The Effects of Using Trehalose as a Carbon Source on the Proliferation of Phalaenopsis and Doritaenopsis Protocorm-Like-Bodies

Abstract

In this communication, the effects of trehalose and culture system on protocorm-like body (PLB) growth were investigated. PLB derived from Phalaenopsis and Doritaenopsis cultivars, which were grown on solidified trehalose amended NP medium showed higher proliferation rate than on NP medium containing sucrose. For P. ‘Hwa Feng Red Jewel’ and Dtp. ‘Mount Beauty×Su’s Red Lip’, the proliferation rates on solidified trehalose media were almost two times higher than those on sucrose media after 8-week culture. However, Knudson C (KC) medium did not reveal the similar results between trehalose and sucrose. In liquid culture system, both trehalose amended NP and KC media brought about better results than sucrose containing media for PLB proliferation. For culture system test, solidified media showed higher proliferation rate than liquid media under the same medium composition. Roller bottles were more suitable than flask-shaking cultures in liquid systems for PLB proliferation.
