Abstract

Field experiments were conducted at the Teaching and Research farm of the University of Ghana Forest and Horticultural Crop Research Centre (FOHCREC), Okumaning-Kade to investigate the effect of grafting on growth, yield, disease resistance and fruit quality of tomatoes grafted onto two different African eggplant rootstocks. Two commercial tomato varieties ('Tropimech' and 'Roma') were used as scions and two African eggplant varieties ('Aworoworo' and 'Green') were used as rootstocks. The scion/rootstock combinations or treatments were 'Roma/Green', 'Tropimech/Green', 'Roma/Aworoworo', 'Tropimech/Aworoworo', 'Roma/Roma', 'Tropimech/Tropimech', and Roma non-grafted (control) and Tropimech nongrafted (control). The results indicated that, grafted tomatoes on African eggplant rootstocks performed better in terms of growth, yield, earliness, disease incidence and shelf life than non-grafted or control plants. Pooled mean data indicated significant differences in terms of percent fruit set, fruit number and weight among the treatments. Percent fruit set was higher for tomato on Africa eggplant (67.9) compared to the self grafted (58.7) and the control (52.6). Fruit number/plant and yield of tomato on the African eggplant was 16.2 and 1120.7g/plant compared to the control (10.8 and 916g/plant) while the self grafted had 13.2 and 1064.9g/plant, respectively. The shelf life of grafted tomatoes onto egg plant was significantly higher (25.4 days) compared to control (13.6 days). Grafting did not significantly affect Brix (%), pH and acidity of tomato. Grafted plants significantly recorded low disease incidence compared to non-grafted ones. The study indicated that the use of grafting on eggplant in the humid forest zone of Ghana can boost tomato production considerably.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
