人工栽培雷公藤水浸提液对杉木种子发芽的化感效应

Allelopathy Effect of Aqueous Extracts from Artificial Planted Tripterygium wilfordii Hook. F on Cunninghamia lanceolata Seed Germination

利用水浸提的方式对人工栽培雷公藤的生化物质进行提取,通过杉木种子发芽实验进行生物检测.分析结果表明：人工栽培雷公藤的水浸提物在高浓度下能够抑制杉木种子的萌发和生长,但是在中、低浓度下对杉木种子的萌发和生长有显著的促进作用,这有可能为雷公藤与杉木合理混交密度的研究提供可靠的实验依据.

Cunninghamia lanceolata seedlings were treated with different concentrations aqueous extracts from different organs of artificial planted Tripterygium wilfordii Hook.F.The results show that the aqueous extracts of the different parts of artificial planted Tripterygium wilfordii Hook.F have a negative effect on high concentration but positive effect on low concentration.The results could offer the gist for mixed forest research.
