The biplot model of the principle component analysis (PCA) for the comparison of condition A (green triangle), B (blue circle), C (red square), and D (yellow triangle) for whole seeds (left) and condition E (green triangle), F (blue circle), and G (red square) for ground seeds (right) along the storage period. The blue circle refers to the time point of 14th (2). The smaller black circles are those identified compounds from the GCMS.
