Summary Introduction

To describe:

The observation that supports the hypothesis that the water is pulled through the trunk as a result of transpiration. Measurements of the tree trunk diameters indicate that the trunk shrinks during the day, with shrinkage occurring in the upper part of the trunk before it occurs in the lower part.

Introduction:

Transpiration is the process of water movement in the plant and the process of evaporation from the aerial parts of the plants. The transpiration is the driving force that pulls water up from the roots to the leaves and other parts of the plant.
