Evaluación de tres métodos de polinización artificial en clones de cacao (Theobroma cacao L.) CCN-51

Abstract: Evaluación de tres métodos de polinización artificial en clones de cacao (Theobroma cacao L.) CCN-51 RESUMENEl objetivo fue evaluar tres métodos de polinización artificial en cacao clonal CCN-51 de siete años de edad, en la Hacienda San Antonio, ubicada en el km 16 de la vía Quevedo-El Empalme. Fueron evaluadas las variables número de flores fecundadas, número frutos sanos cosechados, peso total de fruto (g), número de semillas y rendimiento estimado kg ha -1 . Los tratamientos fueron: T0 = Control polinizació… Show more

“…The biology of cacao mainly responds to climatic events such as rain and air temperature, similar to other plant species (Lesica & Kittelson, 2010). Meteorological conditions play an essential role in the production of pollen in T. cacao and are directly related to the variety of the phenological states and reproductive functions of the species (Dubón, 2015;Torres-Gutiérrez, 2012;Vargas et al, 2005;Vera-Chang et al, 2016). Based on research conducted in Ecuador, there is a positive relationship between the deposition of pollen to stigmas and climatic variables such as maximum air temperature (r = 0.46), precipitation (r = 0.33), relative humidity (r = 0.27), and wind speed (r = 0.29) (Mena-Montoya et al, 2020).…”
