摘要: 为明确不同基因型烟草氯离子吸收、积累与分配的差异,筛选出氯高吸收和低吸收基因型的烟草种质,采用盆栽试验,选取9个烤烟品种为试材,设置3个施氯水平处理(0、50、100 mg/kg),分析烟草成熟期不同部位氯离子吸收、积累、转运、分配特性。结果表明,随着施氯量增加,烟草各部位氯离子含量上升,烟草各部位氯离子含量表现为脚叶>下部叶>中部叶>上部叶>茎>根,其中,K326叶片总体氯离子含量和积累量均较高,分别为206.4 mg/kg和16.58 mg;渝金香1号中、上部叶氯离子含量较低,分别为150.09mg/kg和95.00 mg/kg,脚叶(1.35 mg)和下部叶(4.63 mg)氯离子积累较高;在50、100 mg/kg氯处理下,辽烟17 叶片氯离子含量、积累量和转运系数较CK 分别增长59.62%、95.67%,37.04%、52.49% 和39.88%、89.43%,渝金香1 号氯离子转运系数仅增长7.88% 和12.90%,秦烟96 氯离子积累量和分配率仅增长1.73%、2.04%和0.05%、0.07%,与CK相比差异不显著。总体上,在参试9个烟草品种中,秦烟96、渝金香1号烟株氯离子吸收、积累量较小,中、上部叶氯离子转运分配较少,可在土壤氯离子含量较高的烟区种植;K326、辽烟17对氯离子吸收量较大,烟株各部位氯离子含量较高,在生产上应采取相应控氯措施。

Abstract: To clarify the differences of chlorion absorption,accumulation and distribution in tobacco with different genotypes,and to screen tobacco genotypes with high and low chlorion absorption,in this study,nine flue‑cured tobacco varieties were selected as test materials,and pot experiments were conducted with three chlorine application levels( 0,50,100 mg/kg )to determine the characteristics of chlorion absorption,accumulation,transportation and distribution in different parts of tobacco at maturity stage.The results showed that the content of chlorion in different parts of tobacco increased with the increase of chlorine application rate,and the content of chlorion in different parts of tobacco was foot leaf> lower leaf>middle leaf>upper leaf>stem>root.Among them,the total chloride content and accumulation in K326 leaves were higher,which were 206.4 mg/kg and 16.58 mg,respectively. The content of chloride in the middle and upper leaves of Yujinxiang No.1 was lower,which were 150.09 mg/kg and 95.00 mg/kg,respectively.The chlorion accumulation in the foot leaves(1.35 mg )and lower leaves(4.63 mg)was higher.Under 50 and 100 mg/kg chlorine treatments,the content,accumulation and translocation coefficient of chlorion in leaves of Liaoyan 17 increased by 59.62%,95.67%;37.04%,52.49% and 39.88%,89.43% compared with CK,respectively.The chlorine transport coefficient of Yujinxiang No.1 only increased by 7.88% and 12.90%.The accumulation and distribution rate of chlorion in Qinyan 96 increased only by 1.73%,2.04% and 0.05%,0.07%,with no significant difference compared with CK.In general,among the nine tobacco varieties tested,Qinyan 96 and Yujinxiang No.1 have less chlorion absorption and accumulation,less chlorion transport and distribution in the middle and upper leaves,and can be planted in tobacco areas with higher soil chloride content. K326 and Liaoyan 17 have larger absorption of chlorion,and the chlorine content in each part of tobacco plant is higher,so corresponding chlorine control measures should be taken in production.
