Partitioning and Utilization of Apparent Photosynthate by Soybean (Glycine Max (L.) Merr.) Relative to Nitrogen Source: Nitrogen vs Nitrate
Nodulated and non-nodulated (not inoculated) soybeans (cv. Wells) were grown in controlled environments with N(,2) or non-limiting levels of NO(,3)('-) respectively serving as sole source of nitrogen. Plants were evaluated on the basis of whole plant efficiency of apparent photosynthate utilization relative to nitrogen assimilation (expressed as the ratio of moles of carbon respired by the whole plant to the moles of nitrogen incoporated into plant material). The efficiency of the N(,2)-fixing plants was compared with that of the nitrate-suplied plants on the basis of plant age and plant size.
