The contents of main pigments of photosynthetic apparatus (chlorophyll a, b and carotinoid) in the leaves of Asiatic hybrids varieties during different stage of vegetation was first determined In conditions of northern forest steppe. It was established that 19 varieties of Asiatic hybrids had maximum level of accumulation of chlorophyll pigments (a and b) during the budding period, 4 – during the flowering period, 2 – during the fructification period; the most important value a/b was proper to 8 varieties in the budding period, 6 – in the fructification period and 11 in the flowering period, the maximum accumulation of carotinoind contained in the budding period that was expressed in the adaptive reaction of plants aimed to increase of photosynthetic apparatus resistance during the most dry season period. Analyses of photosynthetic pigment contents in the leaves of Asiatic hybrids varieties showed that the flowing changes in the contents of pigment complex may be considered as indicators of a mechanism of adaptation of lily varieties to the complex of climatic and natural conditions of northern forest steppe of West Siberia.
