摘要:

收集全国毛竹分布区北带、中带、南带8省16个种源的母竹,在福建建瓯市和华安县进行种源试验。经过5a连续观测不同种源的发笋成竹数量及新竹胸径、高度等生长指标,应用趋势面分析毛竹种源胸径等性状在经纬2维方向的地理变异,结果表明,毛竹种源的新竹胸径、平均发笋数和新竹数存在明显的地理变异趋势。

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.

Key words: Phyllostachys heterocycla cv. pubescens provenance, Trendface analysis, Growth of new bamboo, Geographical variation
