Seed Storage
The storage behavior of this species is orthodox (desiccation-tolerant seeds), dry to 15-20% eRH, and store at -20°C.
Germination requirements
The seeds of this species are not dormant. Sterilize seeds before placing them on wet germination paper. Place seeds for two weeks at 4 ºC to germinate uniformly. Then germinate under an alternating temperature regime of 15/20 ºC (the higher temperature for 16 hours in light and the lower one for eight hours in dark).
Morphology
Fruit type: Achene
Fruit shape: Sub-cylindrical or slightly obconic, compressed laterally, apex truncate, pappus dark brown-colored, pale brown at apex, slightly longer than the achene, outer bristles longer than interior, hilum sub-lateral. Surface glabrous, lustrous, with longitudinal faint striate, cream-colored
Fruit size: Length 5.44 to6.17 mm, width 2.75 3.42 to mm in an accession from Mahneshan, Zanjan, with 1000 seed/fruit weight 16 g, which was collected and identified in 2019 by Mohammad Mahmoodi and Esmail Jarchi, and is stored in the Natural Resources Gene Bank of Iran with the accession number 47013.
1000 seed/fruit weight: 16 to 26 g
Biological features
Life form: Subshrub, perennial, woody at base, pubescent. Multi stem, stems erect, 10 to 85 cm long
Inflorescence, flower type, and pollination mechanism: Inflorescences solitary capitate, capitulum radiate (disc-ray); florets red-purple, ray florets with sterile stamen; involucre sub-globose, involucral bracts multiseriate, involucral bracts arrangement free. Plant monoecious, cross-pollinated. Pollination is carried out by insects.
Time of flowering: Late spring to early summer
