개잎갈나무(Cedrus deodara)의 Allelopathy 效果
房基燮,吉奉燮 圓光大學校 基礎自然科學硏究所 1986 基礎科學硏究誌 Vol.5 No.1
Aqueous extracts of Cedrus deodara inhibited seed germination of Pennisetum alopecuroides, Aster agteratoides, Cassia tora and Oenothera odorata. The degree of inhibition on the germination became severe with increasing concentration. And tests using treatment with aqueous extracts in different developmental stages of each species demonstrated that the inhibition of growth was in the order : seed> 1 leaf stage> 3 leaves stage> 5 leaves stage, but the effect was decreased slightly from 5 leaves stage. To detect the inhibitor, allelochemicals, TLS and HPLC habe employed and 5 phytotocix substance were identified from the leaves of C. deodara. It is assumed that p-Hydroxybenzoic acid may be attributed to the main allelopathic effects of C. deodara on the tested species in this study.
