Performance of Phaseolus vulgaris under partial root-zone drying cultivated in a hydrogravitropic system response

Abstract

In the experimental area of the UNALM (Lima-Peru) was evaluated on partial root-zone drying irrigation treatments (RPR300 and RPR500, ml) and full irrigation (RC300 and RC500, ml control), the impact of xylem potential (Psi x) and stomatal conductance (gs) in common bean plants (Phaseolus vulgaris L.) cultivated in systems (pots) of hydrogravitropic response. A randomized complete block design with 12 plants/pots per treatments was used in three replicates. To control the irrigation application and manage to maintain the Psi x nonlethal conditions (
