Shadow alliums at the introduction in the South-Ural Botanical Garden-Institute

Abstract

Results of introducing studying of three shadow species of Allium L. genus: A. microdictyon, A. ursinum , A. victorialis : biometric parameters, seasonal rhythm of growth and development, seed efficiency and features of reproduction are given. For A. ursinum and A. victorialis data on vitamin C content are provided. These alliums are biologically close among themselves and integrated under the general name rampson. The studied species of alliums differ in parameters: diameter of a bulb ( A. ursinum - up to 1 cm, A. victorialis - up to 2 cm, A. microdictyon - up to 1.5 cm), height of a peduncle ( A. ursinum - 22-28 cm, A. victorialis - 48-55 cm, A. microdictyon - 46-58 cm), arrangement of leaves on a plant ( A. ursinum leaves are located at the shoot’s base, A. microdictyon and A. victorialis , - up to 1/2 or 1/3 parts of a stalk), quantity of leaves on a generative shoot ( A. ursinum - 2 pieces, A. microdictyon and A. victorialis - 2-3 pieces), an inflorescence ( A. ursinum has a semi-spherical umbrella, A. microdictyon and A. victorialis - a spherical dense umbrella), diameter of an inflorescence ( A. microdictyon - 4 cm, A. ursinum - 4.7 cm, A. victorialis - 4.4 cm). According to the seasonal rhythm, these plants are short vegetating, short flowering ones. The studied species go through all stages of life cycle, are stable in culture and are perspective for cultivation in Bashkir Cis-Urals (northern forest-steppe).
