【摘要】 于2004年对大连地区北极礁膜M onostroma arcticum的生物学进行了初步研究,并在室内进行了合子采苗、孢子体培养和孢子采苗及幼苗培养等人工育苗试验。结果表明:水温为3℃时,北极礁膜的叶片长度达到16 cm;水温为5℃时,配子放散量达到2.4×108个/g;孢子体在水温低于19℃时生长较快,水温超过22℃时生长几乎停止。孢子体在度过夏季高温期后,当水温降至20℃以下时,开始形成孢子囊;当水温降至15℃时,孢子放散量达到6.1×105个/cm2;孢子附着到苗绳上后经过50 d的室内培养,培育出长度为1 cm的北极礁膜幼苗。更多还原

【Abstract】 Indoor artificial seeding of sea weed Monostroma arcticum Wittrock was conducted through gamete collection,zygote culture,zoospore collection and sporeling rearing.The results showed that the length of thallus was up to 16 cm at 3℃.The released gametes arrived 2.4×10~8 cells/g at 5 ℃.Sporophytes did not grow over 22℃,but grew quickly under 20 ℃.Sporophytes grew into cysts when water temperature was down to 20 ℃ after summer.The released spores reached 6.1×10~5 cells/cm~2 at 15 ℃.The sporelings adhered to net reached 1.0 cm after 50 days’indoor cultivation.更多还原
