Aim of study: In most areas of vineyards worldwide, cultivars are frequently grafted on specific rootstocks to avoid Daktulosphaira vitifoliae pest attack. Nevertheless, the absence of this pest in Canary Islands allowed the chance to conserve and cultivate traditional or new own-rooted genotypes without the requirement of the rootstocks. To investigate the responses of own-rooted genotypes of Vitis vinifera L. to salt stress conditions, ‘Castellana Negra’ (‘CN’) and ‘Negramoll’ (‘Ne’) were used with the aim to characterize their morphological and physiological responses.Area of study: Canary Islands, Spain.Material and methods: The effects of NaCl stress on growth, abscisic acid (ABA), salicylic acid (SA) and proline were assessed in ‘CN’ and ‘Ne’ under greenhouse conditions.Main results: In ‘CN’, the decrease of leaf number in stressed plants was lower and started eleven days later than in ‘Ne’. Salt stress also reduced stomatal conductance (gs), although such decrease took place earlier in ‘CN’ than in ‘Ne’. ABA and SA concentrations in ‘CN’ leaves were 2-fold higher than those of ‘Ne’. Salt stress increased leaf ABA and SA content in both genotypes, compared to control. In conclusion, ABA and SA appear to be involved in grapevines responses to salinity and suggest that exogenous SA could be useful to mitigate the stress impacts.Research highlights: ‘CN’ exhibited a better response than ‘Ne’ through the delay of salt injury establishment, and the dissimilar responses between ‘CN’ and ‘Ne’ seem to be associated to the higher accumulation of ABA and SA under salt stress.
