摘    要:以马铃薯杂交种组合实生薯1代群体为材料,测定现蕾期叶片的SPAD值、叶绿素含量,进而分析了叶片SPAD值和叶绿素含量及单株产量的相关性。结果表明:SPAD值与叶绿素a、叶绿素b、总叶绿素含量和单株产量相关性达到了极显著水平,回归方程依次为:y=0.0472x-0.8102(r=0.8304**);y=0.013x-0.1848(r=0.7424**);y=0.0601x-0.9948(r=0.8221**);y=23.22x-736.76(r=0.496**)。表明叶片SPAD值可以很好的反映植株叶绿素含量和单株产量水平,而且测定SPAD值方法简便快捷,还不破坏叶片生长,可作为早期进行马铃薯产量选择的指标。

关 键 词:马铃薯  SPAD值  叶绿素含量  产量  相关性

Abstract:SPAD readings and chlorophyll contents in leaves of the first generation of crossed combination true seed potato were measured at bud stage,then the correlation between SPAD readings chlorophyll contents and single yield were analyzed.The results showed that correlation between SPAD readings and Chla,Chlb,Tchl,single yield are significant at 0.01 level respectively and the regression equation are: y=0.0472x-0.8102(r=0.8304);y=0.013x-0.1848(r=0.7424);y=0.0601x-0.9948(r=0.8221);y=23.22x-736.76(r=0.496),respectively.The conclusion showed that SPAD readings can fully reflect the chlorophyll contents and single yield,further more the measure process is simple and convenient without any harm on leaves,so SPAD readings is a useful index for selecting the high yield varieties in the early period
Keywords:potato(Solanum tubersosum L  )  SPAD readings  chlorophyll contents  yield  correlation
