Dynamika przyrostu pędów żylistka szorstkiego (Deutzia scabra Thunb.) w zróżnicowanych warunkach nasłonecznienia [Dynamics of growth shoots of Deutzia scabra Thunb. in different insolation conditions]
Jolanta Jańczyk-Węglarska, Karol Węglarski
The paper concerns the dynamics offshoots growth of Deutzia scabra Thunb. in various insolation conditions. Field investigation were carried out in 1996 in Botanical Garden of Adam Mickiewicz University in Poznań. The length of growing shoots was measured at 7 days intervals. Statistical analysis was done using Statgraphics 2.1 software. Significant differences in shoot length and their growth dynamics were found for various insolation conditions. A quantitative analysis of shoot growth allowed us to show phenological differences for plants particular species growing in various ecological conditions. We postulate that typical phenological observations should be completed with numerical data on organ growth.

Tworzenie kolekcji i aklimatyzacja niektórych taksonów z gromady Gymnospermatophyta w Ogrodzie Roślin Leczniczych Akademii Medycznej w Gdańsku [Creating of collections and acclimation of selected taxa of division Gymnospermatophyta in Medicinal Plant Garden of the Medical University of Gdańsk]
Wojciech Cisowski, Maria Zielińska-Stasiak, Jolanta Zarębska
This paper presents those species of the Gymnospermatophyta division which are cultivated in the Medicinal Plant Garden at the Medical University of Gdańsk. Some of them (14 taxa) including Abies concolor, Picea pungens have been cultivated since the foundation of the Garden in 1948. Another 57 species were introduced in 1992, when an arboretum was established in the Medicinal Plant Garden. This paper presents the observations of the development of these species in the climate of the Baltic coastal area (The Medicinal Plant Garden is located 2.5 km away from the seashore). This paper documents the acclimation of these species in the Medicinal Plant Garden. Work related to these species pertains to use these plants in health protection not only through direct medicinal application, but also through their use in environmental protection. The plants which show best development include Cryptomeria japonica, Cupressocyparis × leylandii, Pinus armandii, Pinus nigra, Pinus ponderosa, Pseudotsuga menziesii, Sequoiadendron giganteum and Thuja plicata. Some of the above species could be used for large scale planting in city green areas and in household gardens; they would serve to protect from air pollutions and in favourable conditions could assimilate carbon dioxide and produce oxygen the whole year round.

Kolekcja róż Ogrodu Botanicznego Polskiej Akademii Nauk w Warszawie [Collection of roses in the Botanical Garden of the Polish Academy of Sciences in Warsaw]
Marta Joanna Monder
The choice of varieties for the collection is made in such a way to create a rosary showing diversity of Rosa sp. Starting from wild sorts, old garden roses finishing with types grown in recent years. There will be observations of particular varieties conducted which will help to get know them better, to specify their faults, advantages in cultivation, nursing and their decoration value. Sorts were divided into groups taking into consideration many criteria, including aesthetic and project regards. They will be placed in bunches of few or more pieces in irregular colourful spots. The main goal of the collection is enabling visitors getting to know actual varieties and helping to make a right choice of them. On 1900 m2 there are gathered so far 65 varieties of the hybrid roses, 61 of polyanthas and floribundas, 38 of ground cover roses, 41 of ramblers and climbers, 11 of English roses, 21 of shrub, 10 of miniature roses and 22 of wild roses. Among cultivated sorts there are 34 varieties of historical roses: bourbons, centifolias, varieties of Rosa foetida Herrm., Albans, Damasks, Portland’s, Gallicas, hybrid perpetuals.

Bugenwilla – kolorowe pnącze w kolekcji Ogrodu Botanicznego Polskiej Akademii Nauk [Bougainvillea as a colourful climbing plant in the Botanical Garden of Polish Academy of Sciences]
Katarzyna Goller
Genus Bougainvillea includes 18 species but only 3 are of horticultural value. There are B.glabra Choisy, B. spectabilis Willd., B. peruviana Humb. et Bonpl. and a natural hybrid B. x buttiana Holt. et Standley. During the period of 225 years of domestication of this plants more than 300 cultivars have been evolved. In the Botanical Garden there is the biggest and most prominent collection of bougainvilleas in Poland. Collection consists of 4 species and 32 varieties. Plants grow in the greenhouse directly in the ground on pergolas and in pots. Among this group of plants we have very attractive bicoloured cultivar ‘Mary Palmer’ (B. peruviana) and unique cultivar ‘Thimma’ having conspicuously variegated foliage with yellow and green patches and bicoloured bracts. In greenhouse grow also very interesting group of cultivars, known as ‘Million Dollar’ or multibracted bougainvilleas. The more attractive are bugenvilleas hybrid B. × butiana. ‘Mahara’ with rhodamine purple multibracts, ‘Roseville’s Delight’ with orange multibracts and ‘Cherry Blossom’ with white multibracts suffused with mallow purple.

Modyfikacje metody wykreślania diagramów fenologicznych drzew rosnących w warunkach miejskich w oparciu o obserwacje Aesculus hippocastanum L. na terenie Poznania [Modification of phenological diagrams plotting of trees growing under urban conditions based on observation of Aesculus hippocastanum L. in the area of Poznań]
Szymon Łukasiewicz
Plotting phenological diagrams under changed conditions for plants requires their modifications. This often results from extremely unfavourable conditions for development of plants which cause occurrence of necroses of leaf blades already at the end of May. Under such circumstances the autumn discoloration of leaves appeared to a specific percent of assimilation apparatus only. Also in the generative phase the accelerated dropping of fruit before their ripening makes the diagrams less legible. Therefore small modifications have been proposed to make the graphic presentation of phenological phenomena more legible. Achieved modifications make possible presentation of disturbed plant development in transformed environment. Instead of phases following one after another occurred simultaneous duration of several phases with the predominance of the stage of dying.

Polskie kolekcje roślin chronionych i zagrożonych oraz endemitów i reliktów. Część 1. Gatunki objęte ochroną prawną [The Polish collections of protected, endangered, endemic and relict plants. Part 1. Species legally protected by law]
Halina Galera, Jerzy Puchalski, Wiesław Gawryś
This paper summarizes the results of the enquiry delivered among 16 Polish botanical gardens. In these gardens 177 plant species are grown, it means 76% of the total number of 232 species protected legally by law in Poland. Among them 168 taxa originated from natural habitats and were cultivated at least in one garden. In comparison to the similar enquiry recorded in the years 1991–1992 the Polish collection of protected plants were enriched for 11 species.

Ogród kaktusowy na Lanzarote (Wyspy Kanaryjskie) [The Cactus Garden on Lanzarote (Canary Islands)]
Tadeusz Baranowski, Ewa G. Dankowska
The Cactus Garden was the most recent of the Lanzarote Island Councir’s Tourist Centres to open. Built in circular shape in the form of an amphitheatre, the garden is surrounded by walls of thick volcanic rock. The beds housing the cacti are covered with Layers of the black porous volcanic grains, known as lapilli. one sees on fields throughout the island. More them 1400 species of cacti and succulents can be seen in the grounds and the surrounding terraces.

Kolekcje grzybieni (Nymphaea) – propozycje wyboru gatunków i odmian do ekspozycji ogrodowej [Water-lily (Nymphaea) collections – suggestions of choosing species and varieties for garden display]
Ryszard Kamiński
The botanical gardens are situated mostly close to the centres of town agglomerations. Usually they do not possess water surface large enough (one larger pool or more smaller ones) to grow a great amount of typical water plants with submersed or floating leaves. In such a situation there is also difficult to expose diversity and beauty of bigger groups of very attractive plants standing taxonomically close which is the case with hardy water-lilies. Apart of species and natural varieties which can be grown in our climate (a dozen or so), there are more than 200 garden cultivars of Nymphaea, differing often only in details; they have been obtained by gardeners during many years of hybridising and selection. Nevertheless, about 30 taxa will be enough to show full diversity of these plants and probable any botanical garden is able to ensure them a proper water surface.
