Arbuscular mycorrhizal symbiosis is the mutualistic association between AM fungi and most terrestrial plants: the plant roots offer carbohydrates to the fungi; in return, the fungi assist the plants with uptake of mineral nutrients, particularly phosphate, from soil, and their subsequent transfer to the root cortical cells.

南京农业大学资源与环境科学学院，南京 210095摘要丛枝菌根(arbuscular mycorrhizal， AM)共生是丛枝菌根真菌与大多数陆地植物的根系之间形成的一种互利共生关系。植物给菌根真菌提供碳水化合物；作为回报，菌根真菌能够增强植物对矿质营养元素的吸收。

This report presents 2 cases of inadvertent injection of sodium hypochlorite into the periradicular tissue because of apical constriction destruction and canal perforation.

This conclusion is based on three groups of experiments with detached root tips of wheat seedlings: By following the time course changes of NO synthase , superoxide synthase and ABA accumulation under dehydration stress, we found that ABA accumulation was preceeded by the changes of NOS and superoxide synthase. ABA accumulation induced by dehydtrion stress and osmotic stress can be blocked by NO scanvegers and NOS inhibitors, while only dehydration stress-induced ABA accumulation can be blocked by ROS scanvegers. Exogenous applied NO or ROS induced ABA accumulation in root tips of wheat seedlings, and synergistic effects were found between NO and NO. The in planta expereiments also proved that ROS and NO are involved in water stress-induced ABA accumulation.Ⅱ.

证据主要来自以离体根尖为材料的实验：(1)通过检测干旱胁迫下小麦根尖NOS活性、O〓合成酶活性和ABA积累的时间变化进程，发现ABA积累滞后于ROS和NO的变化；(2)抑制剂实验表明，NO清除剂和NOS抑制剂可以抑制自然干旱胁迫及渗透胁迫诱导的小麦根尖ABA积累，ROS清除剂抑制自然干旱胁迫诱导的ABA积累而不抑制渗透胁迫诱导的小麦根尖ABA积累；(3)在非胁迫条件下施加外源的ROS或NO可以诱导小麦根尖积累ABA，ROS和NO之间具有协同作用。

Var. pyramidalis is not positively correlated with ion concentration in growth environment, the capacity of selective absorption and transport of ions in Populus alba L. var. pyramidali under salt stress in drainage canal is higher than Populus alba L. var. pyramidal is of normal growth in irrigation canal. Under salt stress, the concentration of K(superscript +)、Na(superscript +) of roots and leave of Populus alba L. var. pyramidalis have changed, the concentration of K(superscript +) of roots and leave dropt the concentration of Na(superscript +) of roots markedly increased, the concentration of Ca(superscript 2+), Mg(superscript 2+) have slightly changed, the concentration of Ca(superscript 2+) of roots dropted, the concentration of Mg(superscript 2+) increased, the concentration of Ca(superscript 2+), Mg(superscript 2+) of leave increased.
