Table 1 Tuberization of the ST mutant under various conditions in vitro

From: Morphological and molecular characterization of a spontaneously tuberizing potato mutant: an insight into the regulatory mechanisms of tuber induction

  Normal shoots Tuber-like swellings Tubers
High irradiance (PPFD 400–500 μmol m-2 s-1)
1% sucrose 93% 7% 0%
2.5% sucrose 88% 12% 0%
3% sucrose 14% 67% 19%
5% sucrose 0% 36% 64%

7% sucrose 8% 38% 54%
  1. Cultures were raised from single-node cuttings. Percentage values are based on 50 and 100 cuttings cultured under low and high irradiance, respectively. Lada cuttings only rarely (< 5% cuttings) formed tubers in the light under any conditions tested in this study.
