摘要

This study aimed to evaluate the effect of biostimulante Promalin? promoting sprouting in root cuttings of blackberry (Rubus spp.) cv. Brazos. The experiment was conducted from January to March 2010, with a completely randomized design with five concentrations of biostimulant, as solution: T1= 0 mg L-1, T2= 10 mg L-1, T3= 20 mg L-1, T4= 40 mg L-1 and T5= 80 mg L-1 with the root cuttings dipped in these solutions for 12 hours and seven replications, and the plot compose by ten root cuttings. After 75 days were examined: the emergence of shoots, number of sprouting, shoot number, leaf number, length of main stem and survival percentage of the shoots, besides the analysis of soluble carbohydrates. Gradual evolution has occurred over time in the emergence of the shoots, beginning in approximately seven days after planting. The highest concentrations of Promalin? inhibited the sprouting of root cuttings and the growth characteristics of these shoots, the best results were achieved without the application of the product.
