Uso de promotores de enraizamento na produção de mudas de videira

Abstract

The method of propagating vines by table grafting is an increasing practice that offers higher quality and healthier seedlings. The objective of this work was to evaluate different products, being them development stimulants, in order to obtain better rooting quality and homogeneity in grapevine seedlings grafted by the table grafting method. The test was carried out in the seedling nursery located in Águas Claras – Viamão. Grafted cuttings composed of Paulsen 1103 rootstock and common Isabel copa variety were used. The following products were used, Ribumin®, which acts as a soil conditioner, the Viva® product, which is a compound of polysaccharides, purified humic acids, amino acids and proteins, and the Fortific® product, which acts as a strength enhancer and inducer. The treatments performed were: Witness (T), Ribumin® (T1), Viva® (T2), Fortific® (T3), Ribumin® + Fortific® (T4) and Viva® + Fortific® (T5). In the respective dosages, Ribumin® 300 g/m2, Viva® 500 ml/100L, Fortific® 3L/ha. The project evaluated the rooting percentage and root architecture through number, length and root weight of the seedlings of each treatment in relation to the control. A randomized design with six treatments and three replications was used. Results were presented as means and standard deviations. There was no statistical difference in the parameters evaluated and we suggest that a new experiment with a greater number of repetitions be carried out to obtain more conclusive results.
