摘要: 對(duì)雪茄外包皮煙在大田生長(zhǎng)過(guò)程中的農(nóng)藝性狀與根系傷流強(qiáng)度進(jìn)行了相關(guān)、回歸和通徑分析,。相關(guān)分析結(jié)果表明,，根系傷流強(qiáng)度與株高、莖圍,、節(jié)距,、葉面積、葉干重,、根體積,、根干重呈極顯著正相關(guān)，相關(guān)系數(shù)分別為0.8449**,、0.8552**,、0.8379**、0.8215**,、0.8204**,、0.8442**、0.7156**,；莖干重與根系傷流強(qiáng)度呈顯著正相關(guān)(r=0.6926*),。回歸和通徑分析結(jié)果表明,，株高,、葉面積、根體積,、根干重是影響根系傷流強(qiáng)度的主要因素,。Abstract: 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.
