Abstract
The possibility of applying different methods in grafting vegetable plants, give the possibility to improve the fruit quality. Genotypes of Solanum lycopersicum L. have been grafted on tomato rootstocks distinctively, and the impact of the rootstock on several important fruit quality parameters has been studied. The results obtained from the physicochemical analysis demonstrated that the maximum content of titratable acidity was observed in the control hybrids. The variants V-2 (Abellus+Emperador), V-5 (Lilos+Emperador), V-6 (Lilos+Maxifort) and hybrid V-7 (Beril) had a higher sugar and acid content. Results of evaluated were showed in many parameters in favour of variants. The following morphometric characteristics have been also assessed. The average number of clusters per plant of the non-grafted plant of the V-7 (Beril F1) hybrid was 12.6 compared with 14.3 (V-8) and 14.4 (V-9) pieces of variants. Overall, these results have shown the effectiveness of grafting in terms of plant productivity and the improvement of tomato fruit quality, which are of particular importance, because grafting is a quick and effective alternative to achieve these goals.
