图4 油松与大叶黄杨的叶际表生真菌在不同季节间的α多样性与纲水平群落组成。A: 油松的α多样性指数; B: 大叶黄杨的α多样性指数; C: 油松的NMDS分析; D: 大叶黄杨的NMDS分析; E: 油松的群落结构; F: 大叶黄杨的群落结构。箱线图中的不同小写字母表示组间差异显著(Kruskal-Wallis, P < 0.05)。r表示样点间的相似程度。r数值越大, 差异越大。

Fig. 4 The diversity and class level community structure of epiphytic fungi in the phyllosphere of Pinus tabuliformis and Euonymus japonicus across different seasons. A, The alpha diversity index of P. tabuliformis; B, The alpha diversity index of E. japonicus; C, Non-metric multidimensional scaling analysis of P. tabuliformis; D, Non-metric multidimensional scaling analysis of E. japonicus; E, The community structure of P. tabuliformis; F, The community structure of E. japonicus. Different letters in the box plot indicates that there was significant difference between groups (Kruskal-Wallis, P < 0.05). The larger the value of, the greater the difference.
