| Sumario: | Knowledge of different aspects of vegetative and floral development of Choquette and Booth-8 avocados is necessary to improve their productivity in the avocado producing region of San Blas, Nayarit, Mexico. This research was undertaken from 2004-2006 in one Choquette and one Booth-8 orchard cultivated under rainfed conditions (annual rain= 1 453 mm) in the warm and subhumid climate (average annual temp.= 25.2 ºC) of Jalcocotan, San Blas, Mexico. The objectives were: a) to determine the occurrence and intensity of vegetative growth fl ushes, b) to quantify the contribution of each vegetative fl ush to bloom, and c) to assess the evolution of fl oral development for Choquette and Booth-8 avocados. Three vegetative fl ushes occurred in Choquette: spring, summer, and fall; the spring fl ush had the greatest intensity. Booth-8 only had two vegetative fl ushes of similar intensity, spring and summer. Choquette spring vegetative fl ush had the highest contribution to bloom (57%), followed by summer (39%) and fall (14%) flushes. In Booth-8, the greatest contribution to bloom corresponded to summer vegetative fl ush (51%). Shoot age (spring or summer) had no effect on the date when both type of shoots attained anthesis in Choquette. The complete fl oral development process, from closed and pointed vegetative bud to anthesis, in Choquette spring fl ush shoots required 365 days. Summer shoots of Choquette and Booth-8 needed 255 days. |
