PROCESS FOR PRODUCING TUBER.

摘要

A process for producing tubers of a solanum readily in a large amount, wherein the stolon and foliage which have grown in a liquid phase under application of carbon dioxide in the light period of the foliage growth stage are exposed to a gas phase in the tuber formation stage to form tubers in a high yield, and the culture in the tuber formation stage is conducted while aerating the gas phase of a culture tank to form a large amount of tubers not only near the boundary of the culture medium but also in the gas phase apart from the medium. As a result, the efficiency of tuber formation and the quality of the tuber are improved.
