Every month during the course of a year, content of chlorophylls a and b and of carotenoids was tested spectrophotometrically in needles of cultivated black pine trees (Pinus nigra Arnold) from three localities distinguished by their pollution levels, tree ages and soil concentrations of Mg and Fe. Pigment content fluctuated, increasing during the summer and decreasing during the autumn months, and tended to correlate negatively with pollution level. There was a possible effect of tree age on pigment content. The chlorophyll a : b ratio varied independently of pollution level and locality.
