含油量对提高菜油产量有十分重要的意义, 传统的高含油油菜新材料筛选方法工作量大, 耗时长。为找出一种快速诊断高含油油菜育种材料的新方法, 本研究以3组不同含油量的9个甘蓝型油菜为材料, 测定其不同生育期的高光谱反射率与叶绿素含量, 分析其内在关联。研究发现, 油菜高光谱反射率在可见光波段呈现出“两峰三谷”特性, 幼苗期含油量越高则高光谱反射率越低。叶绿素a含量是导致总叶绿素含量差异的主要原因。在490 nm和670 nm处, 幼苗期光谱反射率和叶绿素含量负相关, 相关系数分别为-0898和-0783；叶绿素和含油量显著正相关, 相关系数达到0962；490、560、670 nm反射率和含油量之间呈负...

The oil content of rapeseed is important for improving oil yield And the traditional method for new oilseed rape materials is complex and time-consuming In order to find a new method for rapid diagnosis of oilseed rape breeding materials, 3 groups of 9 different oil content Brassica napus lines were uesed as raw materials, meanwhile, hyperspectral reflectance and chlorophyll were tested in different stage and the relationship between them was analyzed The results showed that the hyper spectral reflectance of rape displays two peaks and th...
