【摘要】 <正> 海水密度同紫菜单孢子的放散和附着密切相关。在沿岸河流较多的海区,经常由于淡水流入过多而引起沿岸带海水密度的很大变化。因此对于不同密度的海水同单孢子的放散以及附着关系的了解,直接同单孢子的利用紧密相关。本文阐述了海水密度对单孢子的放散和附着的影响。更多还原

【Abstract】 The present paper deals with the influence of density oi seawater on the discharge and adherence of monospores of P. yezoensis Ueda. Its main results are as follows:1. The monospores can only be discharged under certain density of the seawater ranging from 1.010 to 1.030kg/m3, and the optimum density ior discharging monospores is about 1.020kg/m3.2. The density of seawater required for the adherence of , monospores differs to a certain degree from that required for monospore discharge.更多还原
