Irrigation reduction resistance mechanisms in the rapid fruit growth stage of pears (Pyrus communis L.)

Plants adopt physiological defense mechanisms to counteract droughts. In Colombia, there is no information for these mechanisms in pears (Pyrus communis L.), cv. Triunfo de Viena. Therefore, the present study aimed to analyze the hydric conditions of this plant in order to determine if it has develo...
