In recent years, researchers at the Xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences have focused on restoring wild populations of endangered orchids. By mimicking the natural regeneration process of epiphytic orchids, they have greatly improved the germination rate of their seeds. Such techniques have ensured the survival of endangered species and the preservation of their genetic resources. (CGTN)
Researchers from Xishuangbanna Tropical Botanical Garden (XTBG) used seeds of Papilionanthe teres, a locally endangered and medicinally valuable epiphytic orchid in Xishuangbanna, to attract germination-enhancing fungi on its four host plants. They placed orchid seed packets near the roots of adult P. teres plants to locate, isolate, and identify naturally occurring fungi capable of stimulating seed germination under natural conditions. They also wanted to test the effects of the fungi on seed germination and protocorm development of P. teres.
In a recent study, researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) investigated how fungi isolated from protocorms of the endangered epiphytic orchid, Dendrobium chrysotoxum (an epiphytic orchid species that grows on tree trunks or as a lithophyte on rocks), and three related Dendrobium species affected seed germination and seedling development under in vitro conditions.
