Scion and Rootstock Differently Influence Growth, Yield and Quality Characteristics of Cherry Tomato

Grafting is a valuable tool for managing problems of tomato soil-borne pathogens and pests, but often generates unpredictable effects on crop yield and product quality.

Description
Summary:Grafting is a valuable tool for managing problems of tomato soil-borne pathogens and pests, but often generates unpredictable effects on crop yield and product quality. To observe these rootstocks-induced changes, experimental designs including many rootstock-scion combinations are required. To this end, a greenhouse experiment was conducted on 63 graft combinations, involving seven cherry tomato scions grouped in large, medium and small-fruited, and eight rootstocks with different genetic backgrounds (crosses between and or or , plus an intraspecific hybrid), using ungrafted controls. The response of the graft partners was firstly analyzed individually using the environmental variance (σ ), then by grouping them by classes. When analyzed individually, the scion genotype influenced fruit , , shape index, total soluble solids (TSS) and its ratio with tritatable acidity (TSS/TA), whereas plant growth and yield were unpredictable. After clustering the graft partners, some of these responses were attributable to the imposed classes. The -derived hybrids maximized plant biomass, unlike the ones. Both classes reduced fruit biomass in small- and medium-fruited scions (by 11 and 14%, respectively). The and hybrids reduced and TSS, whereas promoted TA. L-ascorbic acid was reduced by grafting (from -23 to -45%), in the group too, indicating, even in low vigor rootstocks, a dilution effect worsening this nutraceutical trait of tomatoes.
