- 摘要:
- 以“红提”、“紫提”、“解百纳”3个品种葡萄为试材,采用SPAD-502叶绿素仪与分光光度法分别测定葡萄叶片的SPAD值与叶绿素含量,研究了不同品种葡萄叶片SPAD值与叶绿素含量的相关性。结果表明:3个品种葡萄叶片SPAD值与叶绿素a、叶绿素b以及总叶绿素含量间均存在极显著正相关关系;通过线性回归得出了SPAD值与叶绿素a、叶绿素b以及总叶绿素含量间的回归方程;经研究3个品种葡萄叶片叶绿素含量的实测值与回归方程的预测值之间均无显著性差异,采用回归方程,通过SPAD值可以预测不同品种葡萄叶片的叶绿素含量。
- Abstract:
- ‘Cabernet Cortis’,‘Purple Globe’,‘Red Globe’of three grapes were used as materials,SPAD-502 chlorophyll meter and spectrophotometry were used to determine the SPAD value of grape leaves and chlorophyll content,correlation between chlorophyll content of different varieties of grape leaf and SPAD values was studied.The results showed that,the chlorophyll a,chlorophyll b and total chlorophyll content of 3 varieties of grape leaf were very significant positive correlation with SPAD values.Through linear regression SPAD values were given and the regression equation of chlorophyll a,chlorophyll b and total chlorophyll content.Through the test and research of 3 varieties of grape leaf chlorophyll content values were not significantly difference between predicted values and regression equation,using the regression equation,the prediction of chlorophyll content in leaves of different varieties of grapes could be distinguished by SPAD.
