  • Seasonal dynamics of net photosynthesis and productivity of Spagnum papillosum
    Gaberščik, Alenka ; Martinčič, Andrej
    Seasonal dynamics of net photosynthetic activity, growth and chlorophyll content of the peat moss Sphagnum papillosum Lindb. has been studied in a raised bog near Ljubljana (Slovenia, Yugoslavia). ... Generally, no correlations were recorded between the annual course of net photosynthesis and the growth dynamics. Maximum values of net photosynthesis were achieved in August (1.95 mg CO2 g -1 h -1), when the rate of biomass accumulation decreased. At the beginning of the growing season, growth in dry weight was intensive. During the winter months photosynthetic activity declined and in February it was completely interrupted. Chlorophyll content varied markedly during the sampling period. Chlorophyll content was positively correlated with net photosynthesis, but not with growth. In 1984, 3.3 cm growth in length and 20 mg plant-1 increase in dry weight were recorded.
