| 摘 要： | 为了对宜宾市烟区及类似烟区筛选优良新品种及培育壮苗提供理论依据,采用相关分析、通径分析等统计方法对新近育成的烤烟新品种移栽前根系长度、宽度、根数、根面积、根体积、干物质等指标相互之间的关系进行分析.结果表明:根系长度、根系数量对干物质积累影响作用较大,其他根系构成因素的影响相对较小. |

| Abstract: | The relationships between roots length,roots width,root number,root area,root volume and dry matter of new tobacco varieties before transplanting were analyzed by using the correlation and path analysis to provide the theoretical basis for tobacco breeding and rearing sound seedlings in Yibin city and the similar ecological areas.The results showed that roots length and roots quantity had the significant effect on dry matter accumulation of tobacco seedlings and other roots composition factors had a little ... |
