Efecto del agua aplicada en las relaciones hídricas y productividad de la vid 'Crimson Seedless'

This study aimed to evaluate the relationship between water and production in 'Crimson Seedless' table grapes, and to establish threshold values for plants water status. Field experiments were carried out, during a three-year period, in the Aconcagua Valley, Chile, at 32º47'S and 70º42'W, in a clay-loamy textured soil. Different irrigation water amounts were applied, between 40 and 100% crop evapotranspiration (Etc). Stem water potential measured at midday (psixmin) and stomatal conductance were closely related to water shortage and yield obtained. Table grape yields decreased in comparison ...
