叶绿素仪CCM-200在测定茶树叶片叶绿素和氮素含量上的应用
Estimate of leaf chlorophyll and nitrogen content in Camellia sinensis by CCM-200
摘要
Abstract
Chlorophyll meters is an effective tool to determine chlorophyll and nitrogen contents in plant leaves quickly and nondestructively. In this study, the chlorophyll and nitrogen contents of the leaves in Camellia sinensis were determined by spectrophotometer method and Micro-Kjeldahl method. The correlations between them and CCI (chlorophyll content index) values obtained by CCM-200 were analyzed. The result showed liner correlation between CCI values and chlorophyll contents. The determination coefficients (R2) of CCI values (chlorophyll a, chlorophyll b) and total chlorophyll contents (0.972 8, 0.858 6 and 0.9774, respectively) by mg·cm-2 as unit were higher than that by mg·g-1 as unit. The chlorophyll contents of different varieties were obvi ously different, but significant linear correlations still appeared. Significant linear correlation was also observed between CCI values and nitrogen contents with 0.9828 of R2. In a word, CCM-200 has a good applicability of estimating the chlorophyll and nitrogen contents.关键词
