图2. 三种石斛不同处理下种子萌发率(A、D、G)、原球茎形成率(B、E、H)和幼苗形成率(C、F、I)(平均值±标准误差)。柱子上方不同小写字母表示同一阶段不同处理之间差异显著(α = 0.05)。OMA, 不接菌的燕麦琼脂培养基作为营养缺乏对照处理; MS, 不接菌的MS培养基作为营养丰富对照处理; SSCDO-5, 燕麦培养基上接种SSCDO-5菌株处理; FDd1, 燕麦培养基上接种FDd1菌株处理菌的处理。

Fig. 2. Percentage of seed germination (A, D, G), protocorm (B, E, H) and seedling (C, F, I) formation of different treatments in three Dendrobium species (mean ± SE). Different lowercase letters above the bars represent significant differences between different treatments at the same stage (α = 0.05). OMA, oatmeal agar medium without fungal inoculation was used as nutrient-poor control treatment; MS, MS medium without fungal inoculation was used as nutrient-rich control treatment; SSCDO-5, treatment of fungal inoculation with SSCDO-5 strain on OMA medium; FDd1, treatment of fungal inoculation with FDd1 strain on OMA medium.
