Efeito do ácido indol butírico e de substratos na clonagem de Cnidoscolus quercifolius Pohl, através de estaquia.

Abstract

Cnidoscolus quercifolius Pohl, is a xerophytic plant that can be used for rehabilitation of degraded areas, feed and food, medicine, sawmill and energy. This work had as objective to evaluate the effect of five IBA concentrations and two substrates on the rooting of faveleira cuttings. This research was made in nursery of the Universidade Federal de Campina Grande (UFCG), Patos-PB Campus. After 180 days of the plantation of the cuttings the variables evaluated were: percentage of live cuttings, percentage of live cuttings with rooting, root dry mass (g), root number and largest root length. There was stimulating effect of the IBA application on the faveleira cuttings, favourable to the rooting formation and promoting an increased in the number of roots. The best results were obtained with IBA concentration 6,0 g/L. Faveleira showed indifference about both substrates (vermiculite and commercial substrate). The best averages were observed in vermiculite substrate for all variables evaluated, but there were no significant differences.
