Grafting raises the salt tolerance of tomato through limiting the transport of sodium and chloride to the shoot

Abstract: With the aim of determining whether grafting could improve salinity tolerance of tomato (Lycopersicon esculentum Mill.), and what characteristics of the rootstock were required to increase the salt tolerance of the shoot, a commercial tomato hybrid (cv. Jaguar) was grafted onto the roots of several tomato genotypes with different potentials to exclude saline ions. The rootstock effect was assessed by growing plants at different NaCl concentrations (0, 25, 50, and 75 mM NaCl) under greenhouse conditions, and by… Show more

“…In particular, increased salinity tolerance improves fruit yield of grafted tomato [8] [14]. Higher yield of grafted plants has been also observed in watermelon (Citrullus lanatus) [15] and in melon (Cucumismelo) [16] [17].…”

“…Grafting is widely established in agriculture and provides practical advantages for vegetable production by increasing resistance to soilborne pathogens [1]- [4], tolerance to low root-zone temperatures [5]- [7], salinity tolerance [8]- [10], and endogenous hormone production [11]- [13]. In particular, increased salinity tolerance improves fruit yield of grafted tomato [8] [14].…”

“…Tomato and melon are the two commonest herbaceous species in which the grafting practice has been efficiently applied to obtain salt-tolerant plants (Estañ et al, 2005, Edelstein et al, 2011, Orsini et al, 2013. In melon, the favorable effects of grafting on plant growth cannot be ascribed to a more efficient exclusion of Na + or enhanced nutrient uptake but they were associated with a more efficient control of stomatal functions (changes in stomatal index and water relations), which may indicate that the rootstock may alter hormonal signalling between root and shoot (Orsini et al, 2013).…”

“…This increased tolerance of grafted plants is generally associated with their capacity to exclude or retain and/or accumulate toxic ions, Na + and Cl -in rootstock roots, thus limiting their transport to leaves rather than through the synthesis of osmotically active metabolites or the induction of antioxidant systems [6][7][8].…”
