Substancias con actividad citoquinínica estimulan la brotación de yemas en tubérculos de papa

Abstract: RESUMENAntes de la formación de brotes el tubérculo de papa sufre un período de dormancia característico de cada genotipo. En condiciones favorables para la tuberización, se interrumpe el crecimiento longitudinal del estolón y se ensancha la región subapical entre los dos últimos nudos de cada estolón. Entre los factores participantes de este proceso es clara la acción coordinada de varios fitorreguladores. La presencia de citoquininas en S. phureja Juz. et Buk. var. Criolla Colombia y en S. tuberosum L. varie… Show more

“…Such control is exercised through some auxin, possibly the 3-indolyl-acetic acid (IAA), synthesized in the apical region and transported to the lateral meristem. Thus, the removal of the apical meristem afforded the increased availability of cytokinins in the lateral meristems (García-Flórez et al, 2009). Cytokinins are also crucial in promoting budding gems in propagative organs (García-Flórez et al, 2009).…”
