- Abstract
Five genotypes of potato (Solanum tuberosum L.) were induced to form microtubers under two in vitro culture conditions (continuos darkness and light). Cultures maintained under continuos darkness (with a temperatue of 17°C) had a higher yield with a greater number of microtuber (1.394/plantlet) than those maintained under long days (16 h of light/day) combined with temperature of 20°C. In the last case the microtubers were higher, with with the highest average weight of 0.602 g. Three phytohormones it was used: coumarine, benzylaminopurine and salicylic acid. Regarding the average number of microtubers obtained when it was used coumarine and salicylic acid, the highest average number of microtubers was recorded (1,135 microtubers/plantlet). The study had been performed also on two fractions of the of sugar quantity (80 and 140 g/l), but they had less influence compared to the varieties.
