A Study of Seedling Breeding for Bambusa changningensis Yi et B.X.Li

In this paper,the breeding method of seedlings was studied for the new variety of sympodial bamboos(Bambusa changningensis Yi et B.X.Li).The results showed that 2-year-old mother bamboos were slightly higher than 1-year-old ones for their shoot ratio and adult bamboo number.The average number of adult bamboos could reached 7.9.2-year-old mother bamboos were the best choice for bamboo breeding.In the case of acking mother bamboos,it was possible to choose 1-year-old mother bamboos, which could also achieve high bamboo shoot rate and adult bamboo number.The different treatments of culms and stumps had a significant influence on bamboo shoot rate and adult bamboo number.Culms with incisions and stump treatments were the best.
