Seed Storage
The storage behavior of this species is orthodox (desiccation-tolerant seeds); dry to 15-20% RH and store at -20 °C.
Germination requirements
The seeds of this species show non-deep dormancy. Sterilize seeds before placing them on wet germination paper. Place seeds two weeks in 4ºC to germinate uniformly. Then germinate under an alternating temperature regime of 15/20 ºC (the higher temperature for 16 hours in light and the lowest one for eight hours in dark).
Morphology
Fruit type: Legume
Fruit shape: Semiorbicular, slightly hairy, alveolate, crown segments obtuse, cartilaginous, denticulate
Seed shape: Reniform, seed coat smooth, yellowish–light brown
Fruit size: Length 12 – 14 mm, maximum width 6.5-8
Seed size: Length 3.4-4 mm, maximum width 2-3.5 mm in an accession from Khorasan with 1000 fruit weight 34 g, which was collected in 2001 by Mahmud Amirkhani, and the cultivated sample was identified by Hasan Amirabadizadeh with accession number 5784.
1000 fruit weight: 34 g
Biological features
Life form: Annual herb, erect
Inflorescences and flower type and pollination mechanisms: cymose 5-15 (-20) flowered, flowers hermaphrodite, zygomorphic and asymmetric; corolla (formed from banner: upper large petal, wings: two petals adjacent to the banner, and keel: two bottom petals) yellowish or brownish-purple, wings shorter than the keel; stamens are always ten in number, and their filaments are fused in a group of nine stamens plus one separate stamen (9+1). Plant monoecious, facultative cross-pollinate, which is carried out by insects.
