FIG. 4.

DA biplot showing group centroids, isodensity circles, and correlations of fungal species for fungal assemblages in the control and the CHA0-Rif treatments, at the end of the first and the fifth cycles of cucumber growth. Group A, control in the first cycle; group B, CHA0-Rif in the first cycle; group C, control in the fifth cycle; group D, CHA0-Rif in the fifth cycle. Fungal species names (values in parentheses are correlation with axis 1 and correlation with axis 2, respectively): 1, A. roseo-griseum (0.30, 0.02); 2, C. cladosporioides (0.14, 0.32); 3, C. cerealis (0.10, 0.09); 4, C. fuckelii (−0.10, 0.28); 5, C. destructans (−0.02, −0.11); 6, V. nigrescens (0.26, 0.04); 7, F. equiseti (0.13, 0.52); 8, F. oxysporum (−0.42, 0.52); 9, F. solani (−0.12, 0.41); 10, F. tabacinum (−0.11, 0.12); 11, G. roseum (−0.14, 0.23); 12, M. mucidum (−0.14, −0.11); 13, M. alpina (−0.08, 0.40); 14, M. hiemalis f. hiemalis (−0.49, 0.12); 15, M. racemosus f. racemosus (0.11, 0.66); 16, M. roridum (0.02, 0.13); 17, M. verrucaria (0.04, 0.40); 18, P. marquandii (0.09, 0.31); 19, P. rugulosum (−0.03, 0.36); 20, P. humicola (0.13, 0.51); 21, S. coccosporum (0.47, −0.36); 22, T. hamatum (−0.06, 0.49); 23, T. harzianum (−0.26, 0.44); 24, T. beigelii (−0.09, 0.28); 25, V. chlamydosporium (−0.48, 0.70); 26, Exophiala sp. (0.22, −0.18); 27, Mycelium sterile moniliaceum 1 (0.41, −0.14); 28, H. fuscoatra (0.01, 0.37); 29, P. canescens (−0.11, − 0.02); 30, S. chartarum (0.20, −0.22); 31, S. cylindrospora (0.09, 0.50); 32, T. angustata (−0.07, 0.31); 33, Mycelium sterile moniliaceum 2 (−0.06, −0.42); 34, Mycelium sterile dematiaceum 4 (0.19, −0.22). The three canonical variates accounted for 74.0, 19.6, and 6.4% of the total variation, respectively.
