Some species of cover crops produce phenolic compounds with allelopathic potential. The use of
math, statistical and computational tools to analyze data obtained with spectrophotometry can assist in the
chemical profle discrimination to choose which species and cultivation are the best for weed management
purposes. The aim of this study was to perform exploratory and discriminant analysis using R package
specmineonthephenolicprofleofSecalecerealeL.,AvenastrigosaL.andRaphanussativusL.shootsobtained
by UV?vis scanning spectrophotometry. Plants were collected at 60, 80 and 100 days after sowing and at 15
and 30 days after rolling in experiment in Brazil. Exploratory and discriminant analysis, namely principal
component analysis, hierarchical clustering analysis, t-test, fold-change, analysis of variance and supervised
machine learning analysis were performed. Results showed a stronger tendency to cluster phenolic profles
according to plant species rather than crop management system, period of sampling or plant phenologic
stage. PCA analysis showed a strong distinction of S. cereale L. and A. strigosa L. 30 days after rolling. Due
to the fast analysis and friendly use, the R package specmine can be recommended as a supporting tool to
exploratory and discriminatory analysis of multivariate data. |
