Influence on Agronomical and Physiological Characteristics of Flue-cured Tobacco under Waterlogging Stress of Volcanic Ash Soil and Paddy Field Soil at the Root Extending Stage

摘要: 以烤烟品种云烟87为材料,采用云南火山灰土、水田土为试供土壤。在盆栽条件下研究烤烟伸根期不同程度淹水胁迫对其农艺性状及相关生理指标的影响。试验结果表明,在相同的淹水胁迫程度下,火山灰土种植的烤烟物理特性及根系生长所受的不利影响均小于水田土,受抑制的严重程度与胁迫程度成正比。2种土壤处理的根系活力均受抑制,但并无较大差异。叶绿素含量与硝酸还原酶活性均属火山灰土种植的烤烟较高,但硝酸还原酶受抑制程度与胁迫程度呈反比。Abstract: The influence of waterlogging stress on agronomical and physiological characteristics in flue-cured tobacco at the root extending stage were studied with cultivar yunyan87 under pot experiment with volcanic ash and paddy field soil from Yunnan Province.The results showed that in the same degree of waterlogging stress,agronomical characteristics and root growth of the flue-cured tobacco grown in volcanic soil suffered the adverse effects less than flue-cured tobacco grown in paddy field soil,the suppression suffered serious degree proportional to the stress level.The root activity of two soils is inhibited,but it is no significant difference.Chlorophyll content and NR activity are volcanic ash soil grown flue-cured tobacco higher,but is inversely proportional to the degree of NR activity suppression suffered by the degree of stress.
