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 non-dormant. Sterilize seeds before placing them on wet germination paper. Then germinate under an alternating temperature regime of 15/20ºC (the higher temperature for 16 hours of light and the lower one for 8 hours of dark).
Morphology
Fruit: Nut
Seed: Nutlets ovoid-ellipsoid, dorsal side convex, ventral side angular with indistinct rib, areole (Whitish hilum at the base) straight. Surface smooth, lustrous, dark brown.
Seed size: Seed length: 1.2-1.7, width: 1-1.5 mm in an accession from Bardsir, Kerman with 1000 seed weight 0.3 g, which was collected in 2014 by Ghonchaee, and the cultivated sample was identified by Ziba Jamehzad with accession number 41251.
1000 seed weight: 0.3 g.
Biological features
Life form: Perennial, many-stemmed, woody at the base.
Inflorescence and flower type and pollination mechanisms: Inflorescence closely spaced verticillasters, spike-like in the upper part, one separated verticillaster in the lower part. Flowers hermaphrodite, zygomorphic, corolla light blue, 10-12 mm long. Plant monoecious, cross-pollinate. Pollination is carried out by insects.
Flowering Period: Summer
Time of seed ripening: August to October
Seed dispersal methods: The seeds are displaced by weight.
