摘要:
真江蓠是我国重要的栽培藻类,具有较高的经济价值、药用价值和生态价值。为了优化真江蓠四分孢子放散、附着、萌发和生长等过程的培养条件,选择温度、光照度和盐度3个环境因子,采用单因素试验研究不同环境因子对真江蓠四分孢子放散和发育的影响。结果显示:温度、光照度和盐度对真江蓠四分孢子放散和发育具有显著影响(P<0.05),当温度为20~25 ℃、光照度为15~60 μmol/(m2·s)、盐度为28‰~36‰时,真江蓠孢子放散量达到最大值2.8~3.3×106个/g;低温(15~25 ℃)、低光[15~60 μmol/(m2·s)]和低盐(24‰~32‰)有利于四分孢子的附着和萌发,真江蓠孢子附着率高于85%,萌发率高于90%;中温(20~25 ℃)、高光[60~100 μmol/(m2·s)]和低盐(24‰~32‰)有利于真江蓠孢子后期(直立体阶段)幼苗的生长发育,线性生长速率最高可达(148.95±4.28) μm/d。研究优化了真江蓠四分孢子放散和培育的条件,为探索真江蓠室内采孢子育苗提供了理论支持。
