| Abstract: | This paper deals with the geographical variations in DBH and the height of young bamboos for phyllostachys heterocycla cv. pubescens in two dimension of latitude and longitude, which was analyzed by trendface,through measuring the growth characters including height,diameter and the quantity of young bamboos from different provenances for five years.The mother bamboos collected from eight provinces in which Phyllostachy heterocycla cv. Pubescens distribute, 16 provenances were divided into northern zone,middle zone and southern zone.The provenance tests were carried out in Jianou city and Huaan county,Fujian province.The results showed that there was an obvious geographical variation trend in the DBH of new bamboo,average number of bamboo shoot and the quantity of new bamboos. |
