Couldn't resist adding to the 'nolige' base
is the inhibition of growth of a plant due to biomolecules
released by another. It is the opposite of symbiotic mutualism
. The biomolecules are called allelochemicals
and are produced by some plants as secondary metabolites. When the allelochemicals are released into the environment, they inhibit the development of neighbouring plants.
I assume the post expands the definition to include non plant species can excrete chemicals that will inhibit neighbors from being able to utilize compounds necessary for existence?
