Two new species of bamboo species are located in the wildlife species resource bank in southwest China

recently, the seed family of the wildlife seed bank in southwestern China welcomed two special new members, Yushania and Ampelocalamus, to collect seeds in the wild. Of the tens of thousands of plant seeds collected by the seed pool over the past ten years, these seeds have special significance.
China is the world's most abundant bamboo resources, in the type of bamboo, distribution area, accumulation, bamboo and bamboo shoot production and other aspects of the world's first. Bamboo plants play an important role in Chinese's life and have great economic, ecological and cultural value, however, the seeds of bamboo plants are only a small number of preserved in the southwest wildlife seed resource bank, which is mainly determined by the special breeding methods of bamboo. Bamboo is mainly nutritional reproduction, rarely sexual reproduction, bamboo flowering is considered to be one of the most attractive phenomena in nature, its flowering cycle from 3 to 120 years, most of the woody bamboo species are one-time flowering, flowering after death, so it is difficult to encounter bamboo flowering. Bamboo strong rare and precious can also be seen from the ancient saying "Phoenix non-yu, non-practice not to eat, non-spring do not drink", which refers to the seeds of bamboo, also known as bamboo rice. The above causes make it difficult to collect bamboo seeds.
March 2020, the Kunming Plant Research Institute Li De baht bamboo research team cultivated in the greenhouse of the suspended bamboo genus Ampelocalamus Luodianensis ushered in flowering, the species was introduced in 2010 from the southwestern Province of Guizhou Province, the Bui Hmong Autonomous Prefecture Luodian County; In May of the same year, Dr. Cai Jie of the Collection Department learned from a circle of friends that bamboo was blooming in the Wumun Prairie of Guizhou Province with six pans of water, and then the bamboo research team carried out a field survey and found yushania mabianensis, a bamboo genus of Yushania Mabianensis. Suspended bamboo genus mainly grows on limestone topography and is rattan-like, while Yushan bamboo genus is alpine bamboo, and some bamboo species are important food sources for giant pandas. Based on the flowering period and experience, the staff of the seed bank collection department and the bamboo research team then formed a joint collection team to go to the Umun Prairie and Luodian County in September to collect seeds. Field investigation found that the bamboo genus Yushan in the Umun Prairie has been a large area of dead, only sporadic parts are still flowering, through careful search, a total of more than 2000 full seeds collected. While collecting small canopy bamboo seeds in Luodian County, it was found that the population is mostly in the early stages of flowering, some of the seeds have matured, a small number of bamboo clumps dried up, and a small number of bamboo groves found some real seedlings, researchers estimate that the next 1 to 2 years will enter the flowering period.
present, the batch of seeds has been stored in accordance with the seed bank preservation norms for a long time, followed by related seed germination, seed form and ultra-low temperature preservation research. In view of the difficulty of collecting bamboo seeds, the lack of research materials such as seed storage characteristics and seed preservation techniques, the collection of seeds of other species of bamboo will be further strengthened to ensure that bamboo, a special seed resource, is preserved and used effectively in the long term.
the Southwest China Wildlife Species Resource Bank was proposed by Wu Zhengxuan
, a well-known botanist in China, and became a major national scientific and technological infrastructure in 2008 and was built and put into use. At present, 10285 kinds of important wild plant seeds have been collected and preserved in China, accounting for 35% of the total number of seed plants in China.
