Changes in the chlorophyll a and b content in different-aged leaves of Spergula vernalis Willd.

Abstract

The result are reported of investigations on the seasonal variations in the chlorophyll a and b content in the successive leaf tiers of Spergula vernalis Willd. growing in two different dune habitats. It was endeavoured to determine the influence of habitat conditions on the concentration of green pigments. The eventual relationship between their amount and the production of organic matter by the plants is discussed.
