A new experiment method was proposed to examine the effect of low oxygen concentration stress on plant roots. Air of low oxygen concentration was generated by mixing air and nitrogen gas. Container made from polypropylene was used as growth tube for germination and growth of pea seeds (Pisum sativum L. cv. Alaska). It has two mouthpieces for inflow of air and low oxygen concentration air. It has five mouthpieces for outflow of these air on opposite site of these. Air (20.9% oxygen concentration) on upper part and air of low oxygen concentration air (10.4%) on lower part was flowed into growth tube, respectively, at the rate of 50 ml per minute. As a Vaseline-paraffin paper was set in container as a partition, oxygen concentration of these outflow air from upper part and lower part were 20.4 and 10.6%, respectively. Pea seeds were germinated, and their roots were growing up and penetrating to the vaselin-paraffin paper.
