1 T-series were the most susceptive varieties in different Oncidium.

2 Oncidium was autotrophic without sugar in the medium.

3 Survey and pathogens identification of viral disease on Oncidium, Phalaenopsis, and Cymbidium hybrid were carried out in Yunnan.

4 Therefore, the mannan metabolic mechanism in current Oncidium pseudobulbs during inflorescence development was studied.

5 Cause of viral disease of Oncidium and Cymbidium is one or two of ORSV or CyMV in Yunnan.

6 Effects of different media and coagulant on the growth of in vitro Oncidium shoots.

7 The result of this study can be served as the useful information to draw the adequate Oncidium production regions according to its local weather conditions.

8 The transformation rate obtained by applying the genetic transformation condition of Phalaenopsis on Oncidium was lower.

9 The results showed that this technology can effectively detect the genetic variation of Oncidium.

10 The relationship between the cut flower quality and growing temperature of Oncidium Golden No. 2 was studied.
