Abstract:

The survival rate and cold-hardiness physiological indicators such as SOD and soluble protein, have been studied on introduced five bamboo species and local one in Qingdao. The six bamboo species are Phyllostachys aurea，Phyllostachys aureosulcata f. spectabilis， Sasa argenteastriatus，Phyllostachys arcana f.luteosulcata, Phyllostachys nidularia and Phyllostachys arcana. The results are as follows: The survival rate of Phyllostachys aurea, Phyllostachys aureosulcata f. spectabilis, Sasa argenteastriatus ,Phyllostachys arcana f.luteosulcata and Phyllostachys nidularia, which was 94.84%,87.16%,100%,100%and 95.16% respectively. The SOD of Phyllostachys arcana was steady and those of other five bamboo species were negatively correlated to the temperature. The soluble protein content of six bamboo species increased gradually with decreased temperature.
