Keywords:allelochemicals, Chinese cabbage (Brassica pekinensis L.), lettuce (Lactuca sativa L.), Praxelis clematidea, soil incorporation
Praxelis (Praxelis clematidea (Griseb.) is an invasive weed in many crops. Praxelis extract has been shown to exhibit allelopathic activity inhibiting seed germination and growth of other weed species. This research aimed to investigate phytochemicals of praxelis, evaluate the allelopathic potential of crude extract, and determine allelopathic longevity in praxelis amended soil. Praxelis was extracted with methanol, 50% (v/v) aqueous solution. A series of dilutions of the crude extract were carried out and used in the determination of the phytochemicals. Chinese cabbage (Brassica pekinensis L.) and lettuce (Lactuca sativa L.) were used as test species in the bioassay of allelopathic studies and allelopathic longevity in praxelis amended soil, respectively. The results showed that praxelis extracts at higher concentrations had greater levels of phytochemicals including phenolics, flavonoids, and antioxidant activity. In a bioassay study, the praxelis extracts at 100% completely inhibited growth and germination of Chinese cabbage. The concentrations of 25% and 50% slightly inhibited Chinese cabbage germination but suppressed root and shoot growth. Praxelis amended soil reduced lettuce growth compared to untreated control, except 14 days after incubation. Based on toxicity evaluation, the praxelis allelochemicals in soil could last up to 7 days. The praxelis extracts exhibited the suppression of germination and growth of tested species. The results suggest praxelis extracts or praxelis amended soil contained potent allelochemicals which can lead to future use as a weed control option.
