The pro­duc­tion of oil palm clones via tis­sue cul­ture tech­nique will increase pro­duc­tiv­ity and yield of the oil crop by pro­vid­ing elite and uni­form mate­r­ial for the indus­try. To exploit their full poten­tial, these clones need to be planted on prime acreage. How­ever, lim­i­ta­tion of arable land has pushed oil palm grow­ers towards more chal­leng­ing envi­ron­ment such as peat soil. In this study, oil palm clone P325 planted on peat and min­eral soil tri­als were sub­jected to metabolome and mul­ti­vari­ate analy­ses to cap­ture their response to their plant­ing sites. The inves­ti­ga­tion recorded spear leaf metabolome dif­fer­en­ti­a­tion accord­ing to the field tri­als of dif­fer­ent soil types, marked by the asparagine and dopamine abun­dance dif­fer­ence in prin­ci­pal com­po­nent analy­sis (PCA) load­ings plot. Liq­uid chromatography-mass spec­trom­e­try (LC-MS) demon­strates a sen­si­tive and rapid method in acquir­ing infor­ma­tion that to date has been scarce for this impor­tant crop. Mul­ti­vari­ate sta­tis­ti­cal analy­sis of PCA fur­ther enables the visu­al­i­sa­tion of the chem­i­cal dis­tinc­tion of the tis­sue from the com­plex data.
