Abstract

As part of the Austrian MAB-6-project "Obergurgl" net primary production of a Caricetum curvulae and reproduction strategies of the dominating phanerogams were investigated. The present paper deals with production efficiency of the canopy, and sterage ability of phanerogams in respect to their production and reproduction. During one vegetation period, a total amount of energy of 2.5 to 3.0 MJ.m. a is absorbed| about one half is bound by the aboveground biomass, the other half by the belowground biomass. The efficiency of the net primary productivity amounts about 0.27% for the length of a production period (105-128 days).
