allelopathy

Allelopathy involves the production of secondary metabolites from plants, which affects the growth of neighboring plants and microorganisms either by inhibiting or by promoting their growth.

Effects of eucalyptus allelopathy on growth characters and antioxidant enzymes activity in phalaris weed.

This reduction in corn density may have been due to the greater early season density of yellow mustard compared with the other smother plant species or the allelopathy often associated with Brassica species (Al-Khatib et al.

scientists to explore allelopathic phenomena, calls the new work "excellent," noting that many biologists have argued about the theory of plant allelopathy but few have actually designed ways of documenting it.

The alternative hypothesis that chemical allelopathy (e.g., the unique compound avrainvilleol) might be responsible for inhibition of epiphytic growth (cf.

The use of specific crop and cover crop rotations may also be used to control pests through allelopathy an interference interaction in which a plant releases into the environment a compound that inhibits or stimulates the growth or development of other organisms.

Previous research suggested that pale swallowworts might be putting phytotoxins into the soil to discourage the growth of competing plants nearby--a process known as "allelopathy." But the specific compounds responsible for pale swallowwort's toxic effects had not been identified.

Such allelopathy is found in black walnut tree roots.

Allelopathy involves plant chemical interactions in both natural and agro-ecosystems.

Beyond direct competitive interactions, goldenrods have the potential to interact indirectly with their neighbors through allelopathy. Allelopathy has generally come to mean the deleterious effect that one plant has on another through the production of chemical retardants (Martin and Rademacher, 1960; Muller, 1965; Jackson and Willemsen, 1976).
