A 2014-2018 között megvalósult „KASZÓ-LIFE” program keretében élőhely rehabilitáció történt a KASZÓ Zrt. területén, enyves éger (Alnus glutinosa (L.) Gaertn.) és kocsányos tölgy (Quercus robur L.) állományokban. A területen vízvisszatartó létesítmények segítségével próbálják csökkenteni, illetve lassítani a talajvíz süllyedését, javítani az erdők talajának vízháztartását, és ezen keresztül az erdők egészségi állapotát. Az erdők egészségi állapotának megfigyelésére mintaterületeket jelöltünk ki, ahol évente két alkalommal rögzítettünk adatokat. Az adatokat összevetettük a talajvíz, csapadék és meteorológiai mérések eredményeivel. A rendszeres egészségi állapot felvételezésekkel felmértük a bekövetkezett változásokat, és meghatároztuk a területen rendszeresen előforduló kárformákat és ezek kiváltó okait. Az eddigi vizsgálatok adatai azt mutatják, hogy mind a tölgyek, mind az égerek esetében 2017-től már kisebb mértékű javulás jelentkezett a kontroll területekhez képest. Ugyanakkor a vizsgált időszak relatív rövidsége miatt még nem lehet egyértelmű következtetéseket levonni a program sikerességéről, de a megfigyelések folytatásával erre is lehetőség nyílik a jövőben.

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.)

AbstractDuring spring, utilising multiple cues allow temperate tree species to coordinate their bud burst and leaf out, at the right moment to capitalise on favourable conditions for photosynthesis. Whilst the effect of blue light (400-500nm) has been shown to increase percentage bud burst of axillary shoots of Rosa sp, the effects of blue light on spring-time bud burst of temperate deciduous tree species has not previously been reported. We tested the hypotheses that blue light would advance spring bud burst in temperate tree species, and that late-successional species would respond more than early-successional species, who’s bud burst is primarily determined by temperature. The bud development of Alnus glutinosa, Betula pendula, and Quercus robur branches, cut from dormant trees, was monitored under two light treatments of equal photosynthetically active radiation (PAR, 400-700 nm) and temperature, either with or without blue light, under controlled environmental conditions. In the presence of blue light, the mean time required to reach 50% bud burst was reduced by 3.3 days in Betula pendula, 6 days in Alnus glutinosa, and 6.3 days in Quercus robur. This result highlights the potential of the blue region of the solar spectrum to be used as an extra cue that could help plants to regulate their spring phenology, alongside photoperiod and temperature. Understanding how plants combine photoreceptor-mediated cues with other environmental cues such as temperature to control phenology is essential if we are to accurately predict how tree species might respond to climate change.Key MessageAn LED spectrum containing blue light advanced bud burst in branches of Betula pendula, Alnus glutinosa and Quercus robur compared with a spectrum without blue light in a controlled environment.

Abstract Markovskaja S., 2012: Aero-aquatic fungi colonizing decaying leaves in woodland swampy pools of Aukštadvaris Regional Park (Lithuania) (Oro-vandens grybai kolonizuojantys pūvančius lapus užpelkėjusiose miško balose Aukštadvario regioniniame parke) - Bot. Lith., 18(2): 123-132. Comparatively high diversity of fungi (26 species) decomposing leaf litter were found in small lentic habitats (swampy pools) in mixed Gubiškiai Forest of Aukštadvaris Regional Park. Together with widespread aquatic and terrestrial fungi, 14 species of aero-aquatic hyphomycetes were found colonizing freshly fallen leaves of Quercus robur, Tilia cordata and Alnus glutinosa in autumn 2011. Of these, six species, Ardhachandra cristaspora,Candelabrum spinulosum, C. clathrosphaeroides, Dactylaria fusiformis, Helicodendron tubulosum and Xylomyces giganteus were recorded for the first time in Lithuania. In addition, a noteworthy new aero-aquatic fungus, preliminary placed in the genus Pseudospiropes by morphological characterization, was found on decaying leaves of Quercus robur. New records to the country and rare species are illustrated, their morphological and ecological peculiarities are discussed herein.

U ovome radu analiziraju se kvalitativna svojstva peleta izrađenih iz vrsta drva turopoljskog kraja – sadržaj pepela, ogrjevna vrijednost, gustoća peleta i tlačna čvrstoća. Prikupljeni su uzorci hrasta lužnjaka (Quercus robur L.), običnoga graba (Carpinus betulus L.), poljskog jasena (Fraxinus angustifolia Vahl.), crne johe (Alnus glutinosa L.) i crne topole (Populus nigra L.). Prikupljeni i okorani uzorci usitnjeni su na mlinu s noževima na granulaciju 2,00 mm. Na uzorcima je ispitan sadržaj vode, pepela i ogrjevna vrijednost. Sadržaj pepela određen je zasebno za koru i drvo. Sadržaj pepela u kori pokazuje visok udio kod hrasta lužnjaka koji iznosi 13,64 % i graba sa 11,91 %, dok je kod ostalih vrsta udio pepela u kori između 7 i 10 %. Sadržaj pepela okoranog drva pokazuje vrijednosti 0,63 % za hrast, 0,50 % za jasen, 0,46 % za grab. Vrijednosti sadržaja pepela kod johe i topole bile su oko 0,4 %. Rezultati ukazuju na potrebu okoravanja u proizvodnji peleta s ciljem postizanja kvalitete peleta klase A1 i A2. Određivanjem ogrjevne vrijednosti najbolji rezultati utvrđeni su kod uzorka drva crne topole koja iznosi 19,63 MJ/g, a najmanja vrijednost izmjerena je kod uzorka graba 18,94 MJ/g. Nadalje, navedeni uzorci pomiješani su te su fomirane 3 grupe mješavina. Udio tvrdih vrsta listača hrasta, graba i jasena u svakoj pojedinoj mješavini bio je 60 % dok su u preostalom udjelu od 40 % jednoliko sudjelovale joha (20 %) i topola (20 %). Formirane mješavine materijala JTJ (jasen 60 : topola 20 : joha 20), HTJ (hrast 60 : topola 20 : joha 20) i GTJ (grab 60 : topola 20 : joha 20) prešane su u pelete uz pomoć hidrauličke laboratorijske preše pri 2 veličine sile (3,0 i 6,0 kN) i 2 temperature (150 i 200 °C). Po isprešanju, peleti su ostavljeni 15 dana da se dimenzijski stabiliziraju te su im određene dimenzije i gustoća. Peleti su potom ispitani na tlačnu čvrstoću u radijalnom smjeru pomoću kidalice. Peleti iz svih mješavina, prešani silom 6,0 kN kod temperature 200 °C pokazali su visoku gustoću koja je bila u rasponu 1 207 – 1 234 kg/m<sup>3</sup>. Peleti osnovne mješavine jasena dali su kod sile 3,0 kN i temperature 200 °C vrlo visoku gustoću od ≈ 1200 kg/m<sup>3</sup>, dok su općenito najmanju gustoću imali peleti osnovne mješavine graba kod svih režima prešanja. Rezultati tlačne čvrstoće u radijalnom smjeru pokazuju najbolje rezultate kod peleta prešanih pri 6,0 kN i 200 °C i to 13,59 MPa kod osnovne mješavine jasena, 11,1 MPa mješavine hrasta i 9,06 MPa mješavine graba. Ako se tlačna čvrstoća peleta promatra zbirno prema mješavini, značajno bolje rezultate daju peleti izrađeni iz mješavine jasena, topole i johe u usporedbi s ostale dvije mješavine.
