图1. 经3种保存液和3种程度充气处理后泥炭藓孢子的萌发率保持率(平均值±标准误差)。A, 尖叶泥炭藓(Sphagnum capillifolium)。B, 喙叶泥炭藓(Sphagnum flexuosum); PW, 泥炭地表水; SW, 泥炭藓沥出液; UW, 超纯水。0, 不充气; 1, 低速率充气; 2, 高速率充气。*表示不同分组内(UW0、PW0和SW0; UW0、UW1和UW2; PW0、PW1和PW2; SW0、SW1和SW2; Air和UW0)的处理间有显著差异(p < 0.05)。
Fig. 1. Germination conservation rate of Sphagnum spores after three types of storage solutions and three levels of air injection. (mean ± SE) A, S. capillifolium. B, S. flexuosum PW, peatland surface water; SW, Sphagnum leachate water; UW, ultrapurewater. 0, no air injection; 1, low air injection; 2, high air injection. * in each group (UW0, PW0 and SW0; UW0, UW1 and UW2; PW0, PW1 and PW2; SW0, SW1 and SW2; Air and UW0) indicated significant differences in one-way ANOVA (p < 0.05).
