FIG. 6.

DA biplot showing group centroids, isodensity circles, and correlations of fungal species for fungal assemblages in the control and the metalaxyl treatments, at the end of the first and the fifth cycles of cucumber growth. Group A, control in the first cycle; group B, metalaxyl in the first cycle; group C, control in the fifth cycle; group D, metalaxyl 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 (−0.34, 0.16); 2, C. cladosporioides (−0.32, 0.18); 3, C. cerealis (0.03, −0.19); 4, C. fuckelii (0.11, 0.07); 5, C. destructans (−0.01, 0.14); 6, V. nigrescens (−0.19, −0.26); 7, F. equiseti (−0.28, 0.22); 8, F. oxysporum (0.21, 0.70); 9, F. solani (−0.02, 0.37); 10, F. tabacinum (0.05, 0.04); 11, G. roseum (−0.07, 0.52); 12, M. mucidum (0.11, 0.16); 13, M. alpina (−0.17, 0.31); 14, M. hiemalis f. hiemalis (0.44, 0.36); 15, M. racemosus f. racemosus (−0.21, 0.21); 16, M. roridum (−0.13, 0.19); 17, M. verrucaria (−0.33, 0.28); 18, P. marquandii (−0.11, 0.00); 19, P. rugulosum (−0.12, 0.32); 20, P. humicola (−0.33, 0.12); 21, S. coccosporum (−0.09, −0.78); 22, T. hamatum (−0.24, 0.16); 23, T. harzianum (−0.20, 0.63); 24, T. beigelii (0.16, 0.16); 25, V. chlamydosporium (−0.02, 0.74); 26, Exophiala sp. (0.07, −0.42); 27, Mycelium sterile moniliaceum 1 (− 0.10, −0.61), 28, H. fuscoatra (0.12, −0.12), 29, P. canescens (0.19, −0.03), 30, S. chartarum (−0.17, −0.25), 31, T. angustata (0.16, 0.13), 32, Mycelium sterile moniliaceum 2 (−0.04, 0.12), 33, Mycelium sterile dematiaceum 4 (−0.15, −0.27). The three canonical variates accounted for 54.3, 33.3, and 12.4% of the total variation, respectively.
