摘要
2004年通过对山杏、山樱桃、大白柠条、杨柴不同种源1 a生苗的生长量、物候期、生物量等性状的调查、观测,对数据进行方差、相关分析结果表明:4个树种各种源的苗高、地径生长存在显著差异。高生长节律有各自的特点。地径、侧枝数和受害率等性状之间存在相关关系。估算各种源的综合指标并初步筛选出各树种适合内蒙古呼和浩特及其毗邻地区生长的最佳种源,为良种选育奠定了科学依据。
In 2004, 1-year-old seedling traits of Siberian apricot, Japanese Flowering cherry, Korshinsk Pea-shrub and Hedysartan laeve Maxim. from different provenances were analyzed with statistical methods, such as variance and correlation. The results showed that there is very significant differences among provenances in seedling height and diameter. The rhythm of height＇s growing among provenances has respective feature. There is significant correlation between diameter, branch, wounded coefficient and so on. The index of each provenance were estimated and the best provenance of each species in the middle and west of Inner Mongolia was picked out. All of these provides scientific basis for choosing the best species.
