水杉生化他感作用生物测定的结果表明：水杉通过淋洗、根系分泌物和挥发作用等途径释放他感物质，对小麦种子的萌发和小麦、青菜幼根、幼苗的生长产生不同的影响。他感物质浓度高时显著抑制植物的生长发育，随着浓度的降低，这种抑制作用会逐渐减弱、消失甚至转变为促进作用。不同的受体植物对他感物质的反应也有差异。在供试的受体植物中，小麦种子萌发及幼苗、幼根生长受他感物质的影响小于青菜，这一结论可作为复合农林业系统植物配置的参考。 Metasequoia glycosides biochemical sense of the results of his bioassay showed that: Metasequoia through rinse, root exudates and volatiles and other means to release his sense of substance, the wheat seed germination and wheat, young root vegetables, seedlings growth have different effects. He felt that when the substance concentration was high, the growth and development of plants were significantly inhibited. With the decrease of the concentration, the inhibition would gradually diminish, disappear or even change into a promoting effect. The response of different recipient plants to his sensory substances is also different. In the tested recipient plants, the germination of wheat seedling and the growth of young seedling and young root were less influenced by the sensory substances than that of Chinese cabbage. This conclusion can be used as a reference for plant configuration of the agroforestry system.
