因此我们推测CO2加富培养可能改变了鼠尾藻对中肋骨条藻克生作用的方式,由原来的通过分泌克生物质的作用方式变化为细胞直接接触传递的方式。
Accordingly , it was speculated that the action way of allelopathic effect might be changed by CO2 enrichment , which changed from secreting allelopathic substance to direct cell contact transmission .

中肋骨条藻在两种抗生素的暴露下,藻细胞都出现光合作用明显抑制、叶绿素含量显著降低、细胞膜完整性丧失和细胞内ROS积累的现象。
The photosynthesis of algae cells was inhibited , the content of chlorophyll decreased , integrity of cell membrane lost and intracellular ROS increased for both antibiotics exposure .

SK-2的ITS序列与SK-1的相似程度很低,只有51%,但与拟中肋骨条藻的ITS序列相似程度高,为95.5%。
The ITS sequence similarity of SK-2 and SK-1 was very low , showing 51.5 % of identity , but it had very high level of similarity with that of Skeletonema pseudocostatum ( 95.5 % );

在赤潮爆发期间,赤潮原因种高齿状藻和中肋骨条藻发生了明显的演替现象,不同细胞大小的优势种和营养条件的变化是发生物种演替的主要原因。
Cell size and nutrient ratios are the main reasons leading to the shift of red tide species .

与此类似,无论是批次培养的细胞,还是自然群体的模拟培养,中肋骨条藻的生长速率增加总是伴随着细胞链的加长。
Similarly , a positive correlation between growth rate and chain length was observed in S.costatum in batch culture and natural communities in enclosure experiments .
-
而秋季水温较低,浮游植物细胞数量较春季大为减少,中肋骨条藻和柔弱菱形藻对资源的竞争较为缓和,使外界环境变化成为影响优势种变化的主要原因;
In autumn , although nutrient concentrations in the waters were high , phytoplankton density was much lower than that in spring and their competition for resource was mitigated , and the succession of the dominant phytoplankton species was mainly influenced by environmental factors .
