Influence of the sowing date and state of secondary transformations of moorsh formations on the Lolium perewne seed germination in the condtions of pot xperiments was studied. Peaty moorshes (Zi) and proper moorshes (Z2) with granular structure'taken TrönTTFe peat-moorsh soils at various stages of the moorshing process were used in the present experiment. Two levels of soil moisture were applied. It was found out that the influence of the sowing date on the differentiation of darnel emergencies on the moorsh soils was not big. However, a clear tendency for better germination of the seeds sown in summer than those sown in spring was observed. It was especially visible on the granular moorsh formations (Z3) that were not able to create as favourable water conditions for darnel seed germination and development of seedlings as peat moorshes (Zi) because of poor abilities for water conductivity. The present experiment showed that in order to ensure darnel emergencies on the soils formed of granular moorshes it is necessary to keep their moisture level close to 80% of their full water capacity. Seed germination was influenced more by the kind of moorsh and its moisture level than by the status of secondary transformation of the moorsh mass and sowing date.
