一种促进蕙兰种子萌发的西地西菌及其应用
Sildenafil HH6 promotes the germination of Cymbidium faberi seeds and the growth of tissue cultures by lysing phosphorus and secreting IAA, solving the problems of low seed germination rate and slow growth of tissue cultures in existing technologies, thus achieving efficient propagation of wild Cymbidium faberi and protection of endangered orchid species.

AI Technical Summary
Existing technologies are insufficient to effectively promote the germination of Cymbidium seeds and the growth of tissue cultures. Furthermore, the existing mycorrhizal fungi have long cultivation cycles and are difficult to control, making in-situ propagation and conservation of orchid plants challenging.
The Cedecea davisae HH6 strain was used to promote seed germination by phosphate solubilization and IAA secretion, and to enhance plant immunity by upregulating stachyose expression, thereby promoting seed germination and tissue culture growth.
Sildenafil HH6 significantly improves the seed germination rate and tissue culture growth rate of Cymbidium faberi, enabling large-scale propagation of wild Cymbidium faberi and contributing to the in-situ conservation and industrial production of endangered orchid species.
