TО BIOLOGY OF ALLIUM PLATYCAULE IN SOUTH-URAL BOTANICAL GARDEN-LNSTITUTE

Abstract

The introduction study of Allium platycaule S. Wats. was cani.ed out: seasonal rhythm of growth and development, seed productivity, reproduction, the characteristic of age states of initial stages of ontogenesis and assessed the success and perspective of the species under the culture аге given. А. platycaule is а short-vegetative ephemeroid plant with early flowering. In seed reproduction, the generative state occurs at 6 year of vegetation. Flowering occurs in early June, the duration of flowering Ьу year is 12-17 days. The seeds mature in early July. The vegetation lasts about 2,5 months. From 15 to 30 flowers form in the inflorescence. The fmit formation of the umbrella varies from 26 to 89 % Ьу years. The real seed productivity of 1 umbrella averages 25,4 pieces of seeds. The fmit contains an average of 2 pieces of seeds. The efficiency coefficient of umbrella ranges from 8 to 40%. The potential opportunities аге realized Ьу an average of 200/о. The natural vegetative reproduction coefficient is 3,5. Weight of 1000 seeds - 4,9 g. Winter resistance is good, attacks afterreengineering were not observed. According to the assessment of introduction resistance, А. platycaule is а promising plant.
