Biological features of seeds of a wild-growing species of Poterium polygamum

Relevance . Biological features (morphometric indicators, viability and germinating power) of Poterium polygamum seeds found in natural communites the Stavropol Territory have been studied. The conservation wild-growing plant species population rational use their potential are relevant. Methods Years study — 2013–2021. subject is seeds. Seeds were collected 2013. Studies carried out according to methods studying seed material. Freshly harvested different shelf life germinated petri dishes at a temperature 18–20 °C. Results quite large. length 4–5 mm, width about 2.5 mm. mass 1000 pieces on average was 10.59 grams. Complete absence freshly revealed. After three months, 97%. This shallow physiological rest associated with post-harvest maturation period. During storage seeds, high germination established from 70 100%. duration 8 years. largest number power noted third year (100%). or fourth day. differences between not great. In eighth slightly reduced. period which they retain ability germinate power, long. It has that wild belongs plants (70 100%) viability. regularly resumed population. revealed biological can become scientific basis during reconstruction degraded grass stand selection work.
