Radar plot of odor response intensity of alfalfa (A). OPLS-DA analysis of odor response intensity of alfalfa (B) Q2 = 0.923, R2 = 0.969, R2X = 0.748. X: budding stage. C: early flowering stage. S: full flowering stage. Radar plot demonstrate the response intensity of each group at different sensor channels, and the circles in the OPLS-DA score plots indicate 95% confidence intervals
