Regulation of Potato Morphogenetic Processes in vitro by Hormonal and Light Actions

Abstract

The research on how phytohormones and light affect the morphogenetic responses of potatoes in culture conditions is presented in this article. Researchers looked at how growth promoters affect the regulation of potato morphogenesis in in vitro cultures of different potato varieties. They also looked at how light quality affects this regulation. Research has been conducted on Kazakh selection potatoes, which are commonly grown in Northern and Central Kazakhstan. In the course of the research, various variants of phytohormones and light quality were used for the growing and developing of micro-gears in vitro. The light quality has a different action on the potatoes' speed of growth. For example, rhizogenesis for the Tamyr variety has increased because of red light use. For the Aksor, Orbitaa, and Nerli varieties the best results were got in case the white light has been used. The concentration of the phytohormones has an influence on the potatoes growing. So, the most effective leafiness of shoots of all considered potato varieties has been gotten by auxin use in the concentration of 0.1 and 0.5 μM.
