Study on 'Co-creation' and 'competition' in the group formation among plants

摘要

We investigated bio-electric potential changes of about 120 trees in a natural forest for a year continuously. As a result, it was found that a variety of clusters, which consisted of dozens of trees that showed similar daily-changing potentialwave-patterns, have been continuously forming independent of tree types. In addition, it was theoretically indicated that these cluster-formations are realized by a kind of entrainment action that came from chaos in the wave-pattern of bio-electricalpotential change. On the other hand, we examined rhythms in growth movements of pea radicles in a group and the electric field pattern, which is self-generated around the root, as a basic research of the co-creation mechanism. From the aforementionedfindings, it was found that the "competition" process was in existence during the group formation activity in addition to "co-creation" process.
