Propagação de videira pelos sistemas hidropônico e convencional

Abstract

Brazil is one of a major producers of fruits in the world, occupying a prominent place in the production of grapes, wines, juices and other derivatives. In the formation of this new fruit orchards still dominates the budding field that is more costly to the producer, and take about a year longer for the start of production. New techniques for the production of seedlings were sought by growers and nurserymen, aiming to reduce the deployment costs of an orchard, the most common of them is the table grafting, due to high yields achieved. However, as the demand has been high in recent years Brazil has imported seedlings, to meet the gap in this sector. Aiming to verify the feasibility of the production of grafted vine in the hydroponic system were installed experiments seeking to verify the use of IBA and Zn cofactor in the rooting of vine rootstock, and compare the conventional and hydroponic production systems related to different grafting methods. It was concluded that the system is feasible in hydroponic production of rootstock 'Riparia the Traviú'. The conventional system was more efficient for the success of the graft, and the cleft grafting was the best method of grafting. Although there was no significant difference in root length and number of the different treatments, there is a tendency of the dry mass in the roots of the cuttings treated with Zn to be greater than in the untreated.
