Abstract
The relationship between cumulative frequency of cankers caused by N. galligena and the age of the tissue when the canker became established on the main stem was sigmoidal in Betula lenta, B. papyrifera, Juglans nigra and Sassafras albidum. The point of change in the curve from exponential to logistic was at 3 yr for J. nigra, 5 yr for B. papyrifera and 7 yr for B. lenta and S. albidum.This publication has 0 references indexed in Scilit:
