杨梅或杨梅，莫雷拉，(MC)为杨梅科成员，与中国杨梅（莫雷拉红）（MR）同属。它是一种常绿灌木，原产于美国宾夕法尼亚州，耐盐碱胁迫。我国东南沿海地区盐碱地面积大，本研究旨在评价MR品种‘碧奇’嫁接MC在盐碱地上的适宜性。该MC砧木耐受高钠、镁和钙浓度的土壤胁迫，没有毒性症状。"碧奇"在盐碱地上生长正常，叶片呈深绿色，叶绿素含量高，外观健康;而在盐碱地上，嫁接在MR上的植株黄化严重。在2016 - 2018年期间，在盐碱土壤中嫁接在MC上的“Biqi”品种的平均果实重量稳步增加，并且比沿海或山区种植的MR砧木的果实更大，蔗糖和柠檬酸含量更高。嫁接在MC砧上的杨梅也比嫁接在MR砧上的杨梅提早1-2年开花坐果。在嫁接界面的显微切片中观察到接穗（MR）和砧木（MC）之间的高度相容性。因此，杨梅是盐碱地杨梅栽培的有效砧木。
Wax bayberry or wax myrtle,Morella ceriferaL., (MC) is a member of the Myricaceae family and belongs to the same genus as Chinese red bayberry (Morella rubra) (MR). It is an evergreen shrub native to Pennsylvania, USA, and is resistant to saline-alkali stress. China has a large area of saline-alkali soil in the south-eastern coastal regions, and this study aimed to evaluate the suitability of MR cv ‘Biqi’ grafting on MC for cultivation on saline soil. This MC rootstock tolerated stress in soil with high sodium, magnesium and calcium concentrations with no toxicity symptoms. Trees of cv ‘Biqi’ grafted on MC grew normally in saline-alkali soil, with dark green leaves, high chlorophyll content and healthy appearance, while the trees grafted on MR suffered severe chlorosis in saline alkali soil. The average fruit weight of the ‘Biqi’ cultivar grafted on MC in saline alkali soil steadily increased over the 2016–2018 period, and were larger in size and higher in sucrose and citric acid content than those on the MR rootstock grown in either coastal or mountainous areas. The bayberry grafted on MC rootstock also tended to flower and set fruit 1–2 years earlier than that grafted on MR rootstock. High compatibility between the scion (MR) and rootstock (MC) was observed in the microscopic section of the grafting interface. Thus, wax bayberry was considered an effective rootstock for the cultivation of red bayberry in saline-alkali soils.
