ИНВЕНТАРИЗАЦИОННЫЕ ИССЛЕДОВАНИЯ ВИДОВДЕНДРОФЛОРЫ ХОРОЛЬСКОГО БОТАНИЧЕСКОГО САДА

Приводятся результаты инвентаризационных исследований дендрофлоры Хорольского ботанического сада, ее распределение за видовым, родовым, семейственным составом и за жизненными формами. Состоянием на 01.01.2018 года учтено 123 вида растений, которые в систематическом отношения принадлежат к 36 семействам и 76 родам. За биоморфологической структурой подавляющее большинство видов принадлежат к деревьям – 50 %, куст – дерево – 13 %, дерево – куст – 13 %, куст – 19 %, лиана – 5 %. Среди имеющихся видов доминирующей группой являются листопадные растения, что составляет 89%. Самые многочисленные за количеством видов семейства Rosaceae (27), Fagaceae (10), Juglandaceae (8), Sapindaceae (7). Такие семейства как Ginkgoaceae, Taxaceae, Anacardiaceae, Annonaceae, Araliaceae, Buxaceae, Celastraceae, Elaeagnaceae, Lythraceae, Myrtaceae, Ranunculaceae, Schisandraceae, Simaroubaceae, Tamaricaceae, Paeoniaceae представлены одним видом растений. В сравнении с данными 2011 года, а именно началом функционирования Хорольского ботанического сада выросли такие его количественные показатели дендрофлоры: видовой состав на 84 единицы, количество родов на 49, количество семейств на 19 единиц, голосеменных растений увеличилось на 14 видов.

INVENTORY INVESTIGATIONS OF SPECIES` COMPOSITION OF DENDROFLORA IN KHOROL BOTANICAL GARDEN

Khorol botanical garden – is a newly created research nature conservation establishment (it was founded in 2009 р., it has begun its activity since 2011 р., it was officially opened in 2013 р.), it is situated in the Khorol borders and occupies 18 hectares. Nowadays there is a collection of subtropical fruit crops, the crops of which are being growing in open soil, it was formed the collection of nut species and oaks and it was attracted the crops of ancient geological periods and the crops mentioned in the Bible to some collection planting. As a result it was created the research plot “The garden of subtropical fruit crops”, the expositional plot “Nut garden”, the thematic collections “Jurassic Park” and “Paradise Garden” та Райський сад, it was added some oak species to the oak grouping. A lot of tree and bush species of plants are being growing by specialists on seedlings locating on the territory of Botanical garden and outside of it with a purpose of further developing of collection plantings. The increasing quantity of wood and bush species of crops causes the inventory problem of species` composition of dendroflora in the botanical garden, the solving of which will give opportunity to estimate objectively its species composition of dendroflora in the botanical garden and realize the actions for further diversity. The aim of inventory investigations is to find out taxonomic composition of dendroflora in the botanical garden. The inventory investigations were naturally held during June and July by the observation method taking account common recommendations for inventory of green plantings. As an inventory research plan it was used cartographic materials about modern state of the territory of botanical garden (М: 1:1000) where road-alley network, reservoirs and other elements of internal situation are applied for carrying out of accounting actions. During field route examination it was estimated the species name of tree and bush crops and lianas according to morphological features by visual review of the crops by writing down the species name into a work-accounting book. The task was to clarify a species name of accounting tree-bush crops and lianas of nature flora and artificial plantings taking account their systematic. During inventory investigations it was found out that before January 2018 the dendroflora of Khorol botanical garden contains 123 species crops, belonging to 36 families and 76 species in systematic proportion. During inventory it was determined that the majority of species crops belongs to trees – 50 %, bush – tree – 13 %, tree – bush – 13 %, bush – 19 %, liana – 5 % according to bio morphological features. The leaf falling plants are 89%. They are dominate. There is an order of the most numerous families: Rosaceae (27), Fagaceae (10), Juglandaceae (8), Sapindaceae (7), Cupressaceae (5), Pinaceae (5), Salicaceae (5), Leguminosae (5), Betulaceae (5), Oleaceae (4). Such families as Ginkgoaceae, Taxaceae, Anacardiaceae, Annonaceae, Araliaceae, Buxaceae, Celastraceae, Elaeagnaceae, Lythraceae, Myrtaceae, Ranunculaceae, Schisandraceae, Simaroubaceae, Tamaricaceae, Paeoniaceae consist of only one crop species. Comparing the dates of 2011, when Khorol botanical garden was founded, the quantitative indicators of dendroflora have increased: species composition to 84 taxons, genus quantity to 49, family quantity to 19, bare seed crops to 14 species.
