Acquisition of the joining degree information by measuring the electric potential of the grafted seedling and development of the recuperating and acclimatizing system.

植物电生理领域是近几年才建立起来的，并没有被认为是一个完整的学习领域。它只是停留在公用事业方面。顺便说一句，针对近年来果实营养嫁接苗木大量生长的需求，正在开发嫁接机器人等自动育苗系统。在植物工厂的理念下，考虑到粮食问题和环境问题，植物生产系统的进步引起了人们的关注。活植物的信息必须以非侵入性的方式测量，并具有微妙的信号，以便能够在之前预测变得清晰。活体电位仪是实现这一目的的有效方法。本研究涉及的生理指标是嫁接苗的接合度。本研究的目的是开发利用测量电势…获取连接度信息的疗养习服系统更多的是嫁接苗的L。2000年：第一年就研制出了一套可以测量苗木电势的系统。设计制作了电位仪环境控制箱、电位计传感器探头和计算机放大、A/D转换、记录仪等电路。2001年，第二年试行了通过测量嫁接苗电势来获取嫁接苗的接合度信息。本试验以番茄幼苗为材料，采用剪根嫁接法，在适宜的嫁接时期进行嫁接。修剪后的砧木，与接合度相对应，促进生根。测定的项目是根的数目、根的总长度以及砧木茎表面与含有根系的基质之间的电势差。采用的培养条件有：蛭石、泥炭-苔藓和水。电极的正极固定在料杆的杆轴上，负极固定在介质上。将置于电极上的幼苗转移到环境控制箱中，每隔一分钟测量一次暗期间和光期的电势。人们认识到，光周期的电势幅值比暗周期的电势幅度大。计算了不定根在各种基质和各种光照条件下的发育状况与电势的相关系数。从这一结果可以看出，在测量和使用蛭石和水作为介质的早期，相关系数较高。较少

A plant electric physiology field whichi created in recent years, isn`t recognized as a completed learning field. It has just been stuck on the utility side. By the way, sutomatic system of the seedling production such as a grafting robot is being developed against the demand for fruit-vegetative grafted seedlings to be grown greatly recently. The advance of the plant production system draws attention under the idea of the plant factory in consideration of the food problem and the environmental problem. Information of the alive plant has to be measured in non-invasive with a delicate signal to be able the be predicted before to become clear. The method of living body electric potential instrumentation is useful for that aim. The physiology handled in this research is the joining degree of the grafted seedling. The pupose of this research is the development of the recuperating and acclimatizing system using acquisition of the joining degree information by measuring the electric potentia … More l of the grafted seedling.In 2000 years : A system which could measure the electric potential of the seedling, was fabricated in the first year. The environment control box to measure the electric potential, the sensor probe for the electric potential measuring and the electric circuit such as an amplifier, an A/D change device, a record device by the computer were designed, producted, examined.In 2001 years : Acquisition of the joining degree information by measuring the electric potential of the grafted seedling was tried in the next year. Materials for this experiment are the tomato seedlings which joined with the pruned root cutting grafting method in suitable period for grafting. The root formation of the stock which is pruned root, is promoted corresponding to joining degree. Measurement item are the number of adevetous roots, the total length of them and the difference in electric potential between the surface of the stem of the stock and a medium which is contained a root system. There medium conditions were employed such as vermiculite, peat-moss and water. The plus pole of an electrode is fixed on the stem shaft of the stock, and the minus one is on a medium. The seedlings which electrodes were put on were transferred in the environment control box, and the electric potentials of them were measured in every one minute for both a dark and a light period. It was recognized the tendency that the electric potential amplitude is wider in the light period than in the dark one. The correlation coefficients between the development condition of advetitious roots and the electric potential were calculated in every medium and in every light condition. From that result, the cases obtained a high correlation coefficient were in the early period during measuring and using vermiculite and the water as a medium. Less
