摘要： 为筛选出合适的立体绿化载体和侧蒴藓类种类,本文将羽枝青藓(Brachythecium plumosum)、灰藓(Hypnum cupressiforme)、细叶小羽藓(Haplocladium microphyllum)、密叶绢藓（Entodon compressus）和中华细枝藓（Lindbergia sinensis）5种侧蒴藓类植物的配子体碎片撒播于表面有薄层蛭石泥炭土的棕榈垫上。结果表明,在保湿的环境中,2个月后所有种均能形成绿色藓丛,并与立体绿化载体上的基质紧密结合。为比较它们的生长和繁殖能力,测定了这5种藓丛的叶绿素荧光参数（初始斜率、半饱和光强、最大相对电子传递速率）,藓丛配子体的盖度、长度,单位面积配子体鲜质量和干质量及叶绿素含量等生长指标,并首次运用根系分析软件（WinRHIZO）定量地测定了单位面积内5种藓类的表面积、茎枝总长度、平均直径、总体积、枝尖数、枝分叉数等指标。统计分析结果显示,5种藓类植物的生长和繁殖能力综合指数排序依次为羽枝青藓、细叶小羽藓、灰藓、密叶绢藓和中华细枝藓, 它们可以作为今后屋顶和墙体立体绿化材料使用。WinRHIZO根系分析软件可用于侧蒴藓类植物配子体生长指标的测定,此法简便易行,在侧蒴藓类植物的生理生态学研究中具有应用价值。
Abstract: Pleurocarpous mosses have their own preponderance as vertical greening plants because of their special morphological, physiological and ecological traits. Practical vertical greening carriers and suitable  pleurocarpous mosses should be developed before their application at a large scale. Palm pads with thin layer of peat and vermiculite were chosen as vertical greening carriers in the present work. Gametophytic fragments of five pleurocarpous mosses, which included Brachythecium plumosum, Hypnum cupressiforme, Haplocladium microphyllum, Entodon compressus and Lindbergia sinensis, were sown onto the pads in a humid greenhouse with 80% relative humidity. After a two-month cultivation in the greenhouse, chlorophyll fluorescent parameters (initial slope, half-saturation light intensity, maximal relative electronic transfer rate), and the gametophytic coverage, length, fresh mass, dry mass, chlorophyll content were measured. By using the WinRHIZO root system analyzer, the total area, length of stems and branches, diameter of stems and branches, volume, tip number and branch number of gametophytes were also measured. Based on the above indices, an evaluation model revealing the growth and reproduction capacity of five mosses was designed. Finally, their growth and reproduction capacities were compared based on the model.
The results showed that all five pleurocarpous mosses were able to form green cushions from their gametophytic fragments in moisture environments after a two-month cultivation. The cushions closely integrated with the matrix on the pads. The palm pads with thin layer of peat and vermiculite are of potential and practical value as vertical greening carriers. Based on their integrated indices from high to low, five mosses were ranked as B. plumosum, H. microphyllum, H. cupressiforme, E. compressus and L.  sinensis. These mosses could be applied as vertical greening plants. The present study also showed that, WinRHIZO analysis software can be used to determine the growth indexes of pleurocarpous moss gametophytes. The method is simple and of potential value in physiological and ecological studies of pleurocarpous mosses.
