Study on the Relationship between Changes of Water in Stem and Incidence of Canker Disease during the Early Stage of the Planted Poplars

  • Received Date: 1991-08-01
  • In the early stage of the planted Poplars,the changes of relative water content in cortex,xylem or trunk are different.For the cutting top Poplars and the checks,the change of relative water content in xylem is the biggest,and that in the cortex the smallest.Before the spread of the leaves,the main water loss is due to the trunk transpiration.The surface of the cutting top Poplar is smaller than that of the check,so the water loss in the treated Poplar is less than that of the check.This is one of of main reasons why the incidence of the Poplar canker disease was reduced in the cutting top Poplar plantation.

Abstract: In the early stage of the planted Poplars,the changes of relative water content in cortex,xylem or trunk are different.For the cutting top Poplars and the checks,the change of relative water content in xylem is the biggest,and that in the cortex the smallest.Before the spread of the leaves,the main water loss is due to the trunk transpiration.The surface of the cutting top Poplar is smaller than that of the check,so the water loss in the treated Poplar is less than that of the check.This is one of of main reasons why the incidence of the Poplar canker disease was reduced in the cutting top Poplar plantation.
