在大田栽培和自然条件下，通过人工模拟的方式，研究增强UV-B辐射对云烟87和红花大金元花期和农艺性状的影响。结果表明，大田期增强UV-B辐射可推迟并缩短云烟87和红花大金元的花期；较低强度的UV-B辐射（1.06 KJ/m2）能促进红花大金元的烟株增高、茎围加粗、节距增长，并可显著增大云烟87的叶面积，较强的UV-B辐射（1.83 KJ/m2）可提高红花大金元的叶面积。

Fieldstudieswereconductedtotesttheeffectofenhancedultraviolet-B (UV-B,308nm,1.83kJ/m2,1.06kJ/m2)radiationonthe agronom ic traitsoftwo flue-cured tobacco cultivars (Hongda and Yunyan87) underfield cultivation and naturallightconditions.The results showed that enhanced ultraviolet-B radiation could delay and shorten Hongda and Yunyan87 flowering. Lower intensity of Ultraviolet-B radiation induced to higher height,longer stem circum ference and node distance of Hongda,and increased leaf area of Yunyan87. Strong Ultraviolet-B radiation could increase the leaf area of Hongda.
