Hydrolysable Tannins and Biological Activities of Meriania hernandoi and Meriania nobilis (Melastomataceae)

open access: yesMolecules, 2019
A bio-guided study of leaf extracts allowed the isolation of two new macrobicyclic hydrolysable tannins, namely merianin A (1) and merianin B (2), and oct-1-en-3-yl β-xylopyranosyl-(1„-6’)-β-glucopyranoside (3) from Meriania ...

Density-dependent effect of allelopathy on germination and seedling emergence in two Ipomoea species

open access: yesRevista Chilena de Historia Natural, 2019
Background Density in inter and intraspecific plant-plant interactions affects the action modes of allelopathy (autotoxicity, negative and positive allelopathy). Some seeds exude compounds that inhibit the germination of others. Ipomoea murucoides and I.

Dose-Response—A Challenge for Allelopathy?

open access: yesDose-Response, 2005
The response of an organism to a chemical depends, among other things, on the dose. Nonlinear dose-response relationships occur across a broad range of research fields, and are a well established tool to describe the basic mechanisms of phytotoxicity ...

Investigation of the Allelopathic Effect of Two Invasive Plant Species in Rhizotron System

open access: yesLife
A key question in plant invasion biology is why invasive plants are more competitive in their introduced habitat than in their native habitat. Studies show that invasive species exhibit allelopathy, influencing other plants by releasing chemicals ...
