title: [Research on allelopathic effects of phellamurine].
abstract: Conducted research on new allelochemicals phellamurine extracted from deciduous of Phellodendron amurense, which worked in allelopathy effect to seed germination and growth process of P. amurense and P. chinense in order to interpret the causes of rare seedlings of wild populations of P. amurense. Extracted and separated phellamurine from P. amurense deciduous, and treated the seeds of P. amurense and P. chinense in after-ripening stage and germination stage with different concentrations of phellamurine solution, then detection of the seed germination rate, germination index, seedling height, root length and seed vigor index to evaluate the allelopathic effect of phellamurine. The results show that: phellamurine solution at 0.30 g x L(-1) produce significant inhibition to seed after-ripening of P. amurense, and also the solution at 0.15 g x L(-1) produce significant inhibition to seeds germination of P. amurense; the solution at 0.15 g x L(-1) produce significant inhibition to seeds after-ripening and seeds germination of P. chinense, inhibition intensity increased with the concentration and enhanced. For both species, the presence of phellamurine can lower the seed germination rate, extend the germination time, reduce the ability of seedlings to adapt to the environment, thus the phellamurine may be one of the causes of rare seedlings in the wild population of P. amurense.
