Chen points out that the butterfly orchid has long been susceptible to bacterial soft rot. Inter-breeding of various types has never been able to resolve the problem. Presently they are transferring a bacterial-soft-rot-resistant gene that can be found in tobacco, in hopes this will solve the problem.
由於蝴蝶蘭一直有嚴重的軟腐病，過去用雜交育種的方法無法解決，現在選殖的是存在菸草中的抗病基因，希望能解決此一問題。
