Allelopathy and Its Role in Weed Management in Agriculture
Year: 2024
Type: article
Abstract: Allelopathy is a biological phenomenon in which an organism produces biochemicals, known as allelochemicals that influence the growth, survival, and reproduction of other organisms. In plants, allelopathy often refers to the release of chemicals by one plant that inhibit or promote the growth of neighboring plants. These allelochemicals can be released through various plant parts, including leaves, roots, bark, and seeds, and may affect nutrient uptake, germination, and overall plant health. Allelopathy plays an important role in natural ecosystems, agriculture, and forestry. It can help plants compete for resources; deter herbivores, and control pests and diseases. Some common examples include black walnut (Juglans nigra), which releases juglone to inhibit the growth of nearby plants, and allelopathic weeds like garlic mustard (Alliaria petiolata), which release chemicals that hinder native plant species.
