“…The findings were in agreement with the who reported that Lantanacamera release certain secondary metabolites as phenolic acids (Narwal, 1994) or/and phytotoxic chemicals, called as allelochemicals. Such allelochemicals hampers the seed germination and seedling growth due to the suppression of cellular membrane developments and increase in the production of reactive oxygen forms (Gindri et al, 2020). According to Kong et al, (2006) Lantadene A and lantadene B were isolated from aqueous extracts of Lantana camara leaves as allelochemicals.…”

Allelopathy is a biotic interaction between plants where one plant inhibits the germination and growth of other plants by releasing certain allelochemicals. In this research we evaluated the allelopathic effect of aqueous leaf extract of Lantana camara on the germination and growth of four crop plants. The experiment was conducted in sterilized petri dishes in Botany lab of Saptagandaki Multiple Campus, Bharatpur, Chitwan, Nepal. The effect of different concentrations of extracts was studied and compared with the control. The results revealed that the germination and seedling growth of all species were significantly inhibited at different concentrations as compared to the control. The lowest germination percentage and seedling growth was found in Brassica campestris and Oryza sativa plant respectively and effect was least in Triticum aestivum plant at 10% concentration. The germination percentages, seedling growth and, biomass in all species were observed to reduce, with the increasing concentration of aqueous extracts. The study concluded that Lantana camara leaf extract allelochemicals have adverse effects on germination, seedling growth and dry matter accumulation of all tested crops.

“…Hatata and El-Darier [ 37 ] found that the activity of APX was higher in wheat leaves when treated with Achillea santolina shoot extract. Gindri et al [ 38 ] also stated that Lantana camara L. increased the APX activity of the host plant ( Avena sativa L.) seedling. According to Ding et al [ 39 ], higher SOD activity was measured in garlic ( Allium sativum L.) root exudates treated with lettuce extract, which contradicts with our results.…”

Woolly cupgrass (Eriochloa villosa (Thunb.) Kunth) is a new invasive weed in Hungary. This study was conducted to elucidate the effects of this weed on the biochemistry and growth of maize (Zea mays L. cv. Armagnac) under greenhouse conditions. Activities of the antioxidative enzymes (ascorbate peroxidase (APX), guaiacol peroxidase (POD), superoxide dismutase (SOD)), the contents of malondialdehyde (MDA), and protein were measured in the shoots and roots, whereas the content of the photosynthetic pigments was measured only in the shoots. The measured growth parameters included plant height, root length, root volume, root and shoot dry weight, and stem diameter. Results showed the allelopathic effects of woolly cupgrass on maize, with significant decreases in plant height, root length, root volume, and root dry weight. Woolly cupgrass infestation (WCI) induced significantly higher activities of APX and SOD in the shoots, whereas POD was only induced in the roots. The contents of chlorophyll-a, total chlorophyll (including relative chlorophyll), carotenoids, and root protein were substantially reduced by WCI, except for the leaf chlorophyll-b. The results suggest that high APX and SOD activities in the shoots could be involved in stabilizing the leaf chlorophyll-b, chlorophyll a/b, shoot protein, and shoot dry weight because all of these parameters were not inhibited when these two enzymes were induced. In contrast, high activity of POD in the roots is not effective in counteracting allelopathy. Therefore, it would be worthwhile to further investigate if an increase in the activities of APX and SOD in the shoots of WCI maize is responsible for stabilizing leaf chlorophyll-b, shoot protein, and shoot dry weight, which could contribute to improved maize yield under WCI.

“…Aqueous leaf extracts of L. camara inhibited the germination of Lactuca sativa L. due to the suppression of cellular membrane developments and increase in the production of reactive oxygen forms [32]. Aqueous leaf extracts of L. camara suppressed the development of leaf buds of Eichhornia crassipes Mart., increased the decay, and caused necrosis of E. crassipes leaves.…”

Allelopathy of Lantana camara as an Invasive Plant

Lantana camara L. (Verbenaceae) is native to tropical America and has been introduced into many other countries as an ornamental and hedge plant. The species has been spreading quickly and has naturalized in more than 60 countries as an invasive noxious weed. It is considered to be one of the world’s 100 worst alien species. L. camara often forms dense monospecies stands through the interruption of the regeneration process of indigenous plant species. Allelopathy of L. camara has been reported to play a crucial role in its invasiveness. The extracts, essential oil, leachates, residues, and rhizosphere soil of L. camara suppressed the germination and growth of other plant species. Several allelochemicals, such as phenolic compounds, sesquiterpenes, triterpenes, and a flavonoid, were identified in the extracts, essential oil, residues, and rhizosphere soil of L. camara. The evidence also suggests that some of those allelochemicals in L. camara are probably released into the rhizosphere soil under the canopy and neighboring environments during the decomposition process of the residues and as leachates and volatile compounds from living plant parts of L. camara. The released allelochemicals may suppress the regeneration process of indigenous plant species by decreasing their germination and seedling growth and increasing their mortality. Therefore, the allelopathic property of L. camara may support its invasive potential and formation of dense monospecies stands.
