Relationship between transpiration and cambial activity inAbies balsamea

摘要

Using an antitranspirant (abscisic acid) and a transpiration promoter (Floralife), a positive correlation was found between the rates of transpiration and cambial activity in cuttings of balsam fir,Abies balsamea(L.) Mill. Differences in transpiration rate were not due to differences in xylem production.
