Chlorophyll and pheophytin content in needles of different age of trees growing under conditions of chronic industrial pollution
Chlorophyll and pheophytin content was determined by means of Vernon method (Vernon, 1960) in needles of different age. Needles of Pinus strobus L., Pinus nigra Arnd., Pinus silvestris L., and Pseudotsuga menziesii Franco growing under conditions of chronic industrial pollution as well as under unpo...
