A pot experiment was designed to study the effect of Azotobacter and Azospirillum inoculation on the growth parameters (root shoot fresh weight, dry weight and length), level of enzymatic and non-enzymatic antioxidants, photosynthetic pigments, water status, level of osmolytes and metaxylem vessel elements (MVE) of maize roots under control conditions as well as under salt stress conditions (100 mM and 150 mM NaCl). The results revealed that stress conditions increased the level of antioxidants, antioxidant enzyme activities and some osmolytes like total soluble sugars and proline. On the contrary, growth parameters, total soluble proteins, photosynthetic pigments and MVE number and area were reduced under salt stress. Inoculation with Azotobacter and Azospirillum improved the growth parameters, increased the level of osmolytes, antioxidants, activities of antioxidant enzymes, photosynthetic pigments and MVE area and number, not only under control conditions but also under stress conditions. It was observed that bacteria inoculation counter acted on the harmful effects of salt stress. Therefore to conclude, inoculation of seeds with microbes before sowing in salt affected soils can mitigate the negative effects of salt stress.

设计了一个盆栽试验来研究固氮菌和固氮螺菌接种对生长参数（根茎鲜重、干重和长度）、酶促和非酶促抗氧化剂水平、光合色素、水分状况、渗透质和间质木质素水平的影响。在对照条件下以及在盐胁迫条件下（100 mM 和 150 mM NaCl）下玉米根的血管成分（MVE）。结果表明，压力条件增加了抗氧化剂、抗氧化酶活性和一些渗透物（如总可溶性糖和脯氨酸）的水平。相反，盐胁迫下生长参数、总可溶性蛋白、光合色素和MVE数量和面积减少。接种固氮菌和Azospirillum不仅在控制条件下而且在胁迫条件下都改善了生长参数，增加了渗透物、抗氧化剂、抗氧化酶活性、光合色素和 MVE 面积和数量的水平。据观察，细菌接种计数器作用于盐胁迫的有害影响。因此，总而言之，在受盐分影响的土壤中播种前用微生物接种种子可以减轻盐胁迫的负面影响。
