基于SPAD值的木薯叶绿素含量预测模型
A Model for Predicting Chlorophyll Content in Cassava Based on SPAD Values
摘要
Abstract
In order to investigate a non-destructive and quick measuring method for chlorophyll content in cassava, a model for predicting total chlorophyll content that was based on SPAD values,specific leaf area, chlorophyll content was established. The results indicated that the influence of chlorophyll A to SPAD values was larger than chlorophyll B; specific leaf area and leaf position and SPAD values and chlorophyll content showed significant correlation; added specific leaf area and leaf position, the accuracy of the model for predicting total chlorophyll content was improved; based on SPAD values,specific leaf area and leaf position, the model for predicting total chlorophyll content was established as C=-4.51+0.092 5 Sp+0.039 9 Sa+0.145 0 (Lp).关键词
