FEASIBILITY STUDY TO PRODUCE AIR-POLLUTANT-PHILIC PLANTS BREEDING THEIR NO_2-ASSIMILATION ABILITY BY THE TRAINING PROCEDURES DEDUCED BY THE BIOELECTIC POTENTIAL SIGNAL MEASUREMENT AND ANALYSIS.

本文介绍了一种在屏蔽舱内测量植物叶片生物电位信号的系统。还建立了一个子系统，用于精确控制温度，湿度，本文对3200片木棉花叶片在不同浓度NO_2污染物下的生物电位信号和NO_2同化能力进行了测定和分析，结果表明，木棉花叶片的生物电位信号与NO_2同化能力的瞬态曲线吻合得很好。2叶片周围的气体密度。研究表明，生物电位信号可以用来评价植物对NO_2污染的同化能力或自我保护能力，并对利用生物电位信号的测定和分析，通过诱导培养程序，创造出增强植物同化NO_2能力的"嗜NO_2植物"的可行性进行了探讨。这一结果有力地表明，我们可以通过上述方法，对"乡土和野生种"中的优势亲NO_2性状进行选择育种，创造出"亲NO_2植物"。

A ststem has been developed for measuring bio-electric potential signals on the leaves of plants housed in a shielded cabin. A subsystem has also been built for precise control of temperature, humidity, light intensity and the density of the NO_2-pollutant in the cabin.Bio-electric potential signals and NO_2-assimilation ability have been measured and analyzed for 3200 leaves of plants (Kapok) at various levels of the pollutant density.The transient profiles of the bio-electric potential signals are coincident well with those of NO_2 gas density around the leaves. It has been revealed that bio-electric potential signals are available enough to evaluate NO_2-assimilation or self-protecting ability of the plants against NO_2-polluted air.Feasibility study has been made to create "NO_2-philic plants" reinforcing the NO_2-assimilation ability by the training procedures deduced from the information obtained through the measurement and analysis of the bio-electric potential signals.This result strongly suggests that we can create "NO_2-philic plants" by selective breeding of the prepotent NO_2-philic property in the "Native and wild species" by means of the procedures mentioned above.
