探讨了用电导法测定柿抗寒性过程中的若干干扰因素。结果表明，浸提液加水量和样品枝段长度与测定的电导值呈显著负相关，与电解质渗出率无关，但过长时间浸提后，不同枝段长度间电导值差异变小，电解质渗出率差异变显著。枝条顶端电解质渗出率较低，基端较高。中段介于２者之间。样品浸提时间在杀死前后以１２ｈ、５ｈ以后电导值趋于稳定。
Several disturbing factors in determining the cold resistance of persimmon by conductivity method were discussed. The results showed that there was a significant negative correlation between the amount of water added in the extract and the branch length of the extract and the measured conductance, but not with the electrolyte exudation rate. However, after prolonged leaching, the difference in conductance between different branch lengths became smaller. Exudation rate differences significantly. Electrolyte exudation at the top of the shoot is lower and the base is higher. The middle of the range between two. Sample leaching time before and after killing to 12h, 5h after the conductance value tends to be stable.
