Responses in the transpiration properties and water use efficiency of leaves from different shoots of Stipa bacailensis to instantaneous changes in the CO_2 concentrations and photosynthetic radiation
贝加尔针茅不同枝条叶片蒸腾特性与水分利用效率对瞬时CO_2和光照变化的响应

Net photosynthetic rate (P_N), transpiration rate (E), stomatal conductance (g_s), intercellular CO_2 concerntration (C_i), vapor pressure deficit at the leaf surface (VPD) and water use efficiency (WUE=P_N/E) of Stipa bacailensis leaves were compared between the vegetative and reproductive shoots under a series of CO_2 concentrations and photosynthetic radiation levels. For the vegetative and reproductive shoots, both P_N and E increased with the increase in CO_2 concentration, but the increase in P_N was ...
