利用樟子松(Pinus sylvestris L.Var.mongolica Litvin)9个种源在7个参试点的生长性状,进行多点试验的联合方差分析,结果表明:种源与地点间存在显著的交互作用;采用Tai法和生产力指数(PQI)法,对各种源进行稳定性测定和生产力评价,为樟子松自然分布区和引种区分别选出了优良种源。其中,高峰、卡伦山种源的生产力最高,适应性也较强,在东北平原、东北东部山地及小兴安岭等引种地区有广阔的推广前景;金山种源的遗传稳定性强、产量较高,可在大兴安岭西北部的樟子松自然分布区推广。
The results showed that there was a significant interaction between the provenance and the locality through the multi-point analysis of the growth traits of nine provenances of Pinus sylvestris L. Var. Mongolica Litvin at seven test sites. The Tai method and the productivity index (PQI) method were used to evaluate the stability and productivity of various sources, and the best provenances were selected for the natural distribution area and introduced area of Pinus sylvestris var. Mongolica. Among them, the highest peak, the Karon mountain provenance has the highest productivity and adaptability, and has broad promotion prospects in the northeast plains, the mountains in the northeastern part of the country and the small Xingan Mountains. The Jinshan provenances have high genetic stability and high yield, It can be popularized in the natural distribution area of Pinus sylvestris in the northwest of Daxinganling.
