Description
Summary:Besides that, rooting response also varies according to the clone genotype. In Brazil, the species Acacia mearnsii De Wildeman, known as black wattle, is economically important in forest sector mainly for tannin extraction. [...]vegetative propagation is an alternative to obtain genetically superior individuals. Long minicuttings may be more susceptive to dehydration, once they demand more water to supply all the tissue exposed to the environment (Lima et al., 2006). [...]in order to improve vegetative propagation techniques of black wattle, the objective was to determine the ideal size to induce rooting in minicuttings; if the presence, absence or leaves size influences in the rooting process and which stem cutting position is more effective to produce seedlings of black wattle commercial clones. (2017) observed in mulberry that intermediate and basal cuttings present significant increase in aerial part better than apical cuttings. Besides that, IBA application in rising doses until 2000 mg L-1 were related to decrease of sprout and rooting.
