Plant activation of barley by intercropped conspecifics and weeds: allelobiosis

摘要

Experiments with components of a barley cropping system are summarised in a tritrophic context with reference to allelochemical communication between undamaged plants. The results are discussed with regards to different mechanistic explanations. Withreference to the different roles of allelochemicals in plant/plant communication in a "winner-loser" perspective, it is suggested that the term "allelobiosis" is used to denote this type of interaction.
