A comparative study was made of the germination and phenological phases of the development of 1 widespread (Tulipa polychroma) and 3 rare tulip species (T. florenskyi, T. julia and T. eichleri). The plants were exposed to gamma irradiation and chemical mutagens. The epigeal growth of tulips was observed (onset of sprouting, budding, and flowering). Rare tulip species were found to be more sensitive to chemical mutagens (nitrosomethylurea) than the widespread species.
