Phytotoxic Substances Involved in Teak Allelopathy and Agroforestry

Teak (Tectona grandis L.f.) is one of the most valuable timber species, and cultivated in agroforestry systems many countries across tropical subtropical regions world. The species also essential trees home gardens South Asia due to its wood quality medicinal value folk remedies. It a deciduous tree amount litter that falls from teak huge. decomposition rate relatively fast humid conditions. interactions between weeds, or crops, under have been evaluated terms allelopathy. Evidence allelopathy documented literature over decades. leachate extracts leaves suppress germination growth several other plant species. Phytotoxic substances, such as phenolics, benzofurans, quinones, terpens, apocarotenoids phenylpropanoids, leaves, were isolated identified. Some phytotoxic substances may be released into soil leaf litters, which accumulate by annual fall can affect undergrowth allelopathic substances. potentially useful for weed management options agriculture reduce commercial herbicide dependency. was reported with enhance income through production crops woods, provide energy efficiency crop cultivation.
