Ursolic and oleanolic acids are secondary plant metabolites that are known to be involved in
the plant defence system against water loss and pathogens. Nowadays these triterpenoids …

Allelopathy in aquatic environments may provide a competitive advantage to angiosperms,
algae, or cyanobacteria in their interaction with other primary producers. Allelopathy can …

Characteristics of higher plant terpenoids that result in mediation of numerous kinds of
ecological interactions are discussed as a framework for this Symposium on Chemical …

Nitrification, a microbial process, is a key component and integral part of the nitrogen (N)
cycle. Soil N is in a constant state of flux, moving and changing chemical forms. During …

The phenomenon of allelopathy encompasses all types of chemical interactions among
plants and microorganisms. Several hundred different organic compounds (allelochemicals) …

Allelopathy is a process that can be present in many ecosystems, according to the literature.
Nevertheless, the authors think that, due to the evolutionary constraints, especially from a co …

Background Aboveground, plants release volatile organic compounds (VOCs) that act as
chemical signals between neighbouring plants. It is now well documented that VOCs emitted …

The effects of four monoterpenes—camphor, eucaliptol, limonene, and α-pinene—on the
oxidative metabolism of mitochondria isolated from maize root (Zea mays), on maize seed …

Monoterpenes, the main constituents of essential oils, are known for their many biological
activities. The present work studied the potential biological activity of twenty-seven …

Allelopathy plays an important role in the agroecosys-tems leading to a wide array of
interactions between crop-crop, crop-weed and tree-crops. Generally, these interactions are …
