Species Specific Responses to Age on Nodule Formation, Seedling Growth, and Biomass Production of Acacia auriculiformis at Nursery Stage

Figure 1

Principal component ordination of nodulation responses and biomass production of A. auriculiformis. The horizontal axis of the ordination plot shows the first principal component (PC1) with an eigenvalue of 5.59, explaining 69.9% of total variation in nodule formation and biomass production; the vertical axis shows the second principal component (PC2) with an eigenvalue of 1.82, explaining 22.9% of total variation of nodule formation and biomass production.
