摘  要：
对雪茄外包皮烟在大田生长过程中的农艺性状与根系伤流强度进行了相关、回归和通径分析。相关分析结果表明,根系伤流强度与株高、茎围、节距、叶面积、叶干重、根体积、根干重呈极显著正相关,相关系数分别为0.8449、0.8552、0.8379、0.8215、0.8204、0.8442、0.7156;茎干重与根系伤流强度呈显著正相关(r=0.6926)。回归和通径分析结果表明,株高、叶面积、根体积、根干重是影响根系伤流强度的主要因素。

摘  要：
Correlation,regression,and path analysis between agronomic attributes in cigar wrapper tobacco and its roots bleeding intensity during field growth were conducted.The correlation analysis showed that plant height,stem length,length of joins of main stem,leaf area,leaf weight,root volume,and root weight were related to the root bleeding intensity positively and correlation coefficients were significantly different,which were 0.8449**、0.8552**、0.8379**、0.8215**、0.8204**、0.8442**、0.7156** respectively.Dry weight of stem was related to the roots bleeding intensity positively and correlation coefficient of dry weight of stem with the roots bleeding intensity was different(r=0.6926*).The result of path analysis and regression indicated that plant height,area of leaf,volume of root,and dry weight of root were key factors for the roots bleeding intensity.
