The artificial breeding of plant light leaf ferns for protection at the national level has been successful

Xinhua News Agency, Chengdu, July 22 (Reporter Zhang Hailei) State-level protection plant light leaf in 1963 was first found in Tian county, Sichuan, yilangshan group cattle Ping. At present, the number of less than 100 plants, are wild plants. Reporters from the Sichuan Provincial Forestry and Prairie Bureau was informed that, after many years of exploration, recently researchers rely on its bead buds to successfully achieve artificial breeding of light-leaf ferns.
, some institutions carried out spore reproduction research, but only to the stage of the lithosome, did not really seedling. This puts the total area of the species less than 20 square meters, the total number of less than 100 plants of light leaf ferns at any time at risk of extinction.
It is understood that the "Chinese Botany" describes the genus of light-leaf ferns "in the classification position between the hoof cover genus and the cold genus, the difference is that the bottom side of the feather shaft in the middle of the feather has a small protrusion of an unknown nature." In 2012, the State Forestry Department launched the Second National Survey on the Protection of Wild Plant Resources, and the light leaf ferns were included in the main species. Associate Professor Chen Xiaohong and his team from Sichuan Agricultural University participated in the survey.
Since 2015, Associate Professor Chen Xiaohong and his team have been observing light leaf ferns continuously in the wild, in 2016, artificial breeding experiments have been carried out on photo-leaf ferns, and in 2018, the team has completed a preliminary study of the endangered mechanism of light-leaf ferns, and determined that "small protrusions of unknown nature" are bead buds, which mature and fall into the soil and can grow into new plants. By July 2020, the research team had not only repeatedly proved the theory about the reproduction of photo-leaf bead buds, but also found the technical requirements for artificial breeding at various stages through controlled experiments, and obtained plants through artificial cultivation, initially establishing an artificial population of photo-leaf ferns.
