| 摘 要： | 研究火力楠根超临界提取物对马尾松种子的化感效应结果表明,纯CO2萃取的火力楠根生化物质对马尾松种子绝对发芽率、绝对发芽势、胚根长、胚轴长、鲜物质量及干物质量有显著抑制作用;夹带剂与CO2混合萃取的火力楠根生化物质对马尾松种子绝对发芽率、胚轴长及鲜物质量、干物质量有不同程度促进作用,而对绝对发芽势、胚根长则有抑制作用。

| Abstract: | The effect of extraction of Michelia macclurei root extracted by supercritical fluid on the seed germination of Pinus massoniana was studied. The results show that the alleochemicals of Michelia macclurei root extracted by pure CO_2 have significantly inhibitory effects on the absolute germination rate, absolute germination power, plumular root length, plumular axis length, fresh weight and dry weight. On the contrary, the alleochemicals of Michelia macclurei root extracted by entrainer mixed with CO_2 have positive effects on the absolute germination rate, plumular axis length, fresh weight and dry weight, but have inhibitory effects on the absolute germination power and plumular root length. |
