On Allium obliquum L. biology and biochemistry in Bashkir Preural

Research presents the results of an introduction test of two samples of Allium obliquum L. (Bashkir, Siberian). Phenology, seed productivity, reproduction, agricultural technology and biochemical composition are studied. Phenorhythmotype is an early summer flowering short-growing hemiephemeroid. It grows in the 2–3rd decade of April. The budding phase – in the 2nd half of May, flowering – from the 1–3rd decade of June to the 1st decade of July. Duration of flowering of inflorescences is 8–12 days, individuals – 17–24 days. The seeds ripen in July – August. The period from regrowth to seed ripening is 92–105 days. The entire growing season lasts 115–125 days. The height of medium-sized plants of the Siberian sample is 104.9±6.26 cm, of the Bashkir sample – 99.6±5.68 cm. The number of flowers of one inflorescence in medium-generation plants of the Bashkir sample is 416.0±44.5 pcs., Fruits – 335 , 8±31.3 pcs., real seed productivity (RSP) – 995.5±80.4 pcs., productivity coefficient – 43.6±2.87 %; the number of flowers of one inflorescence of the Siberian sample – 392.0±35.18 pcs., fruits – 302.0±33.09 pcs., real seed productivity – 902.16±94.26 pcs. seeds, productivity coefficient – 39.5±3.45 %. The absolute weight of seeds is 2.4–2.5 g. The germination rate of seeds under winter sowing is 75–85 %, with spring sowing – 30–40 %. The coefficient of vegetative reproduction is 1–1.2. Biochemical composition of the Bashkirian sample: dry matter 16.54 %, nitrogen 1.97 %, crude fat 5.21 %, protein 12.3 %, starch 1.98 %, sugar 4.0 %, carotene 124.8 mg/kg, vitamin C 90.42 mg%; macronutrients: calcium 0.97 %, phosphorus 0.38 %, potassium 2.11 %, magnesium 0.20 %, sulfur 0.35 %; trace elements: zinc 89.1 mg/kg, iron 114.9 mg/kg, copper 5.4 mg/kg, manganese 59.4 mg/kg, cobalt 0.31 mg/kg. Biochemical composition of the Siberian sample: dry matter 16.61 %, nitrogen 3.21 %, crude fat 5.48 %, protein 20.06 %, starch 3.24 %, sugar 3.6 %, carotene 79.0 mg/kg , vitamin C 58.47 mg%; macronutrients: calcium 1.22 %, phosphorus 0.57 %, potassium 2.48 %, magnesium 0.29 %, sulfur 0.27 %; trace elements: zinc 181.5 mg/kg, iron 97.95 mg/kg, copper 14.5 mg/kg, manganese 15.4 mg/kg, cobalt 0.19 mg/kg.
