Akinete germination may be a starting point of some akinete-producing cyanobacterial blooms in eutrophic freshwater systems. This study examined germinability of akinete of a cyanobacterium Anabaena circinalis isolated from the sediment of the North Han River (Cheongpyung Dam), Korea, under several ...

휴면포자는 무엇인가? | 남조류 Aanbaen는 불리한 성장환경에서 무성생식 과정을 통해 휴면 기능을 갖는 세포인 휴면포자(akinete) 를 형성한다. 휴면포자는 일시적으로 휴면상태를 나타내며 (Dale, 1983), 다시 성장환경이 좋아지면 발아하여 영양세포로 발전하는 생활사를 가지고 있다. | |
휴면포자발아에 영향을 미칠 수 있는 이화학적 또는 생물학적 작용은 무엇인가? | , 2003). 이러한 환경요인들과 더불어 이화학적 또는 생물학적 작용으로 퇴적물로부터 영양염류의 용출 및 영양염 비율 변화, 용존산소 농도, 염분 농도, 일시적인 퇴적물의 재현탁(resuspension events), 무척추동물에 의한 생물교란(bioturbation) 등이 영향을 미칠 수 있다(Baker and Bellifemine, 2000; Stáhl-Delbanco and Hansson, 2002; Faithfull and Burns, 2006). | |
