Effect of Water Supply and Defoliation on Photosynthesis, Transpiration and Yield of Soybean
Defoliation Glycine max Leaf water potential Photosynthesis Stomatal conductance
2009/8/4
While increasing leaf area increases CO2-fixing ability of plants, it also increases transpiration and may cause water deficit within a plant. This study was conducted in order to analyze the combined...
Root Morphological Plasticity for Heterogeneous Phosphorus Supply in Zea mays L.
Nutrient patches Phenotypic plasticity Phosphorus uptake Resource foraging Root proliferation Soil heterogeneity Zea mays
2009/7/24
The morphological plasticity of roots in nutrient-enriched patches of soil is regarded as an adaptive response in plants, but its functional efficiency is still debatable. We examined whether the effi...
