Bioassays and field studies for allelopathy in terrestrial plants: Progress and problems

From: Critical Reviews in Plant Sciences | Date: January 1, 2003| Author: | Copyright information

ABSTRACT: Bioassays are an integral part of allelopathy research. The unsuitability of laboratory bioassays to explain field situations is discussed previously. In this article, we discuss progress in bioassay experimental design and several unresolved problems associated with research on allelopathy. The objectives of this article are to discuss problems related to (1) collection of allelopathic material for bioassay, (2) allelochemical quantification in bioassays, (3) selection of concentration of allelochemicals in bioassay, (4) selection of appropriate control, (5) interaction between ...
