Utilisation of species-rich Bromion grasslands as donor sites for regional seed mixtures
Original language description
The utilisation of species-rich grasslands as donor sites for regional seed mixtures was tested in a Bromion meadow located in the White Carpathian Mts. (Czech Republic). The seed was harvested with a brush harvester in two methods: a) once only (H1) andb) three times per site (H3). Seed number and weight were assessed from seed samples. In H3, the number of seeds per 1 m2 of grassland was significantly higher in the first harvest (164.8) than in the second (36.3) and third (22.4) harvests. The high number of seeds found in method H1 (162.6) was not significantly higher than in the early harvest of method H3. In terms of weight, the greatest amount of seed was harvested on the first date of method H3 (0.327 g), when the mixture contained 78% grasses.On all other dates the amount of seed was significantly lower, and forbs (including legumes) were the predominant fraction in the samples, i.e. 74% (H1), 62% (H3 - 2nd harvest) and 91% (H3 - 3rd).
