烤烟不同时期叶片生长规律研究
Study on Leaf Growth Rhythm of Flue-cured Tobacco
摘要
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.关键词
