Tolerance of Two Grafted Tomato Plants (F1 Mongal and Buru Buru; Calinago F1 and Buru Buru) to Fungal Diseases

Abstract

Tomato (Solanum Lycopersicum), a perennial, horticultural crop, can be affected by many pathogens that cause reproductive and vegetative abnormalities. These organisms are often contagious as they can spread rapidly from plant to plant in a field under favourable conditions. Grafting can be an alternative solution to pesticide usage, which can benefit the environment as well as reduce farmers’ expenditure while increasing plant yield. It is a plant propagation technique which involves connecting two plant segments to achieve plant union. Buru Buru, a wild member of the Solanaceae family, was used as a rootstock for common varieties of tomato (F1 Mongal and Calinago F1) to determine their tolerance to diseases under greenhouse conditions. Pathogens were introduced to the plants and they were observed for four weeks. The grafting process required a higher amount of Calinago F1 (45) than the F1 Mongal (33) for successful grafts. Results indicated that there were higher performances by the non-grafted F1 Mongal plants compared to the grafted F1 Mongal plants whereas there were higher performances by the grafted Calinago F1 plants compared to the non-grafted Calinago F1. This study demonstrates that there was a significant difference between the grafted and non-grafted entries of each variety with respect to disease incidence and disease severity.
