Historia parku i arboretum w Kórniku [The history of the Castle Park and the Kórnik Arboretum]
Tomasz Bojarczyk
The history of the Castle Park in Kórnik is more than 300 years old. The trees in the linden alley were planted about 300 years ago. In the middle of the XVIII century south of the Castle a big garden in the French style was established there. Since 1820 count Tytus Działyński gradually converted the Park into an Arboretum. From that period trees of Taxodium distichum, Liriodendron tulipifera, Juglans nigra, Ginkgo biloba, Pinus nigra, Abies cephalonica and Pseudotsuga manziesii have been preserved. This activity was continued by his son Jan Działyński, who bought many seeds and plants in well known nurseries in Western Europe. In the years 1927–1939 Antoni Wróblewski brought the Arboretum to its splendour expanding the collection of trees and shrubs. In the last decades the Arboretum has been significantly enlarged (up to 60 hectares, including the part in the Experimental Forest Zwierzyniec). Nearly 3,000 taxa of trees and shrubs are grow here now.

Zimowanie ukorzenionych sadzonek zielnych azalii gruntowych [Overwintering rooted cuttings of field grown azaleas]
Urszula Nawrocka-Grześkowiak
Further growth and development of rooted seedlings depends on way of wintering. Transplation of azalea to the flower-pots in autumn reduce percent of live plants in the spring. The best passing the winter are not transplanted seedlings, which are treated of variable temperature – first 0–5°C and from January 12–16°C. Applied of gibberellin in purpose of excite spring growth of seedlings is superfluous.

Rośliny wrażliwe na surowe zimy w kolekcjach dendrologicznych Ogrodu Botanicznego w Łodzi [Severe-winter sensitive plants in dendrological collections of Botanical Garden in Łódź]
Janina Krzemińska-Freda
Badania nad wrażliwością dendroflory Ogrodu Botanicznego w Łodzi prowadzono w latach 1986/87 i 1996/97. W ciągu tych dwóch surowych zim nastąpiło uszkodzenie mrozowe lub całkowite wymarznięcie niektórych gatunków obcych.
The climatic conditions, especially low temperature, strongly influence the cultivation of foreign flora in the open air. The dendroflora of the Łódź Botanical Garden consists of approximately 90 taxa of woody plants, which are mentioned in literature as frost sensitive species in central Poland. The symptoms of the tree and shrub damages caused by frost manifested themselves in necrosis of one-year-old shoots and previous year stems or in total destruction of the whole plant at ground level and in frozen leaves of evergreen plants (coniferous and leafed). Severe winter seasons in 1986/87 and 1996/97 resulted in the greatest losses in the dendroflora of our garden.

Kwiaty roślin iglastych z rodziny sosnowatych [Gymnosperm flowers from the Pinaceae family]
Joanna Blama
Kwiaty roślin iglastych są organami rozmnażania generatywnego. Są one rozdzielnopłciowe: męskie i żeńskie. Maja prosta budowę, niewielkie rozmiary, kwitną krótko. Z tych powodów przeważnie nie są dostrzegane przez ludzi. Jednak niektóre z nich, zebrane w kwiatostany o interesujących kształtach i intensywnych barwach, mogą być dużą ozdobą.
The conifers from the Pinaceae family Gymnosperm produce separate male flowers and female inflorescences. The construction of them is not complicated. They are rather small and have a short period of flourishing. On account of this feature people don’t always notice them. However some of them are very coloured and have an interesting shapes. They can have a decoration valour too.

Zróżnicowanie populacji Pinus mugo var. pumilio (Haenke) Zen. w początkowym okresie wzrostu [Population of Pinus mugo var. pumilio (Haenke) Zen. diversity at initial growth time]
Marcin Kolasiński
Pinus mugo var. pumilio (Haenke) Zen. – synonim P. montana var. pumilio Willk. – jest krzewem dorastającym do 1–2 m wysokości i 3 m szerokości. Charakteryzuje się powolnym wzrostem. Znana jest powszechnie duża zmienność w obrębie tego gatunku. Takie cechy jak siła wzrostu, liczba pędów na roślinie, a także długość igieł w istotny sposób wpływają na wartość użytkową odmian. Celem niniejszej pracy jest obserwacja zmian morfologicznych zachodzących w czasie wzrostu juwenilnego, ocena ich trwałości, oraz próba wyodrębnienia ciekawych form uprawnych. Przedstawiono graficznie wartości średnie długości igieł dla każdego osobnika. Zawierały się one w przedziale od 38 mm do 141 mm. Średnia długość igieł dla całej populacji ma wartość 76,5 mm. Drugą z badanych cech była długość jednorocznych przyrostów. Zawierała się ona w granicach od 1 do 12 cm. Badane osobniki wytwarzały od 1 do 45 pędów bocznych. Najczęściej miały ich jednak 7. Średnio w całej populacji stwierdzono 11,4 pędów przypadających na roślinę. Jedną z ważniejszych cech jest wysokość roślin. Roślina najniższa miała 4 cm wysokości, najwyższa 42 cm. Średnio cała populacja osiągnęła wysokość 19,7 cm.
Pinus mugo var. pumilio (Haenke) Zen. – Synonym P. montana var. pumilio Willk. – is a shrub growing to 1–2 m height and 3 m width. It is characterized by slow growth. Large variability within this species is well known. Such features as speed of growth, number of shoots on plant, and also length of needles can change its utility value. Present work aimed at observation of the morphological changes during juvenile growth, estimation their persistence, and selection of interesting cultivation forms. Values of mean length of needles for individuals graphically. The values ranged from 38 mm to 141 mm. Average length of needles for the population was 76,5 mm. The second feature tested was the length of one-year shoots. It ranged from 1 to 12 cm. Investigated individuals produced from 1 to 45 side shoots. Most of the individuals had about 7. Average for the whole population was 11.4 shoots on plant. One of most important features is height of plants. The lowest plant had 4 cm and the highest – 42 cm. Average for the population reached 19.7 cm.

Alternatywna technologia rozmnażania derenia jadalnego (Cornus mas L.) [Alternative technology of propagation cornelian cherry (Cornus mas L.)]
Stanisława Korszun, Marcin Kolasiński
Sadzonki półzdrewniałe derenia jadalnego ukorzeniano w tunelu foliowym umieszczonym w nieogrzewanej szklarni. W tunelu zamontowane było automatyczne zamgławianie. Z ponad pięćdziesięcioletniego krzewu matecznego pobierano sadzonki podwierzchołkowe, dwuwęzłowe, długości 10–12 cm. Stosowano nacinanie i nie nacinanie sadzonek wzdłuż pędu na długości 2 cm od ich podstawy. Sadzonki traktowano 1 lub 2% Rhizoponem AA. Do ukorzeniania użyto dwa podłoża różniące się składem komponentów i odczynem. Kombinację kontrolną stanowiły sadzonki nacinane i nie nacinane bez zastosowania stymulatorów wzrostu. Sadzonki bez zastosowania stymulatora wzrostu nie wytwarzały korzeni przybyszowych. Na procent i wzrost korzeni przybyszowych istotnie wpływało podłoże i stężenie auksyny IBA. Najlepsze wyniki (78–100%) uzyskano umieszczając je w mieszaninie torfu wysokiego i perlitu o pH w H2O – 5,0. Rhizopon AA 2% korzystnie wpływał na liczbę korzeni przybyszowych na sadzonkach.
Softwood cuttings of cornelian cherry were rooted in a polyethylene foil tunnel with automatic mist system placed in unheated greenhouse. Two-nodded, sub-apical, 10–12 cm cuttings were obtained from mother shrub over 50 years old. They were treated with Rhizopon AA containing 1 or 2% IBA. Cuttings were wounded or not. For rooting two different substrates with different component composition and acidity were used. Control combination were cuttings not treated with auxin. Cuttings without growth regulator treatment did not produce adventitious roots. Substrates and concentration of auxin influenced the percentage of rooted cuttings and roots length. Better results were reached in mixture of high moss peat and perlite with pH 5.0 in H2O. Rhizopon AA 2% promoted growth of adventitious roots of cuttings.

Nowa forma parrocji perskiej (Parrotia persica C. A. Meyer) rozmnażana za pomocą sadzonek [New form of Persian parrotia (Parrotia persica C. A. Mey.) propagated by softwood cuttings]
Stanisława Korszun
Na terenie Ogrodu Botanicznego Uniwersytetu im. Adama Mickiewicza w Poznaniu od 1975 roku rośnie nowa forma parrocji perskiej. Pochodzi ona z nasion otrzymanych z Suchumi. Różni się od innych krzewów parrocji barwą liści. Młode, rozwijające się liście początkowo są czerwone, następnie czerwony barwnik w dużym stopniu maskowany jest przez chlorofil. Już w drugiej dekadzie sierpnia liście ponownie przebarwiają się na czerwono. Doświadczenia z rozmnażania tej formy parrocji przeprowadzono w latach 2000–2001 w tunelu foliowym umieszczonym w nieogrzewanej szklarni. Sadzonki pół- zdrewniałe pobierano w drugiej dekadzie czerwca i ukorzeniano w mieszaninie torfu wysokiego i perlitu (w stosunku objętościowym 1:1) o pH w H2O – 5,0. Testowano wpływ stymulatorów wzrostu oraz podłoża wzbogaconego nawozem Osmocote Plus Mini na ukorzenianie się sadzonek. W zależności od zastosowanej kombinacji uzyskano od 6,6 do 90,0% ukorzenionych sadzonek. Badane czynniki wpływały również na długość i liczbę korzeni przybyszowych na sadzonce. Średnia długość korzeni przybyszowych oscylowała od 6,7 do 13,6 cm. Liczba korzeni przypadająca na sadzonkę była różna i wynosiła średnio 1,9–4,1, w zależności od zastosowanych czynników.
In University of Adam Mickiewicz’s Botanical Garden in Poznań since 1975 grows new form of Persian parrotia. Shrub was propagated from seeds received from Suchumi. It differs from other shrubs of parrotia with colour. New leaves are purple, later almost green. They discolour in purple again, already in second decade of August. An experience with reproducing this forms parrotia was conducted in years 2000–2001 in foil tunnel placed in unheated greenhouse. Softwood cuttings were taken in second decade of June and were placed in mixture of high peat and perlite (in volume ratio 1:1) about pH in H2O – 5.0. The influence of growth regulators and substrate enriched with Osmocote Plus Mini fertiliser on rooting ability and adventitious root quality was tested. Dependant on growth regulators used and rooting substrates enriched with a single dose of Osmocote Plus Mini fertiliser 6.6 to 90% of rooted cuttings were obtained. Examined factors influenced also on average length of roots (6,7–13,6 cm) and their average number (1.9–4.1).

Uprawa drzew z rodziny Taxodiaceae w regionie nadmorskim – Ogrodzie Roślin leczniczych Akademii Medycznej w Gdańsku [Cultivation of trees of Taxodiaceae in the Baltic coastal area – Medicinal Plant Garden of Medical University of Gdańsk]
Wojciech Cisowski, Maria Zielińska-Stasiek, Jolanta Zarembska
W niniejszej pracy przedstawiono charakterystykę rozwoju i uprawy drzew z rodziny Taxodiaceae, hodowanych w Ogrodzie Roślin Leczniczych Akademii Medycznej w Gdańsku. Prezentowane rośliny – egzemplarze młode, około 10-letnie, wchodzą w skład tworzonej w Ogrodzie kolekcji roślin drzewiastych i krzewiastych. Rodzina Taxodiaceae reprezentowana jest przez 5 rodzajów – Cryptomeria, Metasequoia, Sciadopitys, Sequoiadendron, Taxodium. W prowadzonych obserwacjach szczególną uwagę zwrócono na przechodzenie pełnego cyklu rozwojowego roślin oraz na ich odporność na wyniki biotyczne i abiotyczne, głównie przymrozki i mrozy. Z obserwacji wynika, że bardzo dobrym rozwojem i wzrostem w Ogrodzie odznaczają się: Sequoiadendron giganteum, Cryptomeria japonica, Metasequoia glyptostroboides i Sciadopitys verticillata. Bardzo trudno przystosowują się do warunków uprawy w pasie nadmorskim oba gatunki Taxodium: T. ascendens i T. distichum, które mimo 10-letniej aklimatyzacji wymagają dalszego okrywania na zimę. Bez perspektyw do uprawy w warunkach Ogrodu jest Cunninghamia lanceolata.
This paper presents the growth and development observations of several Taxodiaceae species cultivated from 1992 in the Medicinal Plants Garden (Medical University of Gdańsk). The Garden is located at the Baltic coastal area. The Taxodiaceae collection in the Garden consists of 5 genuses: Cryptomeria, Metasequoia, Sciadopitys, Sequoiadendron, Taxodium. All of them are young, about 10 year old trees. During the experiment the special attention was taken as for as the completed plant growth cycle was concerned. Besides, the plant resistance towards biotic, abiotic agent and ground frost was analysed. Plants, which showed the best growth in the Garden are: Cryptomeria japonica, Metasequoia glyptostroboides, Sequoiadendron giganteum and Sciadopitys verticillata. Two of analysed species Taxodium distichum and Taxodium ascendens are very difficult in getting used to Baltic coastal aerial climate conditions. Cunninghamia lanceolata is impossible to cultivate in the above conditions.

Kolekcja dendrologiczna Wojewódzkiego Parku Kultury i Wypoczynku w Chorzowie [Dendrological collection of the Voivodeship Park of Culture and Recreation in Chorzów]
Izabela Gerold, Adam Rostański
The Voivodeship Park of Culture and Recreation (Wojewódzki Park Kultury i Wypoczynku im. Gen. Jerzego Ziętka – WPKiW) in Chorzów is unique in its kind, since the park territory was laid out on a huge area (ca. 600 ha) of post-industrial wasteland. Actually the Park realises recreational and cultural functions and posses an interesting and diverse dendroflora. The studies were conducted during the years 1998-2001 in the WPKiW area. Present species composition of the dendroflora and frequency of occurrence of the taxa was analysed. The present dendroflora consist of 342 taxa of arboreal species, belonging to 208 species, 2 subspecies, 6 forms, 6 botanical varieties, 21 interspecific hybrids, 99 cultivars (cultivated varieties). Geographical analysis shows that 111 European species and 110 species of alien origin were found to occur within the territory of the WPKiW. Among the European species, 23 originate from southern Europe and 41 species represent eastern Europe. Among the 110 „alien” species – 49 are derived from North America and 61 from the Far East (south-eastern Asia). This results show that the Park in Chorzów possesses one of the largest and most interesting collections of trees and shrubs within the province of Silesia. This collection is rich and taxonomically diverse, abounding in specimens with interesting ornamental qualities. The WPKiW is undoubtedly a very valuable object from the natural and cultural point of view in the province of Silesia and it fulfils important ecological, leisure, social and also educational functions.

Badania porównawcze kambium piętrowego roślin drzewiastych występujących w kolekcjach ogrodów botanicznych w Polsce [Comparative studies of the storeyed cambium of woody plants present in collections of botanical gardens in Poland]
Wiesław Włoch, Paweł Kojs, Aleksandra Rusin, Waldemar Szendera, Jan Duda, Tomasz Rusin
Investigation of foreign species allows for the better understanding the essence of storeyed cambium. Dendrological resources of polish botanical gardens are very useful in these investigations. So far species regarded as possessing storeyed cambium were: linden and robinia. Their number actually appears to be higher, especially in collections of the introduced species and also among shrubs of the local flora. On the base of observations carried so far on the storeyed cambia one may await for the better understanding of the mechanisms explaining the rearrangement of cells, and for revealing the evolution of storeyed arrangement of cells in woody plants.

Od niefunkcjonalnej do funkcjonalnej piętrowości kambium. Modele piętrowości [From non-functional to functional storeyed arrangement in the cambium. Models of storeyed arrangement]
Paweł Kojs, Wiesław Włoch, Aleksandra Rusin, Waldemar Szendera, Jan Duda, Joanna Jura, Tomasz Rusin
Due to the fast change of the orientation of fusiform initials in a consequence of the horizontal rearrangement, trees with regular storeyed arrangement form interlocked grain, enabling fast growth of a tree in conditions of strong competition for light, with maintenance of the mechanical properties of a trunk. The described storied arrangement may be regarded as functional, in contrast to the storied arrangement which is limited to the small packets of cells, shifted against each other, and called non-functional in this article. This division may be useful in explanation of the mechanism of rearrangement: change of the inclination of fusiform cells in species with non-functional cambium would evoke the intensive intrusive growth, disordering storeyed arrangement in the cambium. In our investigation the horizontal rearrangement in the non-functional cambium was not observed so far; however it was shown that in the most of the investigated species the gradual reduction of storeys discontinuity is a consequence of vertical rearrangement, what leads to the formation of functional storeyed arrangement.

Indukcja i utrzymanie polarności w tkankach Zinnia elegans L. w kulturach in vitro [Induction and maintenance of the polarity in tissues of Zinnia elegans L. cultured in vitro]
Aleksandra Rusin, Paweł Kojs, Wiesław Włoch
The arrangement of tracheary elements and elongated parenchymateous cells reflects some aspects of tissue polarity. In some regions of pith parenchyma placed between source and sink of auxin original polarity lasts in culture, and it is expressed in formation of long vessels composed of cells with well expressed axial features. However, large mass of callus arising from pith parenchyma in the system of the exogenous auxin gradient does not exhibit any axial pattern of growth: division walls are positioned in any orientation to the organ axis and elongational growth is not axial, which leads to the formation of globular nodules of callus. In the tracheary elements differentiated in callus perforation plates are opened, thus they are vessel members. In callus there was no formation of linear vessels, only circular or spiral vessels were formed. The route of vessels formed inside nodules of callus depends on the shape of nodule.

Zróżnicowanie wzrostu tkanek hipokotylu Zinnia elegans L. w odpowiedzi na egzogenną auksynę [Differences in growth of tissues of the hypocotyl of Zinnia elegans L. in answer to the exogenous auxin]
Aleksandra Rusin, Tomasz Rusin, Paweł Kojs, Wiesław Włoch
Exogenous auxin supplied to Zinnia elegans L. hypocotyl segments induces different answer of cells of epidermis and primary cortex, which intensively enlarge, and of cells of vascular system and pith parenchyma, which intensively divide. In outer tissues after application of auxin, the middle lamellas are lysed and cells start to separate. Separation of cells starts with the separation of the tangential walls and then the process occur in the radial walls, the trans verse walls separate at last. In hypocotyl sections cultured in vitro and supplied with exogenous auxin growth of epidermis is almost isotropic, whereas without exogenous auxin growth is mainly transverse.
