Tuberization and abscisic acid content inSolanum tuberosum as affected by nitrogen nutrition

  title={Tuberization and abscisic acid content inSolanum tuberosum as affected by nitrogen nutrition},
  author={Alexander Krauss},
  journal={Potato Research},
Potato plants (Solanum tuberosum L.) were grown under constant climatic conditions in water culture with continuous and discontinuous nitrogen supply. The effect of N nutrition on tuberization and abscicic acid (ABA) content in various parts of the plants was investigated. With the exception of the stolons, interrupting the N supply caused an increase in the ABA content. After renewed N supply the ABA content dropped within 3 days to the original level. With continuous N supply the ABA content… CONTINUE READING
