PROCESS FOR PRODUCING POTATO MICROTUBERS

摘要

A process for producing potato microtubers comprising the first step of conducting the culture in a relatively low sugar-concentration medium under the condition of a relatively high daily dose of optical radiation and the second step of conducting the culture in a relatively high sugar-concentration medium under the condition of a relatively low daily dose of optical radiation, wherein the first-step culture is conducted in the presence of exogenous ethylene, while the second-step culture is conducted in the absence of exogenous ethylene, thus producing numerous microtubers readily in a short period of time.
