Sažetak
Significant areas of land formerly used in Lika, due to cessation of agricultural production are covered with bracken (Pteridium aquilinum (L.) Kuhn.), opening the way for vegetation succession to the forest stage. The aim of this study was to determine the competitiveness of two forage crops in these areas with the aim of suppressing and crowding out bracken. The experiment was performed in vitro in which the seeds of tall fescue (Festuca arundinacea Schreb.) and red clover (Trifolium pratense L.) were treated with extract of bracken, Pteridium aquilinum. We measured the number of germinated seeds and the length of plumule and radicle. The results show a decrease in germination of red clover for 2%, respectively tall fescue by 31%. Radicle length in red clover was reduced by 33.1%, while the reduction in length at tall fescue was 66.7% for radicle and 51.1% for plumule. This study confirmed allelopathic inhibitory effect of bracken extract on red clover and tall fescue germination and primary development. The data suggest a potentially large losses in efforts of introduction of these crops through sowing on bracken fields, which especially applies to tall fescue.
