Plants communication and drafting informational BA

从相互关系的观点来讨论植物的各器官之间或植物群中植物之间的通讯的研究几乎还没有。为了探讨这一问题，本研究通过考察不同个体间在环境反应和形态建成过程中是否存在同步现象，来研究BA的形成过程。根据申请表中报告的本研究的计划和方法，所获得的结果如下5点。通过对一组木棉叶片生物电位变化（交流信号）的长期测量，发现离体部位的部分叶片表现出相同的波形。这种现象也发生在一些叶子被切除的时候。这说明生物电势的变化是混沌的。当给予声刺激时，相关系数减小到2.5左右.利用一个能对生物电位（直流信号）进行长期测量的系统， ...更多信息 s）变化时，我发现表现出相似波形的树木形成群体。3.开发了一种新的测量系统，可以测量围绕根部自组织的电场变化模式。利用该系统，研究了光照、重力或障碍物刺激植物茎或叶时，植物根部周围的微弱电场是否发生变化。从实验中，我们已经发现，在所有情况下，电场图案被折叠和重组。这说明电场是植物根系与外界环境的自主界面，植物根系产生的信息是与外界环境相适应的.通过一种可以长期测量植物器官（叶、根、花瓣等）运动的系统，我同时测量了一片叶子和一根根的有节奏的运动。我发现，根和叶都表现出协同运动，周期约为2 [h]。另外，当两株植物相邻放置时，两株植物的根有节律地生长，且具有相位差，不会相互碰撞。在此基础上，探讨了BA发生过程中植物间的信息传递，并提出了一些关于信息BA的编制的认识。少

There has been almost no study made in which communication between each organ of a plant or between plants in a group was discussed from a view point of interrelationship. In order to investigate this problem, the process of BA fomation was researched by investigating whether synchronization phenomenon exists between individuals in environmental response and in morphogenesis or not. According to the plans and methods of this study which were reported in application form, the obtained results are following next 5 points.1. By making a long-term measurement of bio-electric potential changes (AC signals) of kapok leaves in a group, some leaves in seceded place showed same wave patterns. This phenomenon also happens when some leaves were excised. This shows that bio-electric potential changes in chaos. Furthermore, the correlation coefficient abates to about 2.5 when sound stimulation was given.2. By using a system which can make a long-term measurement of bio-electric potential (DC signal … More s) changes, I have found that trees showing similar wave patterns form groups.3.A new measurement system which can measure patterns of changes on electric field self-organized around a root was developed. By this system, I investigated whether feeble electric field around a root changes or not by stimulating a stem or a leave with light, gavity, or obstacle. From experiments, we have found that electric field patterns are collapsed and re-organized in all cases. This suggests that electric field works as the autonomous interface between root and external environment, and roots create informations which were adjusted to environments on ground.4. By a system which can make a long-term measurement of motions of plant organs (leaves, roots, petals, and etc.), I have simultaneously measured rhythmic motions of a leaf and a root. I have found out that both root and leaf showed cooperative motions with period of about 2 [h]. Additionally, when two plants were placed adjacent to each other, both roots grew rhythmically with phase difference to not to collide int each other.5. Based on obtained results, I examined the communication of plants in emergence of BA,and I have indicated some knowledge on drafting informational BA. Less
