Investigation on Germplasm Resources of Shoot-producing Bamboo Species in Guangxi and Their Utilization
The germplasm resources of bamboo species for producing shoots and their utilization in Guangxi are investigated.The results show that there are 41 species(including varieties or cultivar)in 6 genera suitable for bamboo shoot producing in Guangxi.Among them,there are 24 species in 3 genera that have bamboo shoots emerge in summer,while Dendrocalamus latiflorus,a large-sized sympodial bamboo species,is largely planted and D.brandisii show a great development potential.A total of 14 species in 2 genera produce shoots in both winter and spring,among which Phyllostachys edulis,a large-sized monopodial bamboo species,has the largest area of planting,but it is mainly used for producing culms with a low yield of shoots,and other bamboo species in Phyllostachys and Indosasa are sporadically planted.Only 3 bamboo species in 1 genus of Chimonobambusa produces shoots in autumn,which is also called"Chongyangsun"but their shoots are rarely utilized.Among the bamboo species used for bamboo shoots,the artificial planting area of D.latiflorus,D.brandisii,D.oldhami,Ph.edulis and Ph.violascens'Prevernalis'exceeds more than 6.67 ha.The investigation also finds some new bamboo species for shoots production,whose shoots are in good quality,but they are in an endangered condition due to small population.Guangxi should pay attention to the utilization of various bamboo species,including not only D.latiflorus,but also D.brandisii,Ph.edulis and Chimonobambusa,so as to build a pattern of yearlong bamboo shoots supply.In addition,more efforts should be taken to increase the cultivation and utilization of excellent and endangered shoot-producing bamboo species in Guangxi,select and breed the bamboo species with improved production of shoots,and accelerate the promotion and planting of the selected species.
