ALLIUM PORRUM IN THE SOUTH-URAL BOTANICAL GARDEN- INSTITUTE
The results of introduced studying of Allium porrum L.: a seasonal rhythm of growth and development, seed productivity, features of reproduction are given in the article. On terms of blossoming A.porrum treats middle-summer, on blossoming duration - to short- blossoming plants. The phase of blossoming of individual of A.porrum by years lasts 14-17 days. The period from the beginning of growth before maturing of seeds by years is 133 - 152 days. The nature of vegetation - long-vegetative, summer-green, with winter rest and summer semi-rest. The real seed productivity (RSP) of one umbrella makes 1952 pieces of seeds, the potential seed productivity (PSP) - 3443 pieces of seeds, number of seeds in a fruit - 3,5 pieces, a fruit semenification - 58%. RSP is lower than PSP on 1,8 times. Potential opportunities of umbrella are implemented for 57%. In the conditions of the culture self-sowing was not observed. The coefficient of vegetative reproduction makes 1-1,2. Laboratory viability of seeds - 56%. Weight of 1000 pieces of seeds - 3,94 g. The winter hardiness was 30-50%. The number of individual in artificial populations decreases every year. Ontogenesis of A.porrum in artificial populations is only 4-5 years. By results of introduction it is carried to group of unpromising plants. One of ways to keep A.porrum in a collection as an ornamental plant is a periodic renewal by its crops of seeds. For receiving vitamin greens in the conditions of the Bashkir Cis-Urals A.porrum can be grown up (as one-year culture) at crops in soil or through seedling.
