摘要/Abstract

摘要： 应用5室分隔法研究了供体三叶草体内的³²P通过菌丝桥向受体黑麦草的传递作用。结果表明,菌根侵染供体三叶草根系之后,根外菌丝可穿过中室到达受体植株根室而再度侵染受体黑麦草的根系,从而形成三叶草-黑麦草根系之间的菌丝桥;供体三叶草体内的³²P可通过根间菌丝桥传递给受体黑麦草,³²P的传递量随受体植株施磷水平的提高而降低.

关键词: 菌丝桥, 三叶草, 黑麦草, 养分传递

Abstract: Afive compartments system was used to examine ³²P transfer via vesicular arbuscular mycorrhizal hyphal links from red clover to rye grass. The results show that after mycorrhizal fungus were inoculated in the root compartment for donor plant, hypha out of the donor's roots penetrated the central compartment, and reached the root compartment for receiver plant and inoculated its roots. Therefore, hyphal links were formed between roots of donor red clover and receiver rye grass, and could transfer ³²P from red colver to rye grass. The amount of ³²P transfer was decreased as Psupplied to the receiver plant increased.

Key words: Hyphal links, Red clover, Rye grass, Nutrient transfer
