Caracterización fenológica acorde a la escala BBCH de dos grupos agronómicos de tomate de árbol (Solanum betaceum Cav.), cultivados en condiciones controladas.

Abstract

This study was conducted to characterize phenologically the tree tomato (Solanum betaceum Cav.) according to two cultivars (purple and elliptical orange Punton), under greenhouse and open field, based on the extended BBCH scale for tree tomato and determining days after sowing, that each of the stages took them to their development began with the principal growth stage 0: Germination, principal growth stage 1a and 1b: leaves development of stem and crown respectively, principal growth stage 2: Formation of side shoots, principal growth stage 3: stem elongation, in which plants grown under controlled conditions, were earlier than those grown in the open field, but from the principal growth stage 5: Emergence of inflorescence, principal growth stage 6: Flowering and principal growth stage 8: Ripening fruit, plants grown in open fields turn out to be more precocious with 420 days, unlike cultivated in later greenhouse with 513 days up to 90% maturation. Key words: Phenology, stages, days, cultivars, vegetative development.
