摘要
[目的]研究烤烟叶片的生长规律.[方法]以烤烟G80为试验材料,利用2014-2016年烤烟育苗、大田栽培的试验数据,分析烤烟不同时期、不同部位叶片生长规律.[结果]烤烟新生叶片全日生长量不断加速,依次成为全株生长速度最快的叶片,然后,依次进入不可逆转的生长减速.各叶位叶片长度和宽度最快生长期均在从主要依靠功能叶片输入有机物生长向主要依靠自身光合作用合成有机物生长期间出现.指出烤烟叶片生长过程中长度和宽度增加、叶面积增加、干物质增加最快时期和光合生产率最高时期依次出现,烤烟不同品种、不同部位叶片因外形不同和同一叶片不同时期因外形变化叶面积校正系数不同.[结论]该研究可为烤烟叶片生长规律进一步研究提供参考.
Abstract
[Objective]The aim is to study leaf growth rhythm of flue-cured tobacco.[Method]Using flue-cured tobacco G80 as test materials,growth rhythm of different parts leaf was analyzed during different growth period based on data of flue-cured tobacco breeding and field cultivation during 2014-2016.[Result] Young flue-cured tobacco growth accelerated to increase,they became the leaves which grew fastest successively.Then,the growth of them decelerated irreversibly.Leaf length and width grew fastest when flue-cured tobacco growth depending function leaves input organic compounds converted into depending photosynthesis to synthesize organic compounds.In the process of growing,the order of maximum growth period was leaf length and width increasing,leaf area increasing and dry matter increasing,photosynthesis productivity.The correction coefficient of leaf area was different because of shape change caused by different variety and different parts of leaf,growth period of same leaf.[Conclusion]The research can give reference for further studying leaf growth rhythm of flue-cured tobacco.
