Agronomic performance and incidence of diseases in tomato grafted plants (solanum lycopersicum l.)

To determine the performance of tomato, grafted on tomato native from Mexico, a study in Valle de Apatzingan Michoacan, Mexico in 2008 was established. As rootstock ecotypes of tomato Solanum lyoopersicum L. variety oeraszforme (Tinguaraque) were used, and as graft the cultivar Toro® was used. A randomized complete block design with 13 treatments was performed: six grafts of tomato on Tinguaraque, six Tinguaraque and one control (tomato). Specifically in grafts and tomato (six treatments) the following characteristics were evaluated: plant height, diameter of stem, number of flower clusters,height to the first floral cluster, weight, size and yield of fruits by plant; moreover in all treatments (13 treatments) pH, soluble solids and moisture were registered in fruits; also the disease plant incidence was evaluated. Significant differences were found for height, diameter, flower clusters and fruit size, which grafts showed higher values in contrast to tomato. Among the three registered diseases (damping off, Alternaria-Fusarium complex and geminivirus), only damping off had statistical differences, where the grafts presented lower incidence. By comparing the values of characteristics of fruits, Tinguaraque and tomato presented particular values, and these did not influence in the graft. It was concluded that the tomato graft showed potential benefit in crop management, without devalue the characteristics of plant and fruit, nor the yield; for grafting, the incidence of “damping off’ with respect to the tomato was reduced.
