Phenology of flowering, pollination and fruit set in the dendrobium lineale rolfe

The study aim was to understand development of flowers, pollination mechanism and fruit development of Dendrobium lineale which expected to provide scientific knowledge and useful information for cultivation and plant conservation efforts. The study had used descriptive observational method. The data was obtained from flowering, pollination and fruit forming had analyzed descriptively. Besides, the observation toward environmental factors of flowering phenology, pollination and fruit formation on D. lineale included minimum and maximum temperature, moisture and light intensity. The result found the duration in the flowering process of D. lineale Rolfe (between bud phase and perfect blooming phase lasting before wilting) was 4 months. The longest time required in the D. lineale Rolfe fruit formation (between fertilization phase and fruit growth and development phase) was 3 months. The flowering stages which occurred in D. lineale Rolfe consisted bud phase, flower bud phase, resupination phase, broken bud phase and bloom phase. The successful artificial pollination techniques on D. lineale Rolfe with “selfing” is shown by the formation of the fruit on the plant itself. The morphological changes which occurred during the flowering phase until the fruit formation indicated changes in shape, size and colour of the flowering buds, flower and fruit.
