Mark Bridgen

My primary research interests are in the areas of new plant development and breeding, plant environment interactions, plant cell and tissue culture, in vitro plant breeding, genetic modifications for plant improvement, plant propagation, and plant growth and development of floricultural and ornamental plants. Specific in vitro breeding techniques include somaclonal and gametoclonal variation, embryo culture, somatic embryogenesis, mutation breeding, meristem culture for the production of pathogen free plants and in vitro fertilization. Specific applied studies focus on herbaceous ornamental plants, field-grown cut flower production, use of high tunnels for season extension, plant propagation, greenhouse crop production, and cultivar evaluations. Since coming to Cornell, I've developed and patented two ornamental Alstroemeria cultivars: 'Tangerine Tango' (2012) and 'Mauve Majesty' (2007).

Plant propagation, the multiplication of plants, is both a science and an art. This class introduces the principles, practices and techniques of sexual and asexual propagation of horticultural plants. The science of plant propagation is taught by explaining plant physiology, cultural practices and characteristics of plants. The art of plant propagation is learned by completing laboratory exercises. Seed propagation, cutting propagation, grafting & budding systems, layering, specialized plant structures (bulbs, corms, etc.), and tissue culture for micropropagation are discussed and practiced.
