Abstract
Differently aged needles from a Pinus nigra Arnold tree growing in a typica l urban area have been examined by means of electron paramagnetic resonance (EPR) spectroscopy, and the variation of the observed six-line Mn (II) sig nal was monitored for 1 year. An inverse trend has been established between the photosynthetic efficiency of the plant and the measured content of Mn (II). The possibility of using EPR spectroscopy in studying ageing and in a ssessing stress situations in plants is considered.
