Evaluación de cuatro técnicas de propagación por injertos en la producción de plantas de cacao criollo (Theobroma cacao L).

Abstract

The present investigation had as general objective: Evaluation of four propagation techniques by grafting in the production of Creole cocoa plants (Theobroma cacao L) in the canton El Carmen-Manabí-Ecuador, for which four treatments were evaluated: The study factor was constituted by applying different types of graft T1 bud graft (i1), T2 graft in t (i2), T3 lateral spike (i3), central spike T4 (i4), implemented in a Complete Random Block Design, concluding than T4 (lateral spike) the best study treatments with the variable number of leaves with 9.9, followed by T3 with 9.45, with a coefficient of variation of (22.65) for the variable height of shoot, the T4 (8.49 followed we obtain central spike T3(6.61) with the coefficient of variation (26.05), for the variable of dead grafts in graft in t (T2) with 7.8 with a coefficient of variation (28.98) Followed by patch grafting (T1) with 7.2, for the variable % of living grafts, lat spike eral (t4) with 11.2 and then T3 (central spike) 7.6, with the coefficient of variation of (19.69). Finally, the economic analysis established that T1, T2, T3 had a rate of return of 83.50, making it economically profitable.
