摘　　要：为了能通过介电参数的检测,快速鉴别植物的生长状况。通过试验研究了橡胶苗离体叶片的生理电容和生理电阻与测量频率、测量电压的关系。试验结果表明,400Hz为较适宜的测量频率,而测量电压间无显著差异。且随着叶片离开植株时间的增加,叶片的电容值减少,电阻值增加。In order to efficiently distinguish the growth condition of the plant through the dielectric parameter examination,thisexperimental study the relationship between the rubber seedling exsomatize leaf's physiological electric capacity,physiological resistance and the frequency,measurement voltage.The test result indicated that 400Hz is the suitable test frequency,and there is no remarkable difference among the measurement voltages.And with the time that the leaves separate from the plant increasing,the physiological electric capacity is reduced, and the physiological resistance is increased.
