- W2756098350 abstract "Common ragweed (Ambrosia artemisiifolia L.) is a North American invasive alien species, which causes environmental and health problems. By virtue of the Slovenian law, landowners are committed to eliminate the plant. Before common ragweed becomes fertile, it is allowed to compost or throw away (into organic waste) the uprooted and mown plants. The main goal of the study was to examine the effect of composting and elevated temperatures which appear during the processing of the organic waste on the seeds. Fertile common ragweed plants were uprooted in the autumn, near the Ljubljana Railway Station (Slovenia). The plant fruits (nuts, containing one seed) were exposed to following treatments: a homemade composter along with 5 temperature treatments; 50 °C, 60 °C, 70 °C, 80 °C and 100 °C. The control group were the fruits preserved at room temperature. After the treatments, the fruits were put in the refrigerator for one month. After a superficial sterilisation of the seeds, a germination test was performed in petri dishes on moist filter paper. Germination of the seeds was surveilled for a period of three weeks. Due to the low germination rate, the test was performed again. After a given time in the second test, the seeds were transfered from petri dishes to a seed germinator containing soil.The germination rate within the first test was the highest in the control group, followed by the 50 °C treatment. The lowest germination rate in the first test was in the composter. In other temperature treatments, there were no seeds that germinated. In the second test, the highest germination rate was achieved in the composter, followed by the control group and lastly the temperature treatment of 50 °C. After the transfer of the seeds to the germinator with soil, another 3 seeds germinated: two from the control group and one from the 50 °C treatment.From the results of the experiment we can conclude that the seeds survive composting in the homemade composter. During the processing of organic waste, however, the temperature of 50 °C should be exceeded so that the seeds are destroyed, which is in accordance with the regulation." @default.
