“…'Beaufort', 'He-Man', and 'Resistar' grown under low to moderate salt-stress conditions had enhanced titratable acidity (TA), total soluble solids (TSS), and ascorbic acid concentrations in fruit, but grafting and rootstock choice had no effect on any quality characteristics. Di Gioia et al [14] reported similar results: fruit contents of TSS, TA, and dry matter were unaffected by grafting at any salinity level.…”

“…Grafted tomatoes may yield 30% more marketable fruit per plant, but their contents of vitamin C and total phenolics may decrease significantly as a result of grafting [13]. Di Gioia et al [14] found that vitamin C content decreased by 14-20% in the fruit of tomato plants grafted onto 'Beaufort F1' and 'Maxifort F1' compared with fruit of ungrafted plants. Savvas et al [15] investigated the effects on fruit yield and quality of grafting a commercial tomato hybrid onto three commercial tomato rootstocks grown in a recirculating hydroponic system.…”

The aim of this research was to evaluate postharvest cherry tomato (Solanum lycopersicum (L.) Mill.) yield and fruit quality as affected by grafting and irrigation water quality in the desert region of Israel. Tomato plants (scion cv. Lorka) were grafted onto 3 commercial tomato rootstocks (Resistar, Beaufort and TRS2) and were irrigated with 2 water qualities: fresh water (electrical conductivity (EC)-1.6 dS m−1) and salty water (EC-4.0 dS m−1). Fresh water significantly increased fruit yield by an average of 17% and fruit size, regardless of plant grafting and rootstock, but there were no significant differences in fruit size between the water treatments. However, salty water, but not grafting, significantly improved several quality parameters of fruit stored for 12 d at 12 °C followed by 2 d at 20 °C in simulated sea transport of produce from Israel to Europe and marketing. Fruit harvested from plants irrigated with salty water showed higher sweetness, sourness and, especially, better general taste, and significantly reduced off-flavor, compared with those irrigated with fresh water. The combination of ‘Lorka’ on ‘Resistar’ rootstock and resulted in the best external, internal, and sensory quality parameters at the end of storability and marketing simulation, while the lowest-quality parameters were in fruit harvested from ‘Lorka’ on ‘Beaufort’ rootstock.

“…), in the present study, we hypothesised that grafting tomato onto vigorous interspecific hybrids ( S. lycopersicum × S. habrochaites ), which have been demonstrated to be tolerant to salinity stress (Di Gioia et al . ), might raise tomato tolerance to excess B. Therefore, we investigated how grafted, self‐grafted and non‐grafted tomato plants, grown in hydroponic culture, respond to excess B (up to 15 mg·l −1 ) in terms of growth, B uptake and its partitioning in plant tissues.…”

Grafting response to excess boron and expression analysis of genes coding boron transporters in tomato

et al. 2017

Boron (B) is essential for plant growth, however its excess in soil and/or in irrigation water can severely compromise plant growth and yield. The goal of this work was to determine whether grafting onto 'Arnold', a commercial interspecific hybrid (Solanum lycopersicum × S. habrochaites) rootstock, which in a previous study was found to be tolerant to salt stress, could improve tomato (S. lycopersicum L. 'Ikram') tolerance to excess B, and whether this effect is associated with an exclusion mechanism. Non-grafted, self-grafted and grafted plants were hydroponically grown in a greenhouse with B concentration in the nutrient solution of 0.27 (control), 5, 10 and 15 mg·l . A transcription analysis was carried out on SlNIP5 and SlBOR1 genes, which encode putative B transporters. Grafting 'Ikram' onto 'Arnold' rootstock reduced B concentration in leaf tissue of plants exposed to B concentrations of 10-15 mg·l . At high B levels, SlNIP5 was down-regulated in all grafting combinations, while SlBOR1 was down-regulated only in the roots of plants grafted onto 'Arnold'. We conclude that grafting the susceptible tomato cultivar 'Ikram' onto the commercial rootstock 'Arnold' improved tolerance to excess B by reducing expression of genes encoding for B transporters at the root level, thus partially reducing the root uptake of B and its accumulation in the shoot.

In the present study, tomato (grafted and nongrafted) was grown in the soil under net-house cover by pearl and red nets (50% shade index) or un-shade condition (open field-control). Commercial tomato cultivars ('Optima F1' and 'Big Beef F1') were used to determine whether grafting (Maxifort rootstock) could prevent decrease of fruit weight and quality under light stress conditions. Nongrafted 'Optima F1' and 'Big Beef F1' was used as a control plants. Total yield of grafted plants was higher (51.0%) than non-grafted only in 'Optima F1'. Shading maintained 30-40% higher marketable yield (reduced the amount of pysiological disorders) than plants from non-shaded conditions in both cultivars. Among the fruit components, lycopene, ascorbic acid, phenols, total sugar and citric acids concentrations and ratio of sugar and acid content were examined. In every case the values of these parameters were lower in the fruits from grafted plants than those from ungrafted ones, meaning that the increase of the yield quantity caused the decrease of main fruit components. The decrease of bioactive compounds had a similar trend and intensity, though some inter-color shade variation was observed. Fruits from shading plants under red nets obtained highest lycopene content in both grafted and non-grafted plants.
