Abstract

Purpose. The aim of these studies was to determine the effect of the photoperiod, temperature regimes and light intensity on potato tuber formation in vitro. Methods. In experiment № 1, Kobza potato plants were grown in vitro at temperatures of 14–16; 20–22; 24–26°С and lighting 500; 1500; 2000; 3000 lux. In experiment № 2 temperature regime of cultivation day/night 20–22/10–12; 16–18; 20–22°С was studied against the background of photoperiods: recommended by the Institute of potato, ten- and sixteen-hour. Variety Nezabudka was used in the experiment. Results. According to the analysis of variance of the research results, on average over 3 years, the greatest influence on the mass of microbulbs in experiment 1 was the temperature regime (81 %), much less – lighting (15 %). The maximum weight of the average microbulb of the Nezabudka variety was obtained at a day/night temperature of 20–22/10–12°С, regardless of the duration of the photoperiod. Conclusions. The decisive factor influencing the in vitro productivity of the early-ripening Kobza variety is the temperature conditions of cultivation, the light intensity is much less affected. The maximum indicators of plant productivity in vitro were obtained using a temperature of 14–16°С and illumination of 3000 lux. The number of microbulbs per plant was 1.2, the weight of the average microbulb – 262.0 mg, the mass of microbulbs per plant - 363.7 mg, the number of microbulbs weighing more than 350.0 mg – 20.9 %. Temperature conditions were also a decisive factor in the formation of plant productivity in vitro of Nezabudka potato variety. The maximum indicators of tuber formation and the largest mass of microbulbs on all studied photoperiods were obtained at night temperature 10–12°С: 98.9; 99.5 and 99.3 %; 359.3; 356.1; 336.1 mg. Therefore, cultivation temperature conditions have a much greater effect on potato productivity in vitro than light intensity and regimes.
