Mature seeds began to germinate after 12 days of aseptic sowing, and grew into round bulbs about 1 cm in height after 60 days, with 2~3 true leaves, and began to take root. After inoculating round bulbs in domestication medium for 60 days, they were transferred to proliferation medium for culture. After about 60 days, each seedling could form 3~7 lateral buds. In the process of proliferation culture, with the increase of subculture times, the ability of seedlings to form lateral buds increased and the number increased. Normal seedlings with a height of about 2 cm in the propagation seedling culture medium were inoculated on the seedling culture medium for culture. After 60 days, the seedlings are about 4 cm high, Ye Zhan, light green, thick stems and developed roots. At this time, because the pseudobulb is tender and the root system is long, the survival rate of transplanting out of the bottle is low. After cutting off the long root system of healthy seedlings properly, it is transferred to the strong seedling culture medium for culture. After 13 days, new roots will grow again. After 30 days, the leaves of the seedlings turned pale yellow-green, the toughness of pseudobulb increased, and the root system was developed, with a length of 1~2 cm, which was white or light green with a large number of white root hairs. Transplanting can be carried out at this time. It takes 9~ 10 months for the seeds of Dendrobium nobile to be cultivated from sowing to seedling hardening.
Dendrobium nobile can bear fruit about 1 year. The seed maturity is11~ February of the following year. Immature seeds are white and mature seeds are yellowish. It is usually harvested and sown before the peel turns yellow and is not listed.
