  • Flowers of Oncidium Gower Ramsey ‘Gold No. 2’were observed to identify their developmental stages according to the morphological changes in different parts of a flower. and their changes in morphology,size,duration and weight（ fresh weight and dry weight） at each developmental stage were determined. The flower development of Oncidium Gower Ramsey was divided into eight stages: bud stage,bud burst stage,half-opened stage,pre-blooming stage,blooming stage,initial stage of senescence,senescence stage,and withered and abscised stage. The vase life for flower development from the bud stage to the withered and abscised stage was about 16-9 days,and the duration of optimal vase life（ from the half-opened stage to initial stage of senescence）for viewing was 4-8 days. In the development process of Oncidium Gower Ramsey cut flower,fresh and dry weight of each part of the cut flower tended to increase before and decline after the blooming stage.

Abstract: Flowers of Oncidium Gower Ramsey ‘Gold No. 2’were observed to identify their developmental stages according to the morphological changes in different parts of a flower. and their changes in morphology,size,duration and weight（ fresh weight and dry weight） at each developmental stage were determined. The flower development of Oncidium Gower Ramsey was divided into eight stages: bud stage,bud burst stage,half-opened stage,pre-blooming stage,blooming stage,initial stage of senescence,senescence stage,and withered and abscised stage. The vase life for flower development from the bud stage to the withered and abscised stage was about 16-9 days,and the duration of optimal vase life（ from the half-opened stage to initial stage of senescence）for viewing was 4-8 days. In the development process of Oncidium Gower Ramsey cut flower,fresh and dry weight of each part of the cut flower tended to increase before and decline after the blooming stage.
