Conteúdo: | A method was developed to consistently induce floral differentiation in mature `Tommy Atkins' mangop trees by air-layering branches of adult, field trees. Rooting of firdled branches was induced within 12 weeks with the aid of 2% naphthaleneacetic acid in lanolin paste. Rooted air-layers were pruned and completely defoliated upon potting to regenerate the canopies. Mature, fully-expanded vegetative shoots were obtained within 100 weeks of pruning. Trees with developmentally uniform canopies were exposed to a chilling treatment of 18/10oC (day/night temperature, 12-h photoperiod). Defoliation of shoot tips stimulated initiation of apical buds. Bud break of nearly all stimulated buds occurred after 7 to 8 weeks of chilling. More than 80% of buds differentiated floral primordia. Bud meristematic activity during chilling was required for floral differentiation. Chilling induced flowering of containized trees regardless of time of the year.
