“…Several studies have shown that various allelopathic plants caused both suppression and stimulation of growth of the tested species (Hong et al, 2004;Batish et al, 2007;Hernández-Aro et al, 2016). However, the results obtained in this study are the first report on the allelopathic potential of M. pigra.…”

AbstractThe most of invasive alien species possess allelopathic properties for beneficial success in site establishment. Giant sensitive plant (Mimosa pigra L.) is an important invasive species in nature. The objective of this study was to evaluate the allelopathic activity of M. pigra leaf residues on the germination, survival percentage and growth in two weeds, namely popping pod (Ruellia tuberosa L.) and purslane (Portulaca oleracea L.). Experiments were carried out under laboratory (agar medium) and greenhouse (soil medium) conditions with the addition the M. pigra leaf powder at varying concentrations of 1, 2, 3 and 4% (w/w) into the agar and soil medium. Negative and positive effects of M. pigra leaf residues were assessed. The results under two conditions showed the same trend, namely that the M. pigra leaf samples expressed inhibitory effects on the germination, survival percentage and growth of popping pod and exhibited stimulatory effects on purslane for all parameters. The soil experiment showed more prominent effects than the laboratory bioassay, with the dry biomass of popping pod being decreased up to 70.27% whereas the dry biomass of purslane sharply increased up to 1,562.50% and the effects became stronger when the concentration of M. pigra increased. The results indicated that the allelopathic effects of M. pigra were species-specific and concentration-dependent. The M. pigra leaf residues could be considered as a source of biologically active compounds.

Objective: This paper mainly discusses the Allelopathic potential of wheat. Methods: This paper is prepared by reviewing the latest academic literatures. Result: The green revolution in the 1960s caused an increase in the demand for food. The agricultural sector and farmers tended to spend more time on the agricultural work but the crop yield was suppressed by the weeds. Hence, the usage of herbicide insecticides, fungicides and others chemicals had been increased. Although herbicides are efficient for weed controls, the continuous uses had gradually stimulated the weeds developing an effecttive resistance to the chemicals. Wheat (Triticum aestivum L.) is known as allelopathic against crops and weeds. Allelopathy of wheat (Triticum aestivum L.) has been extensively examined for its potentials in weeds management. The al-lelopathic activity of wheat has been attributed to hydroxamic acids, the related compounds and phenolic acids. Therefore, it could effectively reduce herbicide uses in order to maintain an eco-friendly environment and a cost-effective weed control.

“…Th e principal method to control weeds is the use of synthetic herbicides (Hong et al 2004). Although these products have brought unquestionable gains to agriculture, their use increases production cost, reduces crop quality (resulting in less healthy plants and more expensive food) and, contaminates the environment, which is a threat to human and livestock health (Silva et al 2005).…”

Allelopathic eff ects of orange (Citrus sinensis L.) peel essential oil RESUMO (Efeitos alelopáticos do óleo essencial da casca da laranja (Citrus sinensis L.)). Plantas daninhas são o principal problema da agricultura no mundo, causando anualmente um prejuízo de U$95 bilhões. A principal forma de combate às plantas daninhas são os herbicidas sintéticos. Entretanto, o uso continuado desses produtos encarece a produção, reduz a qualidade dos alimentos, deixa resíduos tóxicos no ambiente e ameaça a saúde humana e animal. Existe assim, uma demanda por técnicas menos agressivas de controle. O uso de compostos alelopáticos de descartes de culturas para esse fi m é uma alternativa. A laranja é uma das maiores culturas do mundo, e gera grandes quantidades de resíduos. Existem evidências da bioatividade no óleo essencial da casca da laranja. Nesse trabalho, nosso objetivo foi verifi car a existência de propriedades alelopáticas desse óleo. Para isto, extraímos o óleo por arraste de vapor de água utilizando o aparelho de Clevenger, e colocamos os produtos volatilizáveis do óleo essencial em contato com plântulas de Euphorbia heterophylla L. e Ipomoea grandifolia (Dammer) O'Donell. O resultado foi inibição tanto quantitativa quanto qualitativa das plântulas Palavras-chave: agricultura orgânica, alelopatia, controle de pragas, descartes de cultivos, Limoneno, plantas invasoras de culturas Jose Pedro Nepomuceno Ribeiro 1,2 and Maria Inês Salgueiro Lima 1 ABSTRACT (Allelopathic eff ects of orange (Citrus sinensis L.) peel essential oil). Crop weeds are the main problem in agriculture, causing a worldwide annual loss of about US$95 billion. Th e principal method for control is the use of synthetic herbicides. Th e continued use of these products increases crop costs, reduces crop quality, and leaves toxic residues in the environment, which are a threat to human and livestock health. Th erefore, there is a demand for environmentally friendly methods of weed control. Th e use of allelopathic compounds from crop residues is an alternative. Orange is one of the biggest crops in the world, and its cultivation generates large amounts of residues. Th ere is strong evidence of bioactivity in orange peel essential oil. Th erefore, the objective in this work was to verify the allelopathic proprieties of this oil. We extracted the oil from the peels of recently discarded oranges using water vapor fl ow with a Clevenger extractor, and tested it against the growth of Euphorbia heterophylla L. and Ipomoea grandifolia (Dammer) O'Donell seedlings when placed in contact with the oil vapor. Th e results were both quantitative and qualitative in the inhibition of the seedlings.
