“…The use of moderately saline irrigation water and varying the way it is applied to the soil do affect the partitioning of ions throughout a grapevine. The high leaf Cl − concentration found in the deficit treatments shows a different level of hierarchy to that of previous work (Fisarakis et al , Tregeagle et al , Mohammadkhani et al ). Fisarakis et al () demonstrated that the roots of own‐rooted Thompson seedless grapes had the highest Cl − concentration, followed by the petioles and then laminae.…”

“…Tregeagle et al () also showed higher Cl − concentration in roots than in petiole and lamina of rooted leaves of two rootstock cultivars, while Mohammadkhani et al () reported that the shoots of various grapevine genotypes had the highest Cl − concentration followed by roots and then lamina regardless of salt concentration. The control treatment of our experiment showed the distribution observed by Fisarakis et al () and Tregeagle et al () (Tables , ) and may have been due to the ‘dilution effect’ on Cl − concentration with the leaf area being much larger than that of the two deficit treatments (Figure ). Munns () suggested that rapid expansion of growing cells, encouraging a high shoot‐to‐root ratio, would help to stop salts from building up to high concentration within the leaves.…”

Background and Aims: Deficit irrigation techniques have been used to improve water use efficiency and control vigour in grapevines, but the consequences of using saline water with these techniques have been little investigated. Here, we investigate the effect of deficit irrigation with moderately saline water on within-vine ion allocation. Methods and Results: Drip-irrigated own-rooted Shiraz and Grenache vines grown in pots were subjected to control, reduced control and partial root-zone drying (both approximately 50% less than control) irrigation treatments utilising moderately saline irrigation (mean of 2.46 dS/m) over two seasons. Plant water status and stomatal conductance were measured during the growing seasons, and at the end of the second season, the vines were destructively sampled to determine plant growth and concentration of ions of various vine structures. When compared against the control, partial root-zone drying had a higher total concentration of Cl À , Na + , K + and Ca ++ present on a whole vine basis. Although Cl À concentration was elevated in leaves for the partial root-zone drying treatment, it was partitioned away from leaves on a total content basis relative to both control and reduced control treatments. The partial root-zone drying treatment also resulted in significantly lower midday leaf water potential. Conclusion: Ion partitioning within grapevines depends on the type of deficit applied. Significance of the Study: Utilising deficit irrigation techniques in combination with saline irrigation water will alter the allocation of ions within a grapevine highlighting the importance of monitoring during the growing season for both fruit composition and long-term vine health.

“…In the present study, high petiole concentrations of Cl and Na were exacerbated by higher rates of N application in the vineyard. This result was unexpected, as it has been well documented that high Cl concentrations can inhibit NO 3 uptake in plants, 9,10 but if enough N is added then a deficiency can be overcome and tissue Cl will be reduced. 34 Therefore it was expected that N 100 and N 200 vines might display lower petiole Cl concentrations than J Sci Food Agric 2013; 93: 2393-2401 c 2013 Society of Chemical Industry control vines.…”

“…Some studies have considered varying salt concentration and how this might relate to some aspects of nitrogen nutrition. Examples include the impact of salt on vine nitrogen status 8,9 and salt effects when exposed to different forms of nitrogen (NO 3 or NH 4 ) in various crop plants. 10 The progressive salinisation of land, linked to climate change, is an increasing problem worldwide for agricultural production systems.…”

Vegetative growth, superoxide dismutase activity and ion concentration of salt-stressed watermelon as influenced by rootstock

SUMMARYWatermelon is a crop with a high water demand and is frequently grown under conditions of higher than normal root-zone salinity. In the present study, seedlings of watermelon (cv. Fantasy, Citrullus lanatus (Thunb.) Matsum & Nakai) were grown either ungrafted or grafted on three rootstocks: Strong Tosa, S1 (both Cucurbita maxima×Cucurbita moschata), or Emphasis (Lagenaria siceraria). All the plants were exposed to an NaCl-induced salinity stress (electrical conductivity, EC=2·2, 4·0, or 6·0 dS/m). The vegetative growth of all the plants substantially reduced after 2 weeks of exposure to 6·0 dS/m; however, growth of the plants grafted on Strong Tosa reduced less than that of the others. The leaf water content and specific leaf area (SLA, m2/g) decreased with an increasing salinity in grafted plants, but not in ungrafted plants. Salinity induced an increase of superoxide dismutase (SOD) activity in grafted plants up to two-fold depending on the rootstock, whereas it had no effect on this enzyme activity in ungrafted plants. Leaf Na+ concentration increased with increasing salinity in ungrafted and S1 grafted plants, whereas there was no significant leaf Na+ accumulation in Emphasis and Strong Tosa grafted plants. Leaf K+ concentration was affected by the rootstock but not by salinity, thus, the ability to keep a high K+/Na+ ratio was achieved mainly by limiting leaf Na+ concentration. The rootstock determined the leaf Cl− accumulation, with lower overall concentrations found if plants were grafted on the S1 rootstock than on Emphasis or ungrafted plants. Salinity significantly decreased the leaf NO3− concentration on Emphasis grafted plants only, while the NO3−/Cl− ratio was reduced in all the rootstocks. The capacity of Strong Tosa to withstand salt stress better than other tested rootstocks was probably due to the ability to induce anatomical adaptation (SLA) and SOD activity in response to salt stress, and also to the efficiency of Na+ exclusion from the shoot.
