Biogeographic Variability in Kernel Oil and Press Cake Content of Beauty Leaf Tree (Calophyllum inophyllum L.), as Determined by Chemical and Near-Infrared Spectroscopy Analysis

The aim of this study was to evaluate biogeographic variability in the fruit, kernel, kernel-oil and press-cake contents 50 accessions beauty leaf tree (C. inophyllum L.) collected from 19 locations spanning 4000 km along eastern northern coasts Australia (Northern Territory Queensland). Mature fallen fruits C. were individual trees stored a shed for over year. cracked open extract kernels, kernels crushed 5–10 mm. NIR spectra using FT–NIR. Results showed large variation between provenances oil, resin cake contents. Most genotypes separated based on their fingerprint PCA PLS-DA. It concluded that spectroscopy not only aids screening numbers genotypes, but it also allows preservation tested seeds further propagation. This feature will have greatest advantage plant breeding commercial cultivation, as contain high oil content could be sown help establish plantations with oil-production capacity. Overall, differences can predicted spectra. Furthermore, used tool define provenance variations kernel tree.
