Abstract

Impact of the snow disaster occurred in 2008 in South China to the clump bamboo in South Sichuan.

Abstract

The impact of snow disaster in January 2008 was investigated on 51 native and introduced clump bamboo species in a Bamboo Garden of Changning county, Sichuan Province, China. The results indicated that the average frozen degree of the 51 species was 3.2, and among them 14 species were died, and only 3 species (Bambusa multiplex cv. Alphonse, Shibataea chinensis and Bambusa chungii) were not affected. A total of 11 species from 5 out of 15 genus, which were Argesia, Cephalostachyum, Thyrsostachys, Cephalostachyum and Gigantochloa, respectively, were died out of freezing. The rank of frozen degree of 10 other genera was: Schizostachyum > Oxytenanthera > Dendrocalamus > Pleioblastus > Bambusa = Dendrocalamopsa > Indocalamus > Acidosasa > Neosinocalamus > Shibataea. The frozen degrees were lightest on native bamboo species and species introduced from Nanchang, followed by those from Hangzhou, Nanjing. Species introduced from Nanning were frozen, middle extent, and the most serious frozen species were that from tropic area (Xishuanbanna), whose the mortality were up to 78%. The results showed the frozen degree was related with the origins. The more similar the climates were to the origins, the lighter damage the clump bamboo suffered of species from Menglen vivarium of tropic region suffered the most serious damage. The results suggested that the introduction of clump bamboo species should be based on the similarity of the climate, and bamboo species introduced in the south should pass the low temperature test before large scale demonstration.
