根据Beakbame.Taper等人测定的七种砧木十项矮化效应预选指标建立的相关矩阵,进行了主成份分析,通过分析,淘汰了为矮化效应仅提供1％信息的根皮率、根皮部纤维等五项预选指标,肯定了根木质部中纤维、薄壁细胞等非输导组织所占的比例是矮化效应的主要因素,并根据根木质部中纤维、薄壁细胞、导管、枝条电阻、气孔密度各指标的因子负荷量权重分配矮化预选指标,可很好的反应矮化效应。
According to the correlation matrix established by Beakbame.Taper et al., The preliminary dominance index of ten dwarfing effects of seven rootstocks, the principal component analysis was carried out. By analyzing, the root bark rate, root bark The results showed that the ratio of non-conductive tissues such as fiber and parenchyma in root xylem was the main factor of dwarfing effect. According to the results of five pre-selection indexes, the proportion of fiber, parenchyma cells, catheters, shoot resistance , Stomatal density of the indicators of the load factor weight distribution dwarf preselected indicators, can well reflect the dwarfing effect.
