摘要
应用主分量分析法对2个试点的麻竹Dendrocalamus latiflorus地理种源进行研究评价,并同经营目的和造林区的条件,评选优良种源.结果表明,选择的优良种源现实增益显著,入选的4个优良笋用种源,主要性状平均现实增益达1.19%～32.46%;入选的4个优良材用种源,主要性状平均现实增益为4.11%～39.74%.
Principal component analysis was used to study and evaluate the geographical provenances of Dendrocalamus latiflorus in two pilot fields. Excellent provenances were selected according to different management purposes and different conditions of afforestation areas. The results showed that real gains of the selected provenances were significant. The average real gains of main characteristics of four selected provenances for bamboo shoots were between 1.19% and 32.46% ; those of four selected timber-use provenances were between 4.11% and 39.7%.
