Abstract
Possibility of differentiation of two Siberian larch species (Larix sibirica and L. gmelinii) at species and . population levels using long-living cell cultures in vitro was studied. For the first time interspecific and intraspecific differences in proliferative activity of calluses were found in Siberian larch species on a medium with sodium fluoride were found. A conclusion was made that larch callus culture can be used effectively for the studies of inter-and intraspecific polymorphism in larch with respect to sensitivity to fluorine and other technogenous pollutants when studying possible genetic consequences of action of industrial emissions on cell genome of larch.
