Abstract

Laboratory and greenhouse experiments were conducted to determine the effects of aqueous extract and the debris of Mile-a-Minute (Mikania micrantha H.B.K.) on the germination and growth of four test species, viz. tomato (Lycopersicon esculentum Mill.), Chinese cabbage (Brassica chinensis L.), corn (Zea mays L.) and long bean (Vigna sesquipedalis L.). Germination percentage, radicle length and fresh weight of two crops, Chinese cabbage and tomato, decreased progressively when plants were exposed to increasing concentrauons (12.5, 25, 37.5 and 50gL-1) of aqueous extract of Mikania, but did not affect those of corn and long bean seedlings. The emergence of tomato and Chinese cabbage was greatly reduced when Mikania debris was incorporated into the soil, irrespective of the amount of debris and the decomposition period. In contrast, the emergence of corn and long bean seedlings was not affected. The application of fertilizer (NPK 15:15:15) enhanced the fresh weight of all seedlings tested as compared with those not supplied with the fertilizer. Four compounds were identified in the leaf extract of Mikania, viz. caffeic acid, p-hydroxybenzaldehyde, resorcinol and vanillic acid.
