Sampling Fargesia nitida was conducted in Jiuzhaigou in 2009 and it was found that the flowered Fargesia nitida populations were distributed on middle and upper slopes of Yingzhuadong at the elevation of 3 000 m and more.The flowering populations showed conspicuous declining characteristics.About 22%~29% of stems were flowering.The mean density of spicae was about 296 seeds·m-2.The mean density of seeds was about 3 923 seeds·m-2.Flowers of Fargesia nitida were raceme.Most of the flowers were green.Yellow and yellow-green ones were less than green ones.The green-purple flowers were the least.There were 10~19 flowers and 130~250 seeds per raceme.The mean number of seeds per flower was about 13.
