Abstract
This report explains the intervessel pit dimension of Populus tomentiglandulosa and its role in embolism repair according to proposed mechanism by Zwieniecki and Holbrook, 2000. It was found that mean contact angle (θ) of water droplets on the inner surface of vessels was 56°. Openings into the bordered pits were typically elliptical. The angle of the bordered pit chamber (2α) was found 142.17°. From the capillary equation ΔPmax =γGcos (θ+α), it was found that mathematically the maximum pressure 0.08MPa created by pits, can be employed to force the air within the embolized vessel into solution.
