摘要
以10年生的泡桐无性系测定林为研究材料,通过相关遗传力的通径分析表明:叶部性状与泡桐无性系的材积、胸径、树高的生长有着密切关系。叶面积大、叶干重小、叶柄短、叶基凹入较深是材积和胸径速生的标志;叶面积小,叶柄较长、叶基较宽是树高速生的标志。
By the correlative heritability path analysis of characteristic in the leaf of 10 year old paulownia clones in relation to volume,diameter and height,the results show that the signs of rapid growing of volume and diameter are large leaf area,low leaf dry weight,short petiole and deep leaf base dint,and the signs of rapid growing of height are small leaf area,long petiole and wide leaf base width.
