Decreasing availability of non-saline water in arid and semiarid regions is one of prime concerns to all irrigated grape producers as the grapevine genotypes are not salt tolerant plants and producers often face the choice of either limiting fresh water application or using alternative saline waters. Present investigations were performed to analyze the effects of NaCl supplementation to irrigation water on the physiology and vegetative development of three grapevine rootstocks (41 B, 99 R and 140 Ru) commonly used across the world. Rooted cuttings of each rootstock were transplanted in pots and after the good establishment, salinity applications (0, 35 and 70 mM) were performed three times. EC and pH values of the growth substrate (perlite, peat and soil moisture) increased after the applications from 2.85 to 4.06 dS m⁻¹ and from 7.54 to 7.81, respectively. NaCl applications in 35 mM did not significantly impair most of the analyzed plant parameters, while the use of 70 mM concentration resulted in decrease of leaf temperature across the rootstocks used. Besides chlorophyll concentration and shoot growth of 41 B were significantly restricted by NaCl at 70 mM. NaCl in both doses also markedly reduced the shoot elongation course of 99 R. Overall findings revealed that 41 B was the most severely affected genotype among them, while 140 Ru performed better physiology and development under the effect of salination applications.

干旱和半干旱地区非盐水供应的减少是所有灌溉葡萄生产者的主要关注点之一，因为葡萄基因型不是耐盐植物，生产者经常面临限制淡水应用或使用替代盐水的选择。本研究旨在分析向灌溉水中补充 NaCl 对世界各地常用的三种葡萄树砧木（41 B、99 R 和 140 Ru）生理和营养发育的影响。将每根砧木的生根插条移植到盆中，建立良好后，进行 3 次盐度应用（0、35 和 70 mM）。施用后生长基质（珍珠岩、泥炭和土壤水分）的 EC 和 pH 值从 2.85 增加到 4.06 dS m ^-1和分别从 7.54 到 7.81。使用 35 mM NaCl 不会显着损害大多数分析的植物参数，而使用 70 mM 浓度会导致所用砧木的叶片温度降低。此外，41 B 的叶绿素浓度和枝条生长受到 70 mM NaCl 的显着限制。两种剂量的 NaCl 也显着降低了 99 R 的枝条伸长过程。总体研究结果表明，41 B 是其中受影响最严重的基因型，而 140 Ru 在盐化应用的影响下表现出更好的生理和发育。
