中文摘要中国红豆杉（Taxus chinensis var.）对喜树幼苗生长有显著的促进作用。从T.中国变种通过光谱分析鉴定了海葵根提取物及其结构。在T.中国变种根分泌物、根际土壤中，其浓度范围为0.01 ~ 5.90 μg/g。在T.中国变种四种化学物质均能显著促进金鱼藻的生长。acuminata幼苗因此，T.中国变种根分泌物可能作为化感物质促进青冈的生长。尖叶幼苗生长量与C.化感物质对尖叶百合幼苗生长、土壤性质、酶活性和微生物群落的影响。研究结果为深入了解C. acuminata和T.中国变种mairei互动
ABSTRACT The root extracts and root exudates from the Taxus chinensis var. mairei had significant promote effects on growth of Camptoteca acuminata seedlings. Four taxane chemicals, cephalomannine, 10-deacetylbacatin III, paclitaxel and 7-Epi-10-deacetyl-paclitaxel, were isolated from T. chinensis var. mairei root extracts and their structures were identified by spectroscopic analysis. The chemicals were detected in T. chinensis var. mairei root exudates, rhizosphere soils, and their concentrations ranged from 0.01 to 5.90 μg/g. At an approximate concentration determined in T. chinensis var. mairei root exudates, all four chemicals significantly promoted the growth of C. acuminata seedlings. Therefore, four chemicals from T. chinensis var. mairei root exudates may act as allelochemicals accelerating growth of C. acuminata seedling. There were significant relationships between growth of C. acuminata seedlings, soil properties, enzyme activities and microbial community under allelochemicals’ application. The results provide a reference for in-depth understanding of C. acuminata and T. chinensis var. mairei interactions.
