Dedrobium Lucky Girl leaves position presented different cell membrane thermostability, respectively. It has enhancing the relative injury value when temperature exceeded 50degC. In terms of silicon dioxide treatments decreased leaves ion leakage, malondialdehyde content, and existed higher chlorophyll content which evaluated by water bath temperature at 50degC. Result not only presented higher root activity and chlorophyll SPAD value at 150 mg./L silicon dioxide treatment, but also showed more leaves at 300-600 mg./L silicon dioxide treatments during vegetative stage. Even though, silicon dioxide treatments had no significant difference among some horticultural characteristic, however it decreased flower bud abortion rate at 150 mg./L treatment.
