This  study deals with the biomass estimation of the understory species of Pinus halepensis    forests in the Kassandra peninsula, Chalkidiki (North Greece). These  species are: Quercus    coccifera, Quercus ilex, Phillyrea media, Pistacia lentiscus, Arbutus  unedo, Erica arborea, Erica    manipuliflora, Smilax aspera, Cistus incanus, Cistus monspeliensis,  Fraxinus ornus. A sample of    30 shrubs per species was taken and the dry and fresh weights and the  moisture content of    every component of each species were measured, all of which were processed  for aboveground    biomass data. Then several regression equations were examined to determine  the key words.

Water Holding

Sphagnum mosses of three different species (S. capillifolium, S. magellanicum, and S. fallax) were allowed to dry in a controlled environment. The three species lost water at different rates, but after 11 days of exposure to drying atmosphere all were dry and unable to photosynthesize. The chlorophyllose cells of all three species showed signs of alteration, mainly membrane shrinkage. Upon rehydration, concentrations of photosynthetic pigments (chlorophyll a to a greater extent than chlorophyll b) declined in tissues of S. magellanicum and especially in S. fallax. Sphagnum capillifolium and S. magellanicum resumed photosynthesis, although slowly, whereas S. fallax did not achieve a net carbon gain (most of its chlorophyllose cells were irreversibly damaged) after 7 days of rewetting. In the field, prolonged drought may alter the interspecific equilibria among coexisting Sphagnum species possessing different degrees of desiccation-tolerance and especially different water-holding abilities. Keywords: Sphagnum, photosynthesis, ultrastructure, photosynthetic pigments, dehydration, rehydration.
