Introduction of Allium giganteum regel and its biochemical composition in culture

The purpose of research is to study the characteristics of biology (phenology, morphological parameters, reproduction), yield and biochemical composition of leaves under culture conditions. The experiment was carried out at the collection site of the laboratory of wild flora and the introduction of herbaceous plants in 2015-2022, the plants were grown from seeds obtained in 2014 from Lithuania (Tartu). Phenoritmotype is a short-vegetating spring-early summer flowering ephemeroid. It grows in the 1st-2nd decade of April. Morphometric parameters: arrow length - 113.0 ± 4.74 cm; arrow thickness - 0.9 ± 0.09 cm; leaf length - 40.7 ± 4.04 cm; sheet width - 5.5 ± 0.62 cm; inflorescence diameter - 6.1 ± 0.27 cm; flower diameter - 1.2 ± 0.04 cm. In the inflorescence of A. giganteumi there are on average 146.0 ± 17.55 pcs. flowers, fruits - 91.5 ± 22.69 pieces, umbel fruiting - 58.3 %. Real seed productivity per shoot is 260.0 ± 81.02 pcs. seeds, potential seed production - 876.0 ± 105.27 pcs., the number of seeds in the fruit - 2.7 ± 0.27 pcs.; fetal seedification - 45.3 %, umbrella productivity coefficient - 28.2 %. The leaves revealed: 144.0 mg% ascorbic acid; 6.62 mg/kg carotene; 3.32 mg/kg starch; 4.1 % sugar; 1.94 % protein; 0.35 % fat; 0.31 % nitrogen. From macronutrients, the content of calcium and sulfur was found to be 0.02 %; phosphorus - 0.05; potassium - 0.15 %; from trace elements: cobalt - 0.08 mg/kg; copper - 1.37; manganese - 2.79; zinc - 11.50 mg/kg (based on wet weight). Reproduction is by seed, the absolute weight of seeds is 4.0 g. Over the years of study (2015-2022), A. giganteum has shown itself to be a winter-hardy, resistant plant.
