Allelopathic effects of Amaranthus spinosus L.
Abstract
In order to investigate the competitive dominant, herbicide and antifungal of Amaranthus spinosus L., this study was investigated germination characteristics as effects of several temperature conditions on germination of A. spinosus L. and allelopathic effects of A. spinosus L..
The germination of A. spinosus L. increased with the rise in temperature. Especially, it was the highest at 35~40℃ treatment but decreased at 45℃ treatment. It was generally decreased the Relative Germination Ratio(RGR), the Relative Elongation Ratio(RER), the Relative Fresh weight Ratio(RFR) of receptor plants by the aqueous extracts of concentration of A. spinosus L. but differented to growing regions and the kind of receptor plants. The antifungal activity was shown by increased the aqueous extracts of concentration of A. spinosus L. in Phytophthora infestanse, Pythium vanterpolii, Diaporthe citri. and Sclerotinia sclerotiorum, Botrytis cinerea Rhizoctonia solani AG-1(1A), Rhizoctonia solani AG-2-2(iiiB), and Rhizoctonia cerealis. On the other hand, it was unrelated the growth of Glomerella cingulata, Pythium ultimum with aqueous extracts of A. spinosus L. So it showed different effects according to species of plants and microbes. The total phenolic compounds content of A. spinosus L. was decreased gradually middle, first, and last of growth stage and was decreased gradually to leaves, roots, and stems.
Therefore, I think that A. spinosus L. hold a dominant position by germination characteristics and allelopathic effects in ecosystem of Jeju Island.
