Reasearch on Cold Resistance of Some Bamboo Species in Rizhao
Abstract：As main limiting factor, low temperature in winter affects the use and promotion of Bamboo species in the land- scape greening of Chinffs higher latitudes. In order to explore cold resistance mechanism and expand the introduction range, six Bamboo species were used as test materials, lethal temperature 50 (LT50) was calculated with logistic formula through determi- ning electrolyte leakage rate. Influences of cold stress on soluble sugar contents , soluble protein contents and proline contents were investigated. With cold stress increased,electrolyte leakage rate increased, soluble sugar contents , soluble protein con- tents and proline contents decreased after an initial increase. By evaluating comprehensively the mechanism of cold resistance, the cold resistance of 6 bamboo species was evaluated as Phyllostachys aureosulcata cv. Spectabilis 〉 Pseudosasa japonica Phyllostachys aurea Carr. ex A. et C. Riv 〉 Pleioblastus amarus 〉 Indocalarnus longiauritus Hand. -- Mazz 〉 Shibataea chinensis Nakai.
