| 用五室方法研究了不同收获期三叶草根间菌丝桥对受体植株生长及体内磷营养状况的影响。结果表明三叶草根问菌丝矫形成以后，受体三叶草的生物量和体内磷的含量和浓度均有所增加，且与对照处理间的差异随接种时间的延长表现的更为明显。 |

| Effect of VA Mycorrhizal Hyphae Links on Growth and P Nutrient of Red Clover |
|
|
|
| Abstract: |
| ?Five compartments with a air gap was designed to examine underground phospho-rus transfer via VAM hyphae links between roots of red clover and its effects on the growthof receiver red clover. The experiment had two treatments: mycorrhiza and non-mycorrhizatreatments and each with nine replicates. Plants were harvested at 6 weeks, 8 weeks and 10weeks after planting. The results demonstrated that once VA mycorrhizal hyphae linksformed between plant roots, both plant growth and P nutrient status of receiver red cloverwere better than that of the control and the difference between treatments became more sig-nificant with time prolonged. |
