蚕豆根缘细胞对加拿大蓬挥发油的响应
Response of Root Border Cells of Vicia faba L.to Volatile Oil from Erigeron canadensis L.
摘要
Abstract
Allelopathy is one of the mechanisms by which an invasive alien species, Erigeron canadensis L.(horseweed) invades successfully and spreads rapidly.In order to further explore allelopathic and invasion mechanisms of this species, allelopathic effects ofvolatile oil from this species on root border cells and the activity of pectin methylesterase(PME) of broad bean were studied by aeroponic culture.The results showed that the volatile oil from E.canadensis inhibited the root growth, and the survival rate of root border cells decreased, and the activity of root pectin methylesterase increased.But the stimulating effect gradually lowered down along with the increasing doses of the volatile oil and treatment times.These results suggested that volatile oil from this species caused root border cells death and inhibited the growth of ambient plants.关键词
