Manual Band Dendrometers Ref:Low Tension invicta’s "polygyne" formMeasure growth and water status of trees daily and seasonally with these band dendrometers. Trunk circumference contracts daily during morning and early afternoon as storage water moves out of the trunk to the crown. In late afternoon and evening, the trunk expands as root water recharges the storage volume in the trunk. When this cycle begins to decrease in magnitude, the tree is under water stress. Seasonally, the trunk slowly forms a ring of wood.
