Abstract:
437 bryosociological records of sereral agricultural localities of Mecklenburg were analysied. 81 moss species could be ascertained, floristical and plantgeographical investigations followed. The Riccio‐Anthoceretum, the Pottietum truncatae and the Pottieturn lanceolatae were found to be the most important communities. These associations are divided in subassociations, variants and subvariants. Ecological investigations showed, that the three mentioned associations differ in their claims to the p H, the calcium‐ and water content of the soil. While the Kiccio‐Anthoceretum prefers slight acid to acid, wet soils in the area influenced by the Atlantic, the Pottietum lanceolntae occurs on summerdry localities reacting alcaline in the southeast of Mecklenburg. The Pottietum truncataet the most abundant association grows especially on good agricultural localities (slightly acid to neutral, well soaked soils). The appearence of the various species in dependence on some ecological factors ( p H, K 2 O, P 2 O 5 and water content of the soil) is illustrated and they are classified in 7 sociologic‐ecologic groups together with a short characterisation of the localities. In cultnre experiments growth optinla and growth limits of some agricultural mosses are determined by variation of the acid degree, the potassium, phosphor and nitrogen content of the nutrient solution and by changing the water content of substrate. Comparing the experimental results with the ecologic claims of species showed, that the area of optimal physiologic growth is larger than that in which the species occur in the field. In the natural locality the area of possible growth (physiological growth area) is limited by competition. In addition to the ecologic investigations the nitrogen content of solution or of the soil may be estimated as further differentiating factor for the appearcnce of the three associations.
