Abstract The effects of Kocuria E43, Alcaligenes 637Ca and Pseudomonas 53/6 on combined lime and salinity stress in the soil were evaluated on strawberry cv. ‘Sweet Ann’. The results of the experiment showed that yield, average number and weight of fruit, leaf area, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) and sodium (Na) content of leaves, SPAD, stomatal conductance, membrane stability, protein and proline contents, hydrogen peroxide (H2O2) and malondialdehyde (MDA) contents and catalase (CAT), superoxide dismutase (SOD) and ascorbate peroxidase (APX) activity were considerably affected by rhizobacterial inoculations in strawberry plants. There was a remarkable enhancement in fruit weight, number and yield, leaf area, macro elements contents of leaves, SPAD, stomatal conductance, protein and proline contents and CAT, SOD and APX activity. On the other hand, the sodium content of leaves, membrane permeability, H2O2 and MDA contents were considerably reduced by rhizobacterial treatment. The 637Ca had the highest yield per plant (120.4 g), while the lowest value was found in the control (89.9 g). Average increases in N, P and Ca contents in the leaf were obtained from rhizobacterial root inoculations of 16%, 35% and 32%, respectively. The lowest stomatal conductance was found in the control (67 mmol/m2s), while E43 + 53/6 had the highest (384 mmol/m2s). The highest CAT, SOD and APX activity were obtained from 637Ca + 53/6 (563 µmol min−1 mg−1 FW), E43 + 637Ca + 53/6 (399 µmol min−1 mg−1 FW) and E43 + 637Ca (31.91 µmol min−1 mg−1 FW), respectively. These results suggested that the 637Ca, E43 + 53/6 and E43 + 637Ca + 53/6 treatments may be effective in reducing the negative impacts of combined salinity and high calcareous in soil.

促进植物生长的根际细菌减轻了草莓植物土壤中盐分和石灰的有害综合影响

摘要 在草莓品种上评价了 Kocuria E43、产碱杆菌 637Ca 和假单胞菌 53/6 对土壤中石灰和盐分胁迫的影响。《亲爱的安》。试验结果表明，果实的产量、平均果数和重量、叶面积、氮（N）、磷（P）、钾（K）、钙（Ca）、镁（Mg）和钠（Na）含量叶、SPAD、气孔导度、膜稳定性、蛋白质和脯氨酸含量、过氧化氢 (H2O2) 和丙二醛 (MDA) 含量以及过氧化氢酶 (CAT)、超氧化物歧化酶 (SOD) 和抗坏血酸过氧化物酶 (APX) 活性受到根际细菌接种的显着影响在草莓植物中。单果重、数量和产量、叶面积、叶片宏量元素含量、SPAD、气孔导度、蛋白质和脯氨酸含量以及 CAT、SOD 和 APX 活性。另一方面，根际细菌处理显着降低了叶片的钠含量、膜渗透性、H2O2 和 MDA 含量。637Ca 的单株产量最高（120.4 g），而最低值出现在对照（89.9 g）中。从根际接种的根际细菌中分别获得 16%、35% 和 32% 的叶中 N、P 和 Ca 含量的平均增加。对照中的气孔导度最低 (67 mmol/m2s)，而 E43 + 53/6 的气孔导度最高 (384 mmol/m2s)。最高的 CAT、SOD 和 APX 活性来自 637Ca + 53/6 (563 µmol min−1 mg−1 FW)、E43 + 637Ca + 53/6 (399 µmol min−1 mg−1 FW) 和 E43 + 637Ca (31.91 µmol min−1 mg−1 FW)，分别。这些结果表明 637Ca、
