比电导率通常用于确定冷处理后植物的抗冻能力。这项研究的目的是确定葡萄树（Vitis vinifera L.）气生器官比电导率的演变与其在所应用的处理方面的生存能力程度之间是否存在相关性。数据显示两种类型的增加：第一种是在没有任何治疗的情况下随着物候演变观察到的，而第二种是在对器官进行治疗后出现的。这种增量在芽处比在枝条处更强。经过霜冻处理的器官的电解质泄漏似乎与它们对寒冷的敏感性或所应用的处理的强度有关。
Specific conductivity is often used to determine plant freezing tolerance after a cold treatment. This study was undertaken to determine if there is a correlation between the evolution of aerial organs specific conductivity in vine (Vitis vinifera L.) and the extent of their viability with regard to the applied treatment. The data show two types of increases: the first one was observed along with the phenological evolution, in absence of any treatment, whereas the second appeared after the treatment on the organs. This increment was stronger at the bud than at the-shoot level. Electrolyte leakage from the frost treated organs seems to be linked with their sensitivity to cold or the intensity of the applied treatment.
