Abstract:
In this study, we examine about how tomatoes behave when grafted on different rootstocks by measuring the amount of change in the qualitative composition of tomato grafts using various rootstocks, scions, and grafting methods. Two tomato hybrids (Yuvraj and Suraj) were used as scions, and five different cultivars (Pant T3, Solanum lycopersicum var. cerasiforme, Solanum torvum, VNR Solmel Brinjal and VNR Garcia chilli) were used as rootstocks and they were grafted using Splice grafting methods. Analyses were performed for reducing sugar percent, non-reducing sugar percent, total sugar percent, TSS, ascorbic acid content, titrable acidity, lycopene content, firmness and pH value. The biochemical compositions were significantly affected by different rootstock and tomato scions. Pant T3 had the highest reducing sugar percent, non-reducing sugar percent and total sugar percent whereas Solanum lycopersicon var. cerasiforme had the highest TSS, ascorbic acid content, titrable acidity, lycopene content, firmness and pH value. Yuvraj was performed best among both scions. Among all the combinations, Yuvraj grafted onto Pant T3 had highest reducing sugar percent, non-reducing sugar percent, total sugar percent; Yuvraj grafted onto Solanum torvum had maximum firmness; Yuvraj grafted onto Solanum lycopersicon var. cerasiforme had highest TSS, ascorbic acid content, titrable acidity, lycopene content and pH value. The interactive effect of scion-rootstock combinations of tomato was found more effective than control for all growth parameters under study. The results of this study suggest that the grafting of tomato on tomato and brinjal rootstock may be a good strategy for enhancing the biochemical composition of tomato.
