“Efecto de la disponibilidad del agua en el suelo, sobre el control estomático de clones de cacao (Theobroma cacao L.)”

Abstract

THE PRESENT INVESTIGATION WAS CARRIED OUT IN THE LA TEODOMIRA EXPERIMENTAL STATION OF THE TECHNICAL UNIVERSITY OF MANABÍ FACULTY OF AGRONOMIC ENGINEERING, LOCATED IN THE LODANA PARISH OF THE SANTA ANA CANTON, THE OBJECTIVE OF THE PRESENT INVESTIGATION WAS TO EVALUATE THE EFFECT OF THE AVAILABILITY OF WATER IN THE SOIL , ON THE STOMATAL CONTROL IN PLANTS OF FOUR COCOA CLONES (THEOBROMA CACAO L.) CCN51- EET103- EET-575- EET-576 UNDER SEMI-CONTROLLED CONDITIONS. A COMPLETELY RANDOMIZED DIVIDED PLOTS DESIGN WITH FOUR WATER LEVELS 100%, 80%, 60%, 40% OF THE REFERENCE EVAPOTRANSPIRATION (ET0) WAS ESTABLISHED, USING CROWAT DE PENMAN MONTEITH SOFTWARE DAILY ACCORDING TO FOUR KC1 CROP COEFFICIENTS , KC 0.80, KC 0.60, KC 0.40 FOUR CLONES AND FOUR REPETITIONS. THE VARIABLES IN THE HYDRIC BEHAVIOR EVALUATED WERE: STOMATAL INDEX, STOMATAL DENSITY AND STOMATAL CONDUCTANCE.
