| 摘 要： | 对银杏实生苗接种VAM真菌,叶面喷施N、P肥及干旱胁迫处理,测定银杏生长及黄酮苷和萜类内酯含量的变化,试验结果表明:增施N、P肥能显著改善银杏植株N、P供应,增加银杏苗叶量和干重,显著提高银杏叶萜类内酯含量,而对银杏黄酮苷含量影响较小;干旱胁迫降低银杏叶水势和萜类内酯含量,对银杏黄酮苷含量没有影响,接种VAM真菌能减轻干旱胁迫的负影响,显著提高银杏萜类内酯含量。银杏萜类内酯的生物合成代谢与银杏生长状况密切相关 |
| 关 键 词： | N、P肥 VAM真菌 干旱胁迫 黄酮苷 萜类内酯 银杏生长 |

| Abstract: | Effects of VAM fungi(Glomus mosseae and G versiforme)、N、P fertilizer and drought stress on the growth as well as flavonol glycosides and terpene lactone content of Ginkgo biloba seedlings were measured,experimental results showed that VAM fungi、N、P fertilizer obviously increased uptake of N、P elements,improved growth,enhanced terpene lactone content,drought stress decreased leaf water potencial and terpene lactone content of ginkgo biloba seedlings,those negative effects might be compensated by infection of host plants with both VAM fungi in some extent.Biosynthesis and metabolize of terpene lactones of ginkgo bilobamight be close relative to growth status of Ginkgo biloba seedlings.VAM fung；,N、P fertilizer drought stress had little effect on flavonol glycoside content of Ginkgo biloba. |
| Keywords: | N、P fertilier VAM fungi drought stress flavonol glycosides terpene lactone Ginkgo biloba |
