摘要:
为探究荧光假单胞菌的作用机制，本文通过盆栽外源根际接种试验，利用便携式CIRAS-Ⅱ型光合测定系统测定4株荧光假单胞菌菌株接种对东北山樱幼苗叶片净光合速率、蒸腾速率、气孔导度、胞间二氧化碳浓度、饱和水汽压差以及生长指标的影响。结果表明：与对照相比，3-7-2处理能够显著提高净光合速率、蒸腾速率和气孔导度，分别提高19.1%、40.0%和48.3%，茎粗净生长量极显著高于对照121.7%，株高净生长量也显著高于对照。3-8-2处理较对照显著提高净光合速率、蒸腾速率、气孔导度和饱和水汽压差，分别提高20.3%、40.0%、47.6%和4.7%，株高净生长量、茎粗净生长量、叶宽、叶片长度均极显著高于对照。由此可知，3-7-2和3-8-2两菌株促生效果较为显著。
