In vitro tuberization of the common potato (Solanum tuberosum) is not a response to the osmotic concentration of the medium

摘要

It has been speculated that the rapid tuberization of explanted etiolated stolon nodes of the common potato relates to the osmotic concentration of the medium since this response is speeded by increased sucrose levels up to 12. This paper demonstrates that the response probably pertains to the energy requirements of the tuberizing explanted stolon and that osmotic concentration is not crucial.
