【摘要】 目的　本实验通过对不同培养方式和不同培养基发菜的生长情况进行分析 ,以探索发菜人工培养的途径。方法　以不同的培养基以及培养基加营养物质对发菜的藻体、藻丝及细胞在昼夜温度和光照变化中进行培养 ,以观察、分析发菜的生长情况。结果　发菜在液体培养方式下的生长情况好于固体培养方式。结论　水份在发菜的生长繁殖中具有首要作用。此外 ,干燥条件可以影响细菌和真菌对发菜结构的破坏更多还原

【Abstract】 Objective Try to find out an artificial culture method for the growth of Nostoc flagelliforme.Methods Using different culture media with different nutritive elements to culture the filaments, trichome and cells of Nostoc flag-elliforme under different teperaatures and illuminations for 24 h and to analyze the growing status of Nostoc flagelliforme.Results Samples grew better in liquid cultivation than solid cultivation, but there was no significant difference between normal culture medium groups (MS) and nutritive culture medium groups.Conclusion Water plays a very important role in the growth of Nostoc flagelliforme in artificial culture, and the proper condition of temperature and illumination can improve the growth of Nostoc flagelliforme. Dry condition can prevent bacteria and epiphyte to destroy the structure of filaments.更多还原
