PLS-DA score scatter plots of the MS-NMR fused data of B. intermedia seasonal harvests and the correlation with the environmental factors. Samples are categorized according to the values of observations for environmental factors. (A) Temp = temperature (°C); (B) Rad = Solar radiation (kJ/m2); (C) Humi: relative humidity (%) and (D) Rain = rainfall (mm). Sample seasons: Summer (Bi1, Bi7 and BiS); Autumn (Bi2, Bi3, Bi8 and Bi9); Winter (Bi4, Bi10 and BiW) and Spring (Bi5, Bi6, Bi11 and Bi12).
