Comparative analysis of efficiency of reproduction grades of Hyacinthus x Hybridus Hort. of collections of the Central Botanical Garden by method of preparation of bulbs

English. Hyacinthus x hybridus Hort. appears one of the most effective spring bulb flower plants. Collection of the Central Botanical Garden consists of more than 90 varieties of the plant. The main goal of the introduction of different varieties of Hyacinthus appears not only formation of the collection but comparative evaluation of the sorts, selection of the most perspective one for wide cultivation in the conditions of the Republic of Belarus. The article evaluates coefficient of vegetative propagation of different sorts of Hyacinthus x hybridus Hort. from the collection of Central Botanical Garden during propagation of prepared bulbs and suggests selection of the varieties with high coefficient of vegetative propagation. The result of the preparation of 67 varieties of Hyacinthus x Hybridus Hort. as the most effective method of increasing the coefficient of vegetative propagation is presented. Average coefficient of vegetative propagation of the sorts of Hyacinthus of different garden groups during dissection of the bottom is calculated. It is revealed that depending on the groups variations compose from 7 to 59 units.

Russian. Цель нашей работы – определение коэффициента вегетативного размножения (КВР) сортов гиацинта гибридного из коллекции Центрального ботанического сада при размножении препарированием луковиц, а также отбор сортов с высоким КВР, перспективных для получения отечественного посадочного материала. В статье представлены результаты препарирования 67 сортов гиацинта гибридного как наиболее эффективного метода повышения коэффициента вегетативного размножения. Выявлено, что в зависимости от сорта и группы коэффициент варьируется от 7 до 59 единиц.
