The parameters of chlorophyll a fluorescence induction were measured: Fv/Fm, Sc/Fm, Rfd and coefficient of Ld delayed luminescence decay kinetics, related with a course of primary photosynthesis reactions on leaves of strawberry plants, cultured in vitro by means of the micropropagation methods. Strawberry plants cv. Ananasowa from in vitro cultures in optimal condition show significantly higher values of luminescence parameters indicating better condition of plants of this variety in comparison with the variety Senga Sengana. After temperature lowering, however, these values were more reduced than for plants of Senga Sengana, which can be interpreted as higher susceptibility of this variety to chill. Addition of BAP caused disturbance of primary photosynthesis reactions rate, particularly in lower temperature. Auxin 2,4-D had no effect on the luminescence parameters in comparison with control cultures. Dehydration stress strongly diminished the values of measured parameters for Ananasowa variety what indicates the inhibition of primary photosynthesis reaction in leaves. The old culture of Senga Sengana variety showed higher tolerance on linuron in comparison with the new one.
