Phenogram of 80 phosphate solubilizing fluorescent pseudomonads based on their carbon source utilization profiles. The clustering was done using sequential, agglomerative, hierarchical and nested (SAHN) method. The pairwise coefficient of similarity (Dice) was used for clustering with the UPGMA algorithm using NTSYSpc2.02a software. The phenogram resulted into 3 major phenon at 0.76 smilarity coefficient. The experiment was done with three replicates.
