Study on Dormancy of Dinoflagellate Cysts

1.在岩手县大船渡湾定期监测塔玛原贡藻和链状原贡藻游动细胞和受精卵的发生，以及由受精卵转化的新休眠包囊的数量，并与环境因子一起监测.线性回归分析未显示任何显着的关系发生之间的Protogonyaulax spp。环境因素3.休眠孢囊在恒温条件下保存时间越长，萌发越同步.在15 ℃恒温条件下，孢囊萌发的潜伏期较短.在恒温条件下，包囊的外观沿着变化。最突出的区别是：孢囊原生质中红色体消失，淀粉粒聚集于孢囊中央，出现褐色色素。叶绿体的形成和原生质膜与胞囊壁的分离是伴随着这些变化的.当原生质内形成叶绿体时，孢囊获得萌发能力。

1. Occurrence of swimming cells and zygotes of Protogonyaulax tamarensis and P. catenella, and number of new resting cysts transformed from the zygotes are monitored regularly together with environmental factors at Ofunato Bay, Iwate Prefecture.2. Linear regression analysis does not show any significant relation between the occurrence of Protogonyaulax spp. and environmental factors.3. Germination of resting cysts is more synchronized when they are kept for longer period at constant temperature.4. Cysts germinate within shorter incubation period when they are kept at 15 oC constantly.5. Appearance of cysts changes along with progression of incubation at constant temperature. Most prominent difference are: disappearance of red body in cyst protoplasm, aggregation of starch granule at the center, occurrence of brownish pigment. Formation of chloroplasts and separation of protoplasm membrane from cyst cell wall follows to these change.6. Cyst obtains germination ability when chloroplasts are formed inside protoplasm.
