1.用2,4-D处理植株后其原生质粘度有较显著的变化;并且,这些变化依着於用2,4-D的浓度而转移。2.喷洒2,4-D后,当植株在形态上还未曾表现出任何变化的时候,而在原生质粘度的变化上却已经有相当明显的反应了。3.在刺激的剂量下(本测定中以1.5ppm开始到10ppm为止)喷染24小时后皆降低了植株的原生质粘度。而在抑制的剂量下(本测定由20ppm开始),植株均提高了原生质的粘度。4.在刺激的剂量下植株虽然暂时的降低了它的粘度,但是经过10天以后我们发现这些植株的粘度又重新提高了。而在抑制或伤害的剂量下,植株原生质的粘度始终是提高着的。
1. There was a more significant change in the viscosity of the protoplasm after 2,4-D treatment of the plants; and, these changes were attributed to 2,4-D concentrations. After spraying 2,4-D, when the plant morphology has not shown any changes in the time, but the changes in the viscosity of the protoplasm has been quite a clear response. 3. Reduced plant protoplasm viscosity 24 hours after spaying at stimulated doses (starting from 1.5 ppm to 10 ppm in this assay). At the suppressed dose (starting from 20 ppm in this assay), the plants increased the viscosity of the protoplasm. 4. Although the plant temporarily reduced its viscosity at stimulated doses, after 10 days we found that the viscosity of these plants was again increased. In the suppression or injury dose, the plant protoplasm viscosity is always increased.
