Abstract


The propagation by cutting comes as an alternative to guarantee the production of uniform and genetically homogeneous seedlings. Cutting of Annona squamosa(L.), Annona muricata(L.) and Atemoya Annona cherimolax Annona squamosa(L.) were collected at twotimes of the year, 15cm long, with two pairs of leaves cut in half. The cuttings were treated by immersing their base for 5 seconds in indolbutiric acid and naphthaleneacetic acid solutions at concentrations of 0, 0,25%, 0,50%, 0,75% and 1%, and then werepacked in styrofoam polyethylene trays containing mix of substrate, maintained for 120 days under intermittent misting. Indolbutyric acid and naphthaleneacetic acid increase the rooting percentage, number and root length at concentrations of 0.50% to 0.75% respectively. Thefor the best season, highlights the summer.
