Dendrobium nobile, also known as Millennium Run? , a perennial epiphytic herb of Orchidaceae, is called "Dendrobium nobile" because its stems are small at both ends, thick in the middle, flat and golden in color. Dendrobium nobile was regarded as a sacred product of nourishing yin by doctors in past dynasties, and Taoism was regarded as the first of the nine immortals. The seeds of Dendrobium nobile can germinate under artificial conditions. The seeds of Dendrobium nobile are tiny and powdery, with a length of 0.75~ 1. 10 mm and a width of 0.09~0.20 mm Its structure can only be seen clearly under a light mirror. Under wild conditions, it can germinate only when it grows with other bacteria, and the flora provides the nutrients needed for germination, so the germination rate is extremely low. Under artificial conditions, given rich nutrients and suitable light, temperature and water and humidity conditions, normal germination can be achieved.

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.
