Allelopathy as an evolutionary game

Plant Direct, 2022
In plants, most competition is resource competition, where one plant simply preempts the resources away from its neighbors. Interference competition, as the name implies, is a form of direct interference to prevent resource access.

Allelopathic Potential of Haloxylon persicum against Wheat and Black Mustard with Special Reference to Its Phytochemical Composition and Antioxidant Activity

Agronomy, 2021
Haloxylon persicum is a well-known plant of sandy deserts, but yet, its allelopathic and phytochemical potential has not been explored. In the present study, we evaluated the effects of different concentrations (1, 2, 4, and 8%) of the aqueous extract of

Plant Allelochemicals as Sources of Insecticides [PDF]

Insects, 2021
In this review, we describe the role of plant-derived biochemicals that are toxic to insect pests. Biotic stress in plants caused by insect pests is one of the most significant problems, leading to yield losses. Synthetic pesticides still play a significant role in crop protection. However, the environmental side effects and health issues caused by the

Allelopathic interactions between the macrophyte Egeria densa and plankton (alga, Scenedesmus acutus and cladocerans, Simocephalus spp.): a laboratory study

Journal of Limnology, 2016
Allelopathic interactions between macrophytes and zooplankton are important to understand the plankton dynamics in shallow waterbodies. Egeria densa is a native, perennial, submerged macrophyte in the tropical and subtropical zones of South America.
