中国农学通报 2012,28(21):92-95 / Chinese Agricultural Science Bulletin 甘蓝型油菜SPAD值与叶绿素含量关系分析 张文英，王凯华 （长江大学农学院/长江中游湿地农业教育部工程研究中心，湖北荆州434025 ） 摘 要：以分属冬性、半冬性、春性类型的5 份甘蓝型油菜品种为材料，进行了2 年试验，比较了不同材料 间SPAD 值和叶绿素含量之间的差异，分析了SPAD 值与叶绿素含量的相关性，构建了二者之间的线性 回归关系，研究了两类指标在不同年份间的变异。试验结果表明，部分材料间SPAD 值差异极显著，叶 绿素a、叶绿素b 及叶绿素总量在部分材料间差异极显著，而类胡萝卜素含量在材料间无差异。甘蓝型 油菜SPAD 值与叶绿素含量之间的相关分析结果表明，SPAD 值与叶绿素含量呈正向显著相关，其中与 叶绿素总量相关程度最高(r=0.9082) ，其次是与叶绿素b 的相关(r=0.8366) 。SPAD 值及叶绿素含量年际 间差异性分析结果表明，两者受年际间环境影响较大。 关键词：甘蓝型油菜； SPAD 值；叶绿素含量；相关分析；回归分析 中图分类号：S565.04 文献标志码：A 论文编号：2012-1943 TheAnalysisofRelationshipBetweenSPADReadingandChlorophyllContentinBrassicanapusL. Zhang Wenying, Wang Kaihua (SchoolofAgriculture/EngineeringResearchCenterofWetlandAgricultureintheCentralYangtzeofMinistryofEducation, YangtzeUniversity, Jingzhou Hubei 434025) Abstract:Difference between SPAD value and chlorophyll content of various genotypes of Brassica napus was compared, correlation analysis was conducted upon SPAD value and chlorophyll content, and the variation between two years was studied using five rapeseed varieties belong to winter, semi-winter, spring type, respectively. Results showed that the difference of SPAD value, chlorophyll a, chlorophyll b and total chlorophyll among genotypes were very significant. However, there was not difference between the materials for the carotenoid content. Positive significant correlation between SPAD value and chlorophyll content was observed, among which the highest degree of correlation of was found between SPAD value and the total
