Opis:
Experiments on somatic embryogenesis in selected spruce, fir and larch species were performed to determine if this method of micropropagation enables production of quality seedlings for forest nurseries. High frequencies of embryogenic callus in spruce (23-31%) and fir (29%) were achieved when mature zygotic embryos were used as explants, while in larches (36%) only when megagametophytes (endosperms with immature embryos) were used. The possibility of somatic embryogenesis initiation also from somatic embryos (resulting in secondary and third generation of embryogenic callus) indicate high efficiency of this method of micropropagation. The best results at all stages of somatic embryogenesis (good proliferation of embryogenic callus, high rate of embryo regeneration and their survival) were obtained for Norway spruce, European larch and some hybrid larches.

Opis:
The paper presents the descriptions as well as drawings of three species of eriophyid mites found on coniferous plants as new in Poland: Trisetacus juniperinus (Nalepa) from Juniperus procumbens, Eriophyes junipereti Keifer from Juniperus communis L. ‘Hibernica’ and Cecidophyopsis psilaspis (Nalepa) from Taxus baccata L. Additionally, eriophyoid mites collected from Thuja occidentalis and Tsuga canadensis are discussed in this paper.
Na podstawie obserwacji prowadzonych w latach 1998-1999 dokonano przeglądu szpecieli występujących na roślinach iglastych z rodzaju Juniperns, Taxus, Thuja i Tsuga. Dla wykrytych po raz pierwszy w Polsce trzech gatunków szpecieli: Trisetacus juniperinus (Nalepa) na Juniperus chinensis ssp. procumbens, Eriophyes junipereti Keifer na Juniperus communis ‘Hibernica’ oraz Cecidophyopsis psilaspis (Nalepa) na Taxus baccata, wykonano pomiary i rysunki. Potwierdzono także występowanie dwóch gatunków szpecieli: Trisetacus cupressi (Keifer) na Thuja occidentalis ‘Bodneri’ i Nalepella tsugae Keifer, 1951 na Tsuga canadensis.

Opis:
Hericium flagellum (Scop.) Pers. is considered a rare, wood-decaying fungus that occurs on coniferous trees, predominantly on silver fir (Abies alba). In this paper, a new locality of H. flagellum in Wielkopolska Voivodship is presented, along with the macro- and micromorphological features of the collected specimens. Basidiomata of H. flagellum were found in November 2016 and 2017 in the “Olbina” nature reserve (ATPOL Dc-97, Kalisz Forest District), located in a continental mixed coniferous forest close to the northern border of the natural range of silver fir. In 2016, H. flagellum was found growing in the hollow of an old stump of silver fir, and in the following year, this fungus was recorded on a fallen log of silver fir. The implications for conservation are briefly presented. Prospects of further development of the basidiomata of H. flagellum in the “Olbina” reserve are also discussed.

Opis:
Thirty-three type A strains of G. abietina from diseased shoots or needles of P. sylvestris, P. nigra and P. armandii and three strains of Brunchorstia pinea var. cembrae from P. mugo were isolated from four regions of Poland differing with respect to climatic conditions. Genetic polymorphism of the mitochondrial small subunit rRNA (mtSSU rRNA), ribosomal RNA fragment including ITS1, 5.8S and ITS2 and glyceraldehyde phosphate dehydrogenase (GPD) gene was examined by the PCR-RFLP method. Genetic distance was ascertained with respect to B. pinea var. cembrae strains from G. abietina isolated from the examinedpine species (average Nei coefficient 0.137). The smallest genetic distance occurred between the strain groups of G. abietina isolated from P. nigra and P. armandii (0.059) and P. nigra and P. sylvestris (0.061), whereas the highest occurred between the groups of strains deriving from P. armandii and P. sylvestris (0.096). The impact of geographic distance on genetic distance between groups of strains from individual regions has been shown. G. abietina strains originating from mountainous areas were more distanced genetically (on average 0.031) from populations from other regions (Nei genetic distance 0.023). The main factors influencing genetic differences of the pathogen were specificity with respect to the species of the host plant and climate conditions, whereas geographic distance had lesser significance.

Opis:
Picea abies (L.) Karst is one of the most important coniferous species of Europe from both ecological and economical points of view. Traditional methods for the gene pool conservation and biodiversity maintenance in forest ecosystems have been practiced in many countries. For progress in this field using highly polymorphic genetic molecular markers is needed. Our goal was to demonstrate the utility of two polymorphic mitochondrial markers mt15-D02 and nad1 b/c in identification native Norway spruce stands. This molecular markers were tested in 1401 individuals from 59 Polish Norway spruce populations. We detected three alleles, which are called1, 2 and3, for locus mt15-D02 and two alleles , which are called1 and2, for locus nad1 b/c in our material. All five variants of alleles indicate the natural origin of P. abies. Result of this study shows that molecular marker mt15-D02 is easy to use and more informative in compare to marker nad1 b/c.

Opis:
The seeds of forest trees usually transfer numerous fungi species, including pathogens, facultative parasites and saprotrophs. The aim of the present work was to determine qualitative and quantitative composition of fungi inhabiting the seeds of 10 trees species i.e.: birch (Betula pendula Roth.), beech (Fagus sylvatica L.), red oak (Quercus rubra L.), common oak (Quercus robur L.), sycamore maple (Acer pseudoplatanus L.), black alder (Alnus glutinosa Gaerth.), fir (Abies alba Mill.), European larch (Larix decidua Mill.), pine (Pinus sylvestris L.) and spruce (Picea abies (L.) H. Karst). The seed samples were obtained courtesy of 5 forest districts located in the south−eastern Poland. Mycological analysis was performed in the years 2012−2013. Each time, the study included 100 surface−disinfected seeds of particular plant species. As a result of the study about 2000 colonies of fungi representing 26 genera and above 39 species were isolated. The most frequently occurring species were: Fusarium spp., Penicillium spp., Alternaria alternata, Cladosporium cladosporioides, Trichoderma koningii, Epicoccum nigrum, Phoma spp. and Cylindrocarpon destructans. Moreover Discula spp., Phyllosticta spp., Pyrenochaeta spp., Rhizoctonia solani, Alternaria consortiale were obtained only from the seeds of deciduous trees while Truncatella angustata and Sphareopsis sapinea exclusively from the seeds of coniferous trees. The genus Fusarium was represented by 8 species and among them F. avenaceum, F. oxysporum and F. sporotrichioides dominated. Moreover Penicillium spp., Epicoccum nigrum, Trichoderma koningii, Botrytis cinerea, Cladosporium cladosporioides, Chaetomium globosum and Trichothecium roseum were commonly isolated while the other species of fungi were present in smaller numbers. Isolation of numerous fungi species which may cause mold of sowing material, seedling blight as well as leaves and needles spot, indicates their big threat for seeds during storage and for plants in the initial period of growth in a nursery. The obtained results show that the seeds, besides the infected soil, are a very important source of infection for young plants.
