Characterization of Water Deficit Effects on Chloroplast Photosynthetic Potential

水分亏缺对叶绿体光合势的影响特征：这项研究继续描述叶片中的水分亏缺如何抑制叶绿体光合势，并建议确定调节这种抑制程度的内源细胞机制。将检测叶绿体对脱水外渗势的反应和对叶片水分亏缺的原位反应。从这项研究中获得的信息应该会增加我们对非气孔介导的水分亏缺对光合作用影响的因素的理解。在水分胁迫条件下，非气孔效应似乎是作物生长的主要限制因素。

Characterization of Water Deficit Effects on Chloroplast Photosynthetic Potential: This research continues the characterization of how water deficits in leaves inhibit chloroplast photosynthetic potential and proposes to identify endogenous cellular mechanisms that modulate the severity of this inhibition. The chloroplast response in vitro to dehydrating external osmotic potentials and in situ to leaf water deficits will be examined. The information obtained from this research should increase our understanding of the factors involved in non-stomatal-mediated water deficit effects on photosynthesis. Non-stomatal effects appear to be the major limiting effects on crop growth under- water stress conditions.
