    Collection of Experiences: 25 Years’ Work on Seed Propagation of Allochthonous Woody Plants in Skopje and Their Possible Role in the Urban Landscape
    (SEEFOR, 2023-06-28)
    ;
    ;
    In the past decades, numerous landscaping efforts in the urban and suburban areas of Skopje have provided a diversified presence of allochthonous woody species. From the registered 206 allochthonous woody plants, in the past 25 years, 65 species (19 Gymnospermae and 46 Angiospermae) have been the focus of various research and monitoring efforts, including seed propagation and analysis of the generative propagation potential. Considering the variability in the experimental approach, we have performed an extensive literature revision and combined the results from the two in a summary of species that could be of potential interest in the green infrastructure in Skopje, due to their benefits (ornamental use and air pollution remediation) or risks (invasive and allergenic potential). We have also underlined the potential of using urban species as seed banks and species conservation, along with various services they could provide. To the best of our knowledge, this is the first attempt that summarizes the allochthonous woody species in Skopje along with the experience regarding their generative potential and possible use in urban forestry. As such, it serves as a base for future experimental research that could provide more information about the seed quality and the species’ benefits in Skopje and the surrounding areas.

    Collection of experiences from 25 years work on seed propagation of allochthonous dendroflora at the Hans Em Faculty of Forest Sciences, Landscape Architecture and Environmental Engineering in Skopje and the surrpoundings

    Various efforts in the past decades have contributed for a large variety of allochthonous tree species to become a part of the urban and suburban landscape in Skopje. Of more than 200 registered allochthonous species in the urban and suburban green areas of the city of Skopje, we propagated from seed 65 species, of which 19 coniferous and 46 broadleaved, and subsequently analysed the attributes of their generative propagation potential. This paper summarizes 25 years’ experience in generative propagation of allochthonous species at the „Hans Em“ Faculty of Forest Sciences, Landscape Architecture and Environmental Engineering (HEF) in Skopje, R. of North Macedonia. The collected cones, fruits or seeds were processed to obtain sawing reproductive material. According to the quantity of the collected material and seeds/fruits characteristics, the quality features of the seeds were examined (seed germination rate or viability, seed purity). Prior sawing, according to species dormancy characteristics, different pre-sowing treatments were performed, e.g., pre-soaking in cold water; hydro-thermal procedure; pre-soaking in warm water; maceration in hydrogen chloride; and seed cold stratification. The seeds were sawn in the nurseries of the HEF and in some nurseries of the PE National forests, in containers or in soil. Selection of the nurseries for the seedling production was made in terms with the ecological conditions, favourable for the certain species. One-year old seedling were measured for the shoot height (SH) and root collar diameter (RCD). Seeds germination/viability rate varies in wide range. Seedlings features also vary, depending mostly on nursery technology (bare root and container seedlings) and skills of the nursery stuff. Largest differences in seedlings SH and RDC were recorded within the broadleaved bare root seedlings (e.g. in black locust up to 1000%), while in coniferous species the differences were not of such high significance. Generally, one-year old coniferous seedlings achieved better results in containers, while seedlings of broadleaved species in soil. These results, achieved during two-and-half decades, demonstrate that urban and suburban green areas in the city of Skopje can provide reproductive material for nursery production of species both for ornamental and reforestation purpose. Thus, further optimization as well as research regarding most suitable techniques for generative propagation is needed.
