Effects of salt stress on plant growth, abscisic acid and salicylic acid in own-rooted cultivars of Vitis vinifera L.

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