Abstract：The differences in environmental suitability and growth rates between bamboo species artificially cultivated for the giant panda were measured using quadrat plots in the year they were planted. The results showed that the survival rates of all bamboo species were above 84% except for Chimonobambusa neopurpurea, whose survival rate was 60.56%, and the survival rates of Ch. neopurpurea and Phyllostachys bissetii were significantly different (P<0.05). The average number of bamboo shoots per 100 clumps of mother plants for Fargesia robusta, F. angustissima, Ph. bissetii, Ph. nidularia, Ch. szechuanensis var. szechuanensis, Pleioblastus maculatus and Ch. neopurpurea were 320, 277, 231, 181, 165, 61, and 59, respectively. The buds of F. robusta, F. angustissima and Ph. bissetii were dormancy-released and they produced many more bamboo shoots than the others, while the bamboo shoots number of P. maculatus and Ch. neopurpurea were the least. The shoot survival rates of Ph. nidularia, Ph. bissetii and F. robusta were the highest at more than 97%, which were followed by F. angustissima and Ch. neopurpurea, and Ch. szechuanensis var. szechuanensis and P. maculatus the lowest. The average basal diameter of new bamboo was the largest in Ch. szechuanensis var. szechuanensis at 0.858 cm, the second largest in P. maculatus newborn bamboo at 0.662 cm, and the smallest in F. robusta newborn bamboo at 0.265 cm. The differences in the basal diameters of newly born bamboo were significantly different from each other (P<0.05), except for those of Ch. neopurpurea and F. angustissima, Ch. neopurpurea and Ph. nidularia, Ph. nidularia and F. angustissima, and Ph. nidularia and Ph. bissetii. The average culm height of Ch. szechuanensis var. szechuanensis was the highest at 88.4 cm, second highest in P. maculatus at 64.8 cm, and the lowest in F. robusta at 22.0 cm. The growth rate of new culm heights were significantly different from each other (P<0.05) except for Ch. neopurpurea and Ph. nidularia, Ph. nidularia and Ph. bissetii, Ph. nidularia and F. angustissima, Ph. bissetii and F. angustissima, and P. maculatus and Ch. szechuanensis var. szechuanensis. Generally speaking, among the bamboo species planted for the giant panda, Ch. Neopurpurea was the worst in the planting effectiveness and environmental suitability, and then P. maculatus showed better performance than Ch. Neopurpurea, while the other species of bamboo were good in growth performance.
