delta(13)C) of three spring wheat Cultivars (Triticum aestivum L) was investigated under held conditions. The relationship between WUEi and WUEs with delta(13)C was analyzed. Compared with the control, enhanced UV-B or water stress alone or in combination led to lower water use, and soil drought had a stronger influence oil water use than Supplementary UV-B irradiance. Soil drought increased the instantaneous water use efficiency (WUEi) and UV-B radiation decreased it significantly in comparison to the control. The combination of UV-B and water stress resulted in increased/reduced or no changed WUEi, different with change. Season-long water use efficiency (WUEs) showed the same trend as observed with WUEi under the conditions of UV-B radiation and water stress, except that no significant difference between control and drought in cv. Heshangtou. WUEs under the combined conditions of UV-B and water stress, was clearly increased in every cultivar. Enhanced UV-B radiation and the combination with drought led to negative foliar stable carbon isotope composition (delta(13)C) and drought alone resulted in a positive Value for delta(13)C. Tile relationship between foliar stable carbon isotope composition and instantaneous water use efficiency was not significant. Nevertheless, a positive correlation with, (delta(13)C) against season-long water use efficiency was observed. The results indicated that delta(13)C can be a useable parameter for selecting a crop genotype having higher water use efficiency. (C) 2008 Elsevier B.V. All rights reserved. |
