河川の樹林化に対するマイコライザの影響の評価と河川樹林化モデルへの導入

我从河岸上收集土壤。以多年生黑麦草（Loliumperenne）种子为材料，在河岸土壤中接种菌根菌和不接种菌根菌，研究了菌根菌对多年生黑麦草种子生长的影响。将不同剂量的砷（As）（0 ppm、5 ppm、10 ppm和20 ppm）添加到土壤中。AM真菌接种效果受土壤砷含量的影响，随土壤砷含量的增加而降低。砷剂量对植物的生长也有影响，尤其是根系的生长。根生长严重减少与20 ppm的砷，植物达到衰老早于对照植物。与不接种AMF的植物相比，接种AMF后植物的叶绿素、活性氧和抗氧化酶的含量减少。

I have collected soil from river banks. Seed of perennial ryegrass (Lolium perenne), which is a very common plant in riverbank habitat, were grown in the riverbank soil with and without mycorrhizal inoculants. Different doses of arsenic (As) (0 ppm, 5 ppm, 10 ppm, and 20 ppm) were added to the soil. AMF inoculation effectiveness was affected by the levels of arsenic, and it decreased with increasing arsenic concentration is soil. Arsenic dose also affected the growth of plant, especially root growth. Root growth was severely reduced with 20 ppm arsenic, and the plants reached senesce earlier than the control plants. Plants were less stressed (in terms of chlorophyll, ROS, antioxidative enzymes production) when grown with AMF in compared to those without AMF inoculation.
