| Název: | Influence of seed´s biological traits of oat next seed generation in organic farming |
| Abstrakt: | In organic farming, there has been a longtime deficiency of certified organic seeds. Therefore, oat was used as a model crop in order to demonstrate results of the assessment of particular biological traits of various seed categories (certified organic, conventional untreated, farm). The seeds’ biological traits (energy of germination, germination, energy of emergence, emergence, thousand grain weight - TGW) were assessed before seeding and the impact of the seed quality on the grown seeds was studied. Plot trials including four varieties of naked and hulled oat were set up in three localities in the Czech Republic between 2010 and 2011. As for the quality of the seeds serving for the establishment of the plot trials, the conventional untreated seeds proved the highest energy of germination (86.3%), germination (88.3%), energy of emergence (72.8%), emergence (79.1%) and TGW (31.9 g). As for the organic seeds, these originating from the certified organic crop stands proved the highest quality for the energy of germination (90.4%), the germination (92.6%), the energy of emergence (79.4%), the emergence (85.8%) and the TGW (30.8 g), just as these originating from the farm crop stand the energy of germination (90.2%), the germination (88.3%), the energy of emergence (79.2%), the emergence (85.4%) and the TGW (30.4 g). The energy of germination, the germination and the energy of laboratory emergence were (p<0.05) influenced by a locality. The correlation analysis demonstrated a positive correlation (r = 0.65-0.95) between the parameters of hulled oat. Correlations between the TGW and the energy of emergence (r = 0.69), just as the emergence (r = 0.60), were also proved by the test. As for naked oat, close correlations were detected between the tested parameters of the germination and the emergence. The organic seeds originating from the certified organic crop stands proved the best biological characteristics. The farm oat seeds achieved a good qualitative level too. |
