| Abstract: | Summary Marigold (Tagetes patula L.) contains secondary metabolites toxic to various organisms. While these compounds may function as defensive agents in
the plant, it is not clear whether they are exuded into the rhizosphere. Using a continuous root exudate trapping system and
capillary column gas chromatography/mass spectrometry/data system, four thiophenes and two benzofurans were identified in
the root exudates collected from the undisturbed rhizosphere of marigold. The importance of rhizospheric chemistry in the
study of allelopathy is stressed. |
