Relationships Between Carbon Dioxide Transfer Resistances and Some Physiological and Anatomical Featllular resistance (r. = r. + r.) presents the most difficult interpretational problems. The separation of r. into a transport (r.) and carboxylation (r.) component is dependent upon the model used. For example, the high r./r. ratio observed in C. plants may be partly due to the form of the equation

The Basis of Expression of Leaf Photosynthetic Activities affect its photosynthetic performance. In order to examine this problem a simple analysis has been made of the role of leaf structure in determining the rates of transfer of carbon dioxide from the air to the assimilatory sites within the leaf..The analysis is supported by published experimental da

Control of Photorespiration in Soybean and Maizexylase. Carbon dioxide and oxygen compete for RuDP at the carboxylase. High CO. and low O. favor carboxylation of RuDP to 3-phosphoglycerate, thereby promoting photosynthesis. Low CO. and high O. concentrations favor oxygenation of RuDP to P-glycolate, thereby promoting photorespiration. In maize, t

Problems in Building Computer Models for Photosynthesis and Respiration status of the carbohydrate reserve. We discuss some of our efforts to measure components of these equations, emphasizing difficulties in estimating gross photosynthesis. We need quantitative estimates of respiration in the light caused by the accumulation of photosynthate, to add to measurements of

Effect of Growth Temperature on Photosynthetic and Photo-Respiratory Activity in Tall Fescue processes is less well documented. In the present study the degree of temperature adaptation on plant growth in relation to NCE and photo-respiratorv activity and selected . enzyme activities has been determined in Tall Fescue grown at 10° and 25°. Different optima for NCE have been shown to be rel
