Invertase activity as affected by cytokinin-like compounds during potato tuberizationin vitro

​Factors Affect to Stolon Formation and Tuberization in Potato: A Review

“…Kinetin which is one of the adenine-type of cytokinins can inhibit tuberization when adding to the culture medium, but it induces tuber formation with a 6% or higher concentration of sucrose in in-vitro media. Thidiazuron which belongs to the phenyluron-type of cytokinin and kinetin induce early tuberization, rapid stolon growth and enhance the number of tubers by stimulating basal acid invertase activity (Palmer and Smith, 1970;Pelacho and Mingo-Castel, 1991;Kefi et al, 2000;Aksenova et al, 2009). Another adenine type of cytokinins: 6-benzyl amino purine (BAP) and zeatin riboside promote tuber formation by increasing glycolysis and ATP synthesis activity (Mauk and Langille, 1978;Cheng et al, 2019).…”

Although many plant hormones are assumed to be involved in the regulation of the tuberization, such as those mentioned previously, their effects finally depend on the gibberellin content of tissues (Xu, van Lammeren, Vermeer, & Vreugdenhil, 1998).…”

Evaluating the Effect of Photomixotrophic Conditions for Expedite and Efficient <i>In Vitro</i> Tuberization System on the Morphological, Biochemical, Anatomical and Physiological Characteristics of Microtubers

“…Because of their small size and weight, microtubers have remarkable benefits for getting disease free plant material, easy storage and transportation (Kefi et al, 2000;Kanwal et al, 2006) over conventionally grown seed potatoes. The other benefits are the less chance of drying out while storage, short dormancy time and high rate of survival in direct transfer to soil (Kefi et al, 2000). Therefore different research groups around the globe are trying to bring about this revolution (Gopal et al, 2004;Zhijun et al, 2005;Zhang, 2006).…”
