Division of Floriculture

Head - Prof. Dr. M. Grzesik

Floriculture Division was established in 1969 as a branch of the Research Institute of Pomology in Skierniewice. It employs 36 research workers and 12 technicians.


There are the following departments in the Division of Floriculture

  • Department of Nursery and Seed Production of Ornamental Plants
  • Department of Cultivation of Ornamental Plants
  • Department of Protection of Ornamental Plants
  • Department of Biotechnology
  • Department of Physiology and Morphogenesis of Ornamental Plants

  Department of Plant Breeding conducts research on breeding and varietal evaluation of tulip, lily, gladiolus, daffodil and streptocarpus; conventional and mutational breeding of alstroemeria; development of mass regeneration methods for some cut flowers and potted plants, the use of in vitro cultures for mutational breeding, Agrobacterium-mediated transformation of plants.

    The research work of Outdoor Plant Section is concentrated on vegetative and generative propagation, container culture and clonal selection of ornamental trees, shrubs and perennials. Great attention is also paid to the improvement of cultivation methods in greenhouses. It includes the use of rockwool in carnation and potted plant cultures, elaboration of fertilization programs, acclimatization of in vitro propagated plants, CO2 enrichment and assimilation lighting, the effect of growth regulators on growth and flowering of cut flowers and potted plants, evaluation of different methods of pruning and cutting of roses, evaluation of rose cultivars with special regard to the resistance to fungal diseases.

        In the Department of Plant Protection research is made on new diseases occuring in Poland, biological and chemical control of soil-borne pathogens, chemical control of powdery mildew and black spot on roses, chemical control of Botrytis blight and Fusarium rot on bulbous plants, epidemiology of downy mildew on Goniolimon and its chemical control, pathogenic fungi transmitted by seeds, evaluation of new herbicides development of feasible programs of protection against pests of plants cultivated outdoor and under covers, effectiveness of new acaricides and insecticides; occurrence, harmfulness and control of pests and plants cultivated outdoor and in greenhouses. Work on virus diseases is focused on methods of purification and early detection of tomato spotted wilt virus, occurrence and pathogenicity of virus on Freesia, Lilium, Hippeastrum, Dianthus, Gerbera, Lilium, Hippeastrum, Dianthus, Gerbera, orchids and potted plants. Laboratory of Tissue Cultures is actually working on micropropagation of Lillium, Limonium, Goniolimon, Paeonia, Ficus benjamina, development of direct rooting of microcuttings; role of growth regulators, light quality and other factors in growth, development and acclimatization of plantlets: somatic embryogenesis.

    In Floriculture Division research is also directed toward improvement of seed production and seed storage methods. The effect of agrotechnical factors, architecture of plants, maturity, growth regulators on seed quality is examined. Postharvest research is concentrated on prolongation of vase-life of cut flowers, cold storage and transportation of cut flowers and potted plants; the effect of different light quality on ethylene biosynthesis, rooting of cuttings, growth, development and quality of potted plants.

    In Laboratory of Plant Physiology research on hormonal control of growth and development of ornamental bulbous plants is conducted. The following topics are investigated: the role of exogenous growth regulators, hormones, mechanical wounding and methyl jasmonate in growth and development control of bulbous plants.
