Effects of Decursin and Decursinol on the Germination and Growth of Plants

Decursin과 Decursinol이 식물의 생장과 발아에 미치는 영향

Biological activities of decursin and decursinol, natural coumarin derivatives, on the germination, growth and adventitious root formation of several plants were observed. In 10 ppm 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 100 ppm of each chemcials, 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.
