Two pot experiments were directed under open field conditions where green bean (Phaseolus vulgaris L.) plants cv. Valentino were irrigated with four levels of salinity (1000, 2000, 3000 and 4000 ppm) combined with two anti-salinity agents (Arbuscular Mycorrhizal fungi [AMF] Glomus irradicans 10% w/w, Bacillus megaterium [10 ml/pot] and non-inoculated plants as control) to counteract the negative effect of salt stress, improve the growth, yield, enzymes activity and chemical composition of green bean plants during 2017and 2018 growing seasons. All salinity amelioration treatments (AMF and Bacillus megaterium) significantly improved vegetative growth, shoots biomass (total fresh and dry weight per plant), chlorophyll and antioxidant enzymatic activity at all verified salinity levels compared with non-inoculated plants (control) which showed severe growth retardation especially under the higher salt concentration (4000 ppm). The lowest values of membrane permeability and maximum leaf relative water content were significantly obtained with AMF and B. megaterium. Plants irrigated with lower concentrated saline water (1000 ppm) significantly accumulated lower Na and Cl and higher K than plants irrigated with higher concentrated salinity irrigation water (4000 ppm). The anti-salinity application increased green bean pod yield under all salinity stress levels particularly with AMF followed by B. megaterium compared with non-inoculated plants.

AMF和巨大芽孢杆菌中和盐胁迫对豆类植物的有害影响

在田间条件下进行了两个盆栽实验，在该条件下，绿豆（菜豆 ）被种植。瓦伦蒂诺用四种盐度水平（1000、2000、3000和4000 ppm）与两种抗盐剂（丛枝菌根真菌[AMF] Glomus irradicans 10％w / w，巨大芽孢杆菌[10 ml /罐] ）结合灌溉-接种的植物作为对照），以抵消盐胁迫的负面影响，改善2017年和2018年生长期的绿豆植物生长，产量，酶活性和化学成分。所有盐度改善治疗（AMF和巨大芽孢杆菌）与未接种植物（对照）相比，在所有已验证的盐度水平下，营养生长均得到显着改善，芽生物量（每株植物的新鲜和干重总计），叶绿素和抗氧化酶活性（尤其是在较高盐浓度下（4000）显示出严重的生长迟缓） ppm）。AMF和巨大芽孢杆菌的最低膜渗透率和最大叶片相对含水量。与用高浓度盐分灌溉水（4000 ppm）灌溉的植物相比，用较低浓度的盐水（1000 ppm）灌溉的植物积累的Na和Cl和钾含量明显较高。在所有盐分胁迫水平下，抗盐分施用均可提高绿豆荚的产量，尤其是AMF其次是巨大芽孢杆菌 与未接种的植物相比。
