Growth responses of red pine seedlings to the chemical bioregulator, DCPTA


Journal Article

The chemical bioregulator, 2-(3, 4-dichlorophenoxy)-triethylamine (DCPTA), which has markedly stimulated photosynthesis, carbon allocation, and above- and below-ground growth of several agricultural crops, caused small growth effects on red pine (Pinus resinosa L.) germinants and one and two-year-old seedlings, mainly to foliage and stems. At low DCPTA concentrations, i.e. 10 ppm, growth tended to be promoted, whereas at 100 ppm growth appeared to be suppressed. Continued testing of the bioregulator's effect on growth and physiology of other tree species is recommended. © 1987 Martinus Nijhoff Publishers.
