Abstract

Electrolytic leakage in infected Blue pine (Pinus wallichiana) needles was monitored by measuring conductivity change in pine needles affected by Lophodermium needle blight disease. Electrolytic leakage in infected Blue pine needles varied significantly between severity categories. Highest electrolytic leakage of 345.33 µmoh/cm was noticed in pine needles having > 81% disease severity in comparison to unaffected check (181.33 µmoh/cm) indicating a positive relationship between disease severity and electrolytic leakage. The evaluation of electrolyte leakage appears to be rapid and accurate method for assessing the hardwood seedling health and physiological status.

 

Key words: Electrolytic leakage, blue pine, needle blight.
