比较三种水浸提液处理组根边缘细胞黏胶层厚度和凋亡率的关系可知，辣子草水

Comparing the relationship between the thickness of the root margin cell viscous layer and the apoptosis rate in the three water extracts treatment group, we can see that the thickening of the viscose layer in the hot spring grass water extract treatment group is the largest, and the root margin cell apoptosis rate is the smallest, on the contrary In the treatment group of the water extract of the schizonepeta, the change range was the smallest, and the apoptosis rate of the root edge cells was the largest. The water extract of the schizonepeta is highly toxic to the buckwheat root edge cells, which affects the intracellular mucus secretion system, resulting in the root edge cells secreting insufficient viscous layer to resist allelopathy in the water extract, resulting in cell withering Die.

Comparing the relationship between the thickness and apoptosis rate of the three water-soaked liquid treatment group root-edge cells, the relationship between the viscose layer thickening of the spicy grass-water-soaked liquid treatment group was the largest, the root edge apoptosis rate was the smallest, on the contrary, the change of the soil-hot mustard water-soaked liquid treatment group was the smallest, the root edge apoptosis rate was the largest, indicating that the spicy grass was more able to stimulate the secretion of the grass-roots wheat root edge cells to protect the damage of the muscous substance. The soil mustard water-soaked liquid is highly toxic to the edge cell of buckwheat root, affecting the cell mucus secretion system, resulting in the mucous layer secreted by the root edge cells is not sufficient to resist the chemical substance in the water-soaked liquid, which leads to apoptosis.

By comparing the relationship between the thickness of the mucilage layer and the apoptosis rate of the root border cells in the three kinds of water extract treatment groups, it can be seen that the mucilage layer thickens the most and the apoptosis rate of the root border cells is the least in the horseradish water extract treatment group, on the contrary, the change range of the water extract treatment group is the smallest and the apoptosis rate of the root border cells is the largest, which shows that horseradish can stimulate the secretion of a large number of tartary buckwheat root border cells Protect mucus to alleviate the damage of allelochemicals. The toxicity of the aqueous extract of Schizonepeta tenuifolia to the limbic cells of buckwheat roots was strong, which affected the secretion system of intracellular mucus, resulting in that the mucilage layer secreted by the limbic cells of buckwheat roots was not enough to resist the allelochemicals in the aqueous extract, thus leading to apoptosis.
