Evaluation of cover crops in high tunnel vegetable rotation [PDF]

open access: yes, 2013
Organic vegetable production within high tunnels allows for an extended growing season, crop protection, and environmental control. The USDA National Organic Program (NOP) standards mandate evidence that the soil has been maintained and improved over the

Spatial heterogeneity promotes coexistence of rock-paper-scissor metacommunities

open access: yes, 2012
The rock-paper-scissor game -- which is characterized by three strategies R,P,S, satisfying the non-transitive relations S excludes P, P excludes R, and R excludes S -- serves as a simple prototype for studying more complex non-transitive systems.

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.

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 ...

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 ...
