摘要
[目的]筛选抗旱能力强的苔藓植物用于城市立体绿化。[方法]对采自江西省井冈山自然保护区的10种藓类植物进行干旱胁迫,研究其在干旱胁迫后再复水过程中的植物体含水量及光合作用效率变化,分析其抗旱能力。[结果]10种藓类植物经干旱处理后均表现出相应的抗旱能力,其中密枝灰藓(Hypnum densirameum)、桧叶白发藓(Leucobryum juniperoides)、尖叶匐灯藓(Plagiomnium cuspidatum)和拟阔叶小石藓(Weisia platyphylloides)表现出较强的干旱适应能力。[结论]该研究结果为今后开展苔藓植物的规模化生产并应用于城市绿化提供了理论依据。
[Objective]The aim was to screen out bryophytes with strong drought tolerance to use in urban three-dimensional greening.[Method]We studied the drought tolerance of10mosses collected from Jinggangshan Nature Reserve in Jiangxi Province by measuring the changes of water content and photosynthesis efficiency.[Result]All of the10mosses demonstrated drought resistance after drought stress treatment.In particular,four species,that is Hypnum densirameum,Leucobryum juniperoides,Plagiomnium cuspidatum and Weisia platyphylloides exhibited high tolerance to drought.[Conclusion]The results provide theoretical basis for developing the scale production and application in urban greening of bryophytes.
