摘要
研究平顶后增温对烤烟上部叶生长发育相关氨基酸含量和酶活性的影响,为促进上部叶生长发育,提高烟叶产量产值提供参考。以云烟116为试验材料,共设置2个处理:云烟116常温(T1);云烟116大棚增温(T2),研究上部叶胞壁羟脯氨酸(Hyp)含量、胞壁过氧化物酶(POD)活性、吲哚乙酸氧化酶(IAAO)活性对增温的响应。结果显示,平顶后增温能够显著地降低上部叶胞壁Hyp含量、胞壁POD活性和IAAO活性,提高上部叶叶长、叶宽和叶面积,增加上部叶的产量和产值,T2与T1相比,分别提高了8.6%、3.9%、12.9%、7.0%和13.8%。平顶后适当增温能够有效地促进烤烟上部叶生长发育。
By studying the effects of warming after topping on the amino acid content and enzyme activity related to growth and development of the upper leaves of flue-cured tobacco,we aim to provide a reference for promoting the growth and development of upper leaves and increasing the yield of tobacco leaves.Having flue-cured tobacco variety Yunyan 116 as an experimental materials,two treatments was set:the normal temperature(T1)and warming treatment(T2).The hydroxyproline content and POD activity in cell wall as well as IAAO activity in the upper leaves of the two treatments were measured.The results showed that warming after toping effectively reduced the content of hydroxyproline,cell wall POD activity and IAAO activity in the upper leaves of tobacco leaves.The length,leaf width,leaf area,the yield and production value of the upper leaves for T2 treatment increased by 8.6%,3.9%,12.9%,7.0%,and 13.8%,compared with T1.In sum,the upper leaves development of flue-cured tobacco can be promoted significantly through warming properly after toping.
