Exposure of Avena sativa seedlings to unipolar ionized atmospheres of either charge produced statistically significant stimulation of growth as measured by mean stem length, integral elongation, and dry weight. The extent of growth increase was related to the atmospheric ion density and this in turn determined the magnitude of current flow to ground. The minimal current measured in the ground circuit and capable of producing a measurable difference in growth was 4.3 to 4.6 x 10(-13) amp/plant.
将燕麦幼苗暴露于由任何一种电荷产生的单极电离大气中,通过平均茎长、整体伸长和干重测量,均产生了具有统计学意义的生长刺激。生长增加的程度与大气离子密度有关,而大气离子密度又决定了流向地面的电流大小。在接地电路中测量到的能够产生可测量的生长差异的最小电流为4.3至4.6×10(-13)安培/株。
