Changes Induced by Low Oxygen Concentration in Photosynthetic and Respiratory CO2 Exchange in Phosphate-Deficient Bean Leaves

Abstract

Effect of phosphorus deficiency on photosynthetic and respiratory CO2 exchanges were analysed in primary leaves of 2-week-old bean (Phaseolus vulgaris L. cv. Golden Saxa) plants under non-photorespiratory (2 % O2) and photorespiratory (21 % O2) conditions. Low P decreased maximum net photosynthetic rate (PNmax) and increased the time necessary to reach it… (More)
