Fig. 5From: Environmental and genetic effects on tomato seed metabolic balance and its association with germination vigorPCA of seed metabolic content with germination percent. PCA of metabolic content of the seed distinguishes between poorly and highly germinating seeds, but not between SDF and SDS. Dots are located on axis according to PCA of primary metabolite content. Full circles represent SDF and empty tringles represent SDS. Dots are colored by final germination percentage, as indicatedBack to article page
