Abstract:
In this study, we examine about how tomatoes behave when grafted on potatoes by measuring the amount of change in the qualitative composition of tomato grafts using various rootstocks, scions, and grafting methods. Three tomato hybrids (Lakshmi, Aviral, and Yuvraj) were used as scions, and two potato cultivars (Kufri Pukhraj and Kufri Jyoti) were used as rootstocks and they were grafted using two different grafting methods: splice and cleft. Analysis were performed for ascorbic acid content, acidity percent, reducing sugar percent, non-reducing sugar percent, and total sugar percent. The biochemical compositions were significantly affected by potato rootstock, tomato scions, and grafting methods. Yuvraj used as scion had the highest ascorbic acid content, acidity percent, reducing sugar percent, non-reducing sugar percent, and total sugar percent, and Kufri Pukhraj had the highest ascorbic acid content, acidity percent and the maximum reducing sugar percent, non-reducing sugar percent, and total sugar percent found in Kufri Jyoti. Splice method of grafting was found best on among all the parameters than cleft method of grafting. The results of this study suggest that the grafting of tomato on potato may be a good strategy for enhancing the biochemical composition of tomato.
