紫外辐射增加对小麦群体结构的影响

Impact of Enhanced UV B Radiation on Canopy Structure of Wheat

南京地区小麦田间紫外辐射试验表明 ,紫外辐射量的增大能显著影响小麦的群体结构 ,进而影响小麦对紫外辐射的反射与吸收。本文从小麦群体结构的角度对上述影响进行了详细的量化分析 ,并对产生这种影响的可能机制进行了探讨。

Field experiments performed in Nanjing area show that enhanced UV B radiation causes marked variations in canopy structure of wheat and in turn affects the canopy's light reflectance and absorption. Investigation has been conducted in detail and quantitatively on the variations of the structure and with possible mechanism under discussion.
