Description:

Two cultivars of bean, Tacarigua and VUL 73-401 were subjected to two levels of water stress followed by rewatering. During the water deficit period, water potential (Ψ№), osmotic potential (Ψ5) and relative water content (rwc) decreased with an associated decrease of ribulose-l,5-bisphosphate carboxylase activity (RuBPC), protein and chlorophyll (Chi) contents. In cv. Tacarigua, the % decrease of RuBPC was less marked than that of protein content. There was a significant correlation among the components of leaf water status and the measured photosynthetic parameters. Groups of water stressed plants were rewatered, when reached -1.25 to -1.60 MPa. During the recovering period all components of leaf water status increased and reached the control values on the 6th day after rewatering. Chi content increased above the control values. Protein content and RuBPC activity also increased during the rewatering period, but the % increases in protein content and RuBPCase activity were not parallel.
