Vegetative buds and current-year mature needles harvested from a single Norway spruce
(Picea abies), grown in the Botanical Garden at the University of Kiel (Germany), were …

Vegetative buds represent developmental stage of Norway spruce (Picea abies L. Karst.)
needles where chloroplast biogenesis and photosynthetic activity begin. We used the …

Fifteen-year-old Norway spruces (Picea abies [L.] Karst.) were grown in open top chambers
(OTC) at ambient (A) and elevated (ie ambient+ 350 μmol (CO2) mol− 1) concentrations of …

Gymnosperms, unlike angiosperms, are able to synthesize chlorophyll and form
photosystems in complete darkness. Photosystem I (PSI) formed under such conditions is …

Both chlorophyll a and b and polypeptides of the photosynthetic apparatus are found in
gymnosperm seedlings. germinated and grown in absolute darkness. The photosystem II …

The photosynthetic performance of developing spruce (Picea abies L. Karst.) needles was
investigated. As revealed by previous reports, the biosynthesis of chlorophylls and …

Plants acclimate to ambient light by modifying a number of physiological processes,
especially those that aff ect the efficiency of light harvesting and use. When light level is …

Winter-induced inhibition of photosynthesis in Scots pine (Pinus sylvestris L.) needles is
accompanied by a 65% reduction of the maximum photochemical efficiency of photosystem …

Inhibition of photosynthesis was followed during autumn and early winter in current-year sun
and shade needles of unfertilized and fertilized Norway spruce [Picea abies (L.) Karst.] by …

It has been suggested in previous papers that air pollution may render plants more
susceptible to photoinhibition [Krause, GH Physiologia Plantarum (1988) 74, 566-574] …
