In this study, pepper (Capsicum annuum L.) inbred lines were grafted onto different rootstock genotypes and tested under saline conditions. A hydroponic experiment was conducted in nutrient solution growth system in a growth chamber of Erciyes University, Agricultural Faculty in Kayseri, Turkey. The experiment was conducted in spring 2017 growth season. Two pepper inbred lines (ERÜ-462 and ERÜ-1227) were grafted onto three different pepper rootstocks/genotypes (Scarface F1, 11B14, and Yaocali F1) and grown in 8 L pots filled with continuously aerated nutrient solution under saline conditions (8 dS m⁻¹) with three replications. The growth chamber experiment was carried out to determine the effects of salt stress on plant growth, shoot and root dry weights, leaf area, photosynthesis, leaf total chlorophyll (a + b) and carotenoid content, proline content, glycine betaine content, leaf electrolyte leakage, leaf and root macro element concentration in grafted and non-grafted pepper plants. The results indicated that ERÜ-462 grafted on to Scarface and 11B14 rootstock genotypes were more tolerant to salinity than ERÜ-1227 in term of leaf chlorophyll (a + b) content and leaf carotenoid content, photosynthesis, and proline content. Though, higher shoot and root biomass, leaf area formation, root K⁺, Na⁺, Cl⁻ contents were observed when ERÜ-1227 grafted on to Scarface and 11B14 rootstock genotypes. Strong rootstock promoted plant growth in pepper plant both under control and saline conditions and significant depression of plant biomass production under saline conditions was observed in both grafted and non-grafted plants. However, grafting onto vigorous rootstocks alleviated negative effects of salinity stress on pepper plants. Scarface and 11B14 were found more tolerant to salinity than non-grafted pepper plants and the other genotypes used as regard to investigated parameters.

在这项研究中，辣椒 ( Capsicum annuum  L.) 自交系被嫁接到不同的砧木基因型上，并在盐水条件下进行测试。在土耳其开塞利农业学院 Erciyes 大学的生长室中，在营养液生长系统中进行了水培实验。试验在2017年春季生长季节进行。将两个辣椒自交系（ERÜ-462 和 ERÜ-1227）嫁接到三种不同的辣椒砧木/基因型（Scarface F1、11B14 和 Yaocali F1）上，并在盐水条件（8 dS米^-1）与三个副本。进行生长室试验以确定盐胁迫对植物生长、芽和根干重、叶面积、光合作用、叶片总叶绿素（a+b）和类胡萝卜素含量、脯氨酸含量、甘氨酸甜菜碱含量、叶片电解质的影响嫁接和非嫁接辣椒植株的渗漏、叶和根宏量元素浓度。结果表明，在叶片叶绿素（a + b）含量和叶片类胡萝卜素含量、光合作用和脯氨酸含量方面，接枝到 Scarface 和 11B14 砧木基因型的 ERÜ-462 比 ERÜ-1227 更耐盐。但是，较高的地上部和根系生物量、叶面积形成、根系 K ⁺、Na ⁺、Cl ^-当 ERÜ-1227 嫁接到 Scarface 和 11B14 砧木基因型时，观察到了含量。在对照和盐分条件下，强砧木促进了辣椒植物的植物生长，并且在嫁接和未嫁接植物中观察到盐分条件下植物生物量产生显着降低。然而，嫁接到健壮的砧木上减轻了盐分胁迫对辣椒植物的负面影响。发现 Scarface 和 11B14 比未嫁接的辣椒植物和其他基因型对盐度的耐受性更强。
