W lasach gminy Szadek i terenów przyległych stwierdzono 9 stanowisk kwitnącego i owocującego bluszczu pospolitego. Odnotowano na nich 195 kwitnących okazów tego gatunku. Związane są one z siedliskami średnio żyznymi i żyznymi. Najczęściej notowano je w grądach, rzadziej w łęgach. Podporami dla kwitnących okazów Hedera helix najczęściej są: Alnus glutinosa, Quercus robur oraz Pinus sylvestris. Większość stanowisk związana jest z brzegami lasów lub leśnymi drogami. Głównymi czynnikami stymulującymi zakwitanie bluszczu są „ocieplanie się” klimatu oraz fragmentacja powierzchni leśnych.

Forest typological and phytososological biodiversity of forest vegetation of Slobozhansky National Park is shown. The park covers 5244 hectares and includes the main parts of the run off valleys of the left-bank Merla River tributary, which belongs to the Vorskla River basin in the Kharkiv region. The main forest-forming species of the Slobozhansky National Nature Park are Pinus sylvestris L. (2779.3 hectares, 59.84%), Quercus robur L. (1451.8 hectares, 31.26%). Minor areas are occupied by Betula pendula Roth (138.3 hectares, 2.98%), Alnus glutinosa (L.) P. Gaertn. (122.5 hectares, 2.64%), Populus tremula L. (45.0 hectares, 0.97%) and other species. Areas covered with forest vegetation are represented by 16 edatopes: all trophotope and almost all hygrotopes, except very dry. Among the trophotopes subors (2015.2 hectares, 43.39%), oak wood (1504.4 hectares, 32.39%) and sugruds (1042.2 hectares, 22.44%) predominate, and the part of pine forest is insignificant (82.5 hectares, 1.78%). Among hygrotopes, the majority are with fresh conditions (4060.6 hectares, 87.43%), much smaller areas are dry (268.4 hectares, 5.78%), damp (184.3 hectares, 3.97%), moist (124.4 hectares, 2.68%) and wet (6.6 hectares, 0.14%) conditions. There are 17 types of forests in the Slobozhansky National Park areas covered with forest vegetation. Fresh oak-pine forest (1780.6 hectares, 38.35%), fresh maple-linden forest (1453.6 hectares, 31.30%), fresh linden-oak-pine sugrud (756.8 hectares, 16.30%) are dominated. Pinus sylvestris plantations grow in 10 forest types. The most common types of pine forests are fresh oak-pine and fresh linden-oak-pine sugrud. Quercus robur growth in 7 forest types, the most common of which is fresh maple-linden oak wood. The distribution of forest typological differences on the territory of the park of vascular plants rare species populations, which have different sozological status is analyzed. Annex I to Resolution 6 of the Berne Convention includes the following species: Dracocephalum ruyschiana L., Jurinea cyanoides (L.) Rchb., Iris pineticola Klokov. A number of species have the appropriate conservation status in Ukraine (Diphasiastrum complanatum (L.) Holub, Lycopodium annotinum L., Dracocephalum ruyschiana, Pulsatilla pratensis (L.) Mill. Sl, Allium ursinum L., Iris furcata M. Bieb., Iris pineticola, Fritillaria meleagris L., F. ruthenica Wikstr., Tulipa quercetorum Klokov & Zoz, Epipactis helleborine (L.) Crantz, Listera ovata (L.) R. Br., Neottia nidus-avis (L.) Rich., Platanthera bifolia (L.) Rich., Stipa borysthenica Klokov ex Prokudin) and 22 species at the regional range.

Pine Stands

Mature  Scots pine (Pinus sylvestris  L.) stands are dominating large parts of the Flemish forest area. Broadleaved  species regenerate spontaneously under this pine canopy. This study studied  the growth and development of two planted pine stands with an older natural  regeneration, dominated by pedunculate oak (Quercus  robur L.), and discussed management options for  similar stands.     The results indicated a rather good growth of the stands, with current  annual increments of 5 m3.ha-1.yr-1. The pine overstorey is growing into valuable sawwood  dimensions, while the broadleaved understorey slowly grows into the  upperstorey. The quality of the regeneration is moderate but can be improved  by silvicultural measurements (pruning, early selection).     In both stands, an interesting (timber production, nature conservation)  admixture of secondary tree species is present in the regeneration. Stand  management is evolving from the classical clearcut system towards a  combination of a type of selection and group selection system.

Abstract Selected forestry parameters were investigated in the system of tree vegetation and wood-destroying fungi in parks of the Kyiv city along a gradient of recreational transformation. We investigated vitality, age structure and health conditions of woody plants (Acer platanoides L., Aesculus hippocastanum L., Carpinus betulus L., Frangula alnus Mill., Pinus sylvestris L., Quercus robur L., Q. rubra L., Sambucus nigra L., Tilia cordata Mill.), and species, systematic, trophic and spatial compositions of xylotrophic fungi (27 species of xylotrophs representing 22 genera, 16 families, 6 orders of divisions Basidiomycota; class Agaricomycetes). The results showed that the communities of tree vegetation and xylotrophic fungi in parks depend on the degree of recreational transformation of the environment. Vitality, age structure and health conditions of trees altered species composition of xylotrophs.

Abstract The aim of the study was to evaluate the possibility of using botanic antifeedants to reduce the damage caused by Melolontha spp. grubs. To achieve the objective, the experiments were established in semi-field conditions to estimate the antifeedant activity of rutin, quercetin (flavonoids from buckwheat Fagopyrum esculentum) and an extract from black alder Alnus glutinosa leaves against Melolontha melolontha grubs. The grubs were placed individually in the pots with a soil in which 2 year old Pinus sylvestris trees were planted. The pots were put in garden pavilions placed in the open area. Then the soil in the pots were watered with the emulsions of rutin, quercetin, an extract from A. glutinosa leaves, and with pure water-comparative variant. After 4 months, the weight and mortality of grubs were compared, as well as the weight of tree roots in all pots. There was no effect of the antifeedants on the development and extent of damage caused by M. melolontha grubs. The results do not indicate the use of botanic antifeedants in the protection of forests against the cockchafer grubs

Phytotoxic Activity

The results of the study of phytotoxic effects of water extracts from Pinus sylvestris L., Betula pendula Roth, Quercus robur L., Picea abies (L.) Karst. P. excelsa Link, Carpinus betulus L., Robinia pseudoacacia L., Populus tremula L., Crataegus submollis L. are presented. For а comparison of the phytotoxic activity of the investigated plants was used to measure the change in the intensity of the mitotic division, depending on the concentration of aqueous extraction of plant material (tangent trend curve of cytostatic activity). According to this parameter, the following row of phytotoxic activity of wood species can be ordered: Populus tremula, Betula pendula, Robinia pseudoacacia, Carpinus betulus, Acer platanoides, Tilia cordata, Pinus sylvestris. Water extract Quercus robur and Picea abies have discovered a phyto-stimulating effect. The results of the study allow us to discuss the possibility of introducing the parameter of the phytotoxicity coefficient to determine the allelopathic effect in the tree-tree system.
