Abstract
|
|
|
|
Biological activities of decursin and decursinol, natural coumarin derivatives, on the germination, growth and adventitious root formation of several plants were observed. In 10ppm of decursin or decursinol, the growth of Avena coleoptile sections was inhibited, and the activity of IAA-oxidase was gradually enhanced by the increase of its concentrations. Inhibition effect on seed germination was observed from 100ppm of each chemicals, and the activity of amylase in the germinating seeds was also gradually decreased. However, In the higher concentrations of decursin, the inhibited germination rate of wheat was slightly reduced. Decursin and decursinol also promoted the adventitious root formation in seeds of Phaseolus vulgaris.
