Özet:

 Salt stress has become an increasingly serious threat to viticulture due to global climate change and a lack of irrigation resources. Salt accumulated in the soil causes ionic imbalance, osmotic stress and consequently oxidative stress in grapevines, negatively affecting the morphological, physiological and biochemical processes of the plant. The defense responses developed by the plant against these stress conditions may differ largely depending on the rootstock material used and the supporting external applications. In this context, in the study, two different levels of salt stress Salt 1: 150 mM, Salt 2: 150 mM150 mM were applied on three different rootstocks Ownroot, 1103P and 140Ru of potted Öküzgözü Vitis vinifera L. and the effects of biostimulants Saccharomyces cerevisiae and Ascophyllum nodosum on the antioxidant system were investigated under salt stress conditions in 2023 vegetation period. The results showed that rootstocks developed different responses to salt stress and the severity of these responses varied depending on the type of treatment. Total phenolic compound level increased the most in high salt stress and biostimulants balanced this stress. Antioxidant activity, similar to total phenolic compounds and as expected, reached the maximum level at high salt stress and both parameters were highest on the 1103P rootstock. SOD level decreased with increasing salt stress and the highest SOD activity was measured in the control group 140Ru vines. CAT activity reached the highest level in 1103P at high salt stress. CAT and APX activities increased to higher levels with the second salt treatment than the first. The decrease in SOD enzyme more effectively manifested the use of biostimulants against stress, while CAT and APX activities showed an upward trend with the use of biostimulants, while CAT and APX activities showed an upward trend with the use of biostimulants.
