Effects of concentrations of MS medium, sucrose and polyethylene glycol on bulblet growth of Fritillaria camtschatcensis Ker-Gawl. by a rotary shaker [Japanese]

摘要

The effects of concentrations of MS medium, sucrose and polyethylene glycol(PEG) on bulblet formed on small globular scale of Fritillaria camtschatcensis Ker-Gawl. were researched. The scales were cultured for 4 weeks under continuous light of 1,500 Ix at 25 degreesC on a rotary shaker. Our results show that the standard strength MS medium containing 6% sucrose and 1% PEG provides the optimun condition for inducing and subsequent growing bulblets from scales of Fritillaria camtschatcensis Ker-Gawl.
