The Effect of Low-input Grassland Management on Arnica montana L. Species in Apuseni Mountains, Romania

摘要

Arnica montana is a valuable medicinal plant, protected all over in Europe, which grows in mountain area. Some of the most important areas of grassland with this species in Europe are located in Romania, in the area of Apuseni Mountains. By this paper we meant to study the possible effects of different cutting frequency on the evolution of Arnica Montana sp. Our studies were carried out in the Apuseni Mountains, in Garda de Sus village area. In order to meet our objectives, we proposed one experimental area with 5 variants in 5 repetitions. The experimental area was set as follows: V1 - abandoned meadow, V2 - traditional mowing, V3 - early mowing, V4 - mowing twice, V5 - grazing simulation by repeated mowing. Mowing was done gradually, taking into consideration the experimental protocol established, on a period between June and October.?? Harvesting was done in August, using a rotary mowing machine. Floristic composition was analyzed with special attention on the evolution of Arnica montana , according to the applied management measures. The results showed that there were significant differences on Arnica montana L. production as a result of the applied management.
