“…There was no such effect in other rootstocks (Tables 4 and 5), which may have been less vigorous (Schwarz et al 2013). In agreement with the present study, other research has shown that tomato fruit quality is improved by grafting onto potato rootstock (Zhang and Guo 2018), but grafting onto pumpkin and sponge gourd rootstocks does not change the fruit quality of bitter gourd (Tamil and Pugalendhi 2018). The difference in grafting effects on fruit quality may be attributed to the environment and to the specific rootstock-scion combination (Piotto et al 2018).…”

A pot experiment was conducted to determine whether the grafting could improve growth and reduce cadmium (Cd) accumulation of tomato planted in Cd-contaminated soil. 'Zhongyanhong 6' (common tomato) and 'Hongyu F1' (cherry tomato) were grafted onto two varieties of wild eggplant (Solanum torvum and Totosga) and three varieties of tomato ('Dalishengen', 'Banzhen18', and 'Guozhen 1') rootstocks, respectively, and then transplanted in 10 mg kg −1 Cd-contaminated soil for 3 months. The results indicate that except for Totosga, grafting onto other rootstocks resulted in decreased growth and biomass of 'Zhongyanhong 6', but grafting increased growth and biomass of 'Hongyu F1', especially wild eggplant. Compared with ungrafted, grafting on 'Guozhen', Solanum torvum, and Totosga enhanced weight and size of two types of tomato fruits under Cd stress, but only S. torvum improved soluble sugar content and soluble solids of tomato fruits. The Cd content in plants and fruits of 'HongyuF1' grafted on five rootstocks was reduced, and only grafted on 'Banzhen18', Solanum torvum, and Totosga reduced Cd content in plants and fruits of 'Zhongyanhong6', especially two kinds of wild eggplant rootstocks had the most significant reduction in Cd content. Therefore, grafting on different rootstocks had different impacts on two types of tomato under Cd stress, and wild eggplant especially S. torvum is relatively better rootstock for both types of tomato.

“…In comparison, He et al (2009) indicated that no significant differences in photosynthetic activity were found for the same combination of plants, with values between 23 and 25 μmol CO 2 m -2 s -1 . Similar results were obtained by Zhang and Guo (2019), who determined that photosynthesis in tomato scion grafted to a potato rootstock was similar to tomato seed plants (14.4 to 16.4 μmol CO 2 m -2 s -1 ). On the other hand, few studies have been carried out in adult plants (>70 dat).…”

Grafting is an effective approach to improve tomato yield and for tolerance to various abiotic and biotic stresses. This technique consists of using a vigorous or resistant plant (rootstock) to replace the root system of a genotype of economic interest (scion) but susceptible to one or more stress factors. The present work aimed to evaluate the physiological and productive response of a commercial tomato scion grafted on different rootstocks in Colombia’s high-Andean region. For this purpose, a tomato cv. Libertador was grafted on two commercial (“Olimpo” and “Armada”) tomato rootstocks in a randomized complete block experimental design. Four scion×rootstock combinations were evaluated by vigor rootstock, resistant rootstock, self-grafting, and non-grafted plants. Net photosynthesis, transpiration rate, stomatal conductance, water use efficiency, and radiation use efficiency were evaluated during six phenological stages (701, 704, 706, 708, 710, and 712), according to the BBCH scale; while the leaf area index and quantum yield were analyzed in five phenological stages (except 706). The highest values of photosynthesis, stomatal conductance, water and radiation use efficiency were registered in the initial phase of the production stage (701), which tended to decline at the end of the life cycle (712). Transpiration rate was similar throughout the growth cycle. Nevertheless, vigor rootstock presented the lowest photosynthesis rate; it was superior in terms of leaf area index, leaves dry matter, and tomato yield. The quantum yield values of the photosystem II did not indicate photochemical injuries in any of the scion×rootstock combinations. The higher tomato yield was reached in vigor rootstock and was associated with a more significant accumulation of dry matter in the leaf and higher leaf area index.

“…Traits other than sucrose or the galactinol content of tubers can be influenced by grafting. Zhang and Guo [ 36 ] demonstrated that after grafting with tomato, the starch content and vitamin C level in potato tubers were significantly decreased but the reducing sugar content increased. The tuber yield decreased, and several tubers sprouted at harvest, which might be the reason for the reduced starch and elevated reducing sugar concentrations of the tubers.…”

Grafting experiments have shown that photoperiod-dependent induction of tuberisation in potato (Solanum tuberosum L.) is controlled by multiple overlapping signals, including mobile proteins, mRNAs, miRNAs and phytohormones. The effect of vegetative organs and tubers at metabolite level and vice versa, however, has not been studied in detail in potato. To unravel the influence of vegetative organs on the primary polar metabolite content of potato tubers and the effect of tuberisation on the metabolite content of leaves grafting experiments were carried out. Two potato cultivars, Hópehely (HP) and White Lady (WL), were homo- and hetero-grafted, and the effects of grafting were investigated in comparison to non-grafted controls. Non-targeted metabolite analysis using gas chromatography-mass spectrometry showed that the major difference between HP and WL tubers is in sucrose concentration. The sucrose level was higher in HP than in WL tubers and was not changed by grafting, suggesting that the sucrose concentration of tubers is genetically determined. The galactinol level was 8-fold higher in the WL leaves than in the HP leaves and, unlike the sucrose concentration of tubers, was altered by grafting. A positive correlation between the growth rate of the leaves and the time of tuber initiation was detected. The time of tuber initiation was delayed in the WL rootstocks by HP scions and shortened in the HP rootstocks by WL scions, supporting the previous finding that tuberisation is triggered by source-derived mobile signals.
