摘　　要：条斑紫菜(Porphyra/Pyropia yezoensis)可以产生单孢子,因其能快速直接萌发成叶状体,所以在生产上具有重要的应用价值。本实验主要研究了采样的潮汐周期和地理群体对条斑紫菜叶状体产生单孢子的影响,发现不同采样时间所造成的环境温度变化和潮汐的变化(即节律性的干出)以及不同采样地点所代表的遗传多样性都对单孢子的放散有显著影响。Porphyra/Pyropia yezoensis is able to produce monospores which have a great value on Porphyra industry because they can germinate into thalli directly and quickly.This experiment studied the effects of sampling tide cycle and spot on monospore production from the blade of P.yezoensis.The results showed that both factors have apparent influences.Different sampling tide cycle causes different environmental temperatures as well as different tide heights,which can also be treated as the rhythm of dry-out for Porphyra blades.In addition,different sampling spots represented the genetic diversity of Porphyra geographical populations.
