This Seed <\/strong>ID<\/strong> was supported by the <\/strong>Headquarters of Science and Technology of Medicinal Plants and Traditional Medicine<\/strong><\/p>\n

Seed Storage <\/strong><\/p>\n

The storage behavior of this species is orthodox (desiccation-tolerant seeds), dry to 15-20% eRH, and store at -20\u00b0C.<\/p>\n

\u00a0<\/em><\/strong><\/p>\n

Germination<\/strong> requirements<\/strong><\/p>\n

The seeds of this species are not dormant. Sterilize seeds before placing them on wet germination paper. Place seeds for two weeks at 4 \u00baC to germinate uniformly. Then germinate under an alternating temperature regime of 15\/20 \u00baC (the higher temperature for 16 hours in light and the lower one for eight hours in dark).<\/p>\n

Morphology<\/strong><\/p>\n

Fruit type:<\/strong> Achene<\/p>\n

Fruit shape: <\/strong>Subcylindric, weakly compressed laterally, apex truncate, pappus rough, brown creamy at base, longer than the achene, outer bristles shorter than interior, innermost bristles cream-colored, short and scaly; hilum sub-lateral. Surface glabrous, with some longitudinal faint striate, slightly lustrous, pale straw-colored<\/p>\n

Fruit size:<\/strong> Length 5.87 to 6.04 mm, width 3.11 to 3.32 mm in an accession from Hamedan, with 1000 seed\/fruit weight 21.3 g, which was collected and identified in 2017 by Mohammad Mahmoodi, and is stored in the Natural Resources Gene Bank of Iran with the accession number 46950.<\/p>\n

1000 seed\/ fruit weight: <\/strong>18.9 to 24 g<\/p>\n

 <\/p>\n

Biological<\/strong> features<\/strong><\/p>\n

Life form: <\/strong>Subshrub, perennial. Stem erect, 40 to 70 cm height, pubescent<\/p>\n

Inflorescence, flower type, and pollination mechanism:<\/strong> Inflorescences solitary capitate, capitulum disciform; florets yellowish white or creamy, outer florets filiform; inner florets tubular; involucre ovoid, involucral bracts multiseriate. Plant monoecious, \u200ccross-pollinated. Pollination is carried out by insects and wind.<\/p>\n

Time of flowering:<\/strong> Mid spring to early summer<\/p>\n

Time of fruit\/ seed ripening:<\/strong> Mid spring to early summer<\/p>\n

Fruit\/ seed dispersal methods:<\/strong> The agent of seed distribution is seed weight and animals.<\/p>\n

Geographical distribution<\/strong>: <\/strong>Endemic to Iran. Typus from Jarob Mountain near Mardabad<\/p>\n

Distribution in Iran:<\/strong> West and Center. Mostly in provinces Hamedan, Lorestan, Isfahan and Tehran<\/p>\n
