摘要：
Net photosynthesis, transpiration, and resistances to CO2 and water vapour transfer of two cultivars of each of four types (Triticum durum, Triticum aestivum. hexaploid Triticale, octaploid Triticale) were analysed. Hexaploid triticales have the highest net photosynthesis and the best water efficiency. Water efficiency was defined by the CER/transpiration ratio measured under saturating irradiance corresponding to full stomatal opening. Cultivated bread and durum wheat cultivars (Capitole, Champlein, Bidi 17) are characterised by a low CER associated with a large flag leaf area and a high mesophyll resistance. There is a close correlation between CER., flag leaf area, mesophyll resistance and total chlorophyll content. © 1979 H. Veenman En Zonen B.V.
