| 摘 要： | 为促进蜈蚣藻属 (Grateloupia)藻类的开发利用，为其食用和加工提供参考，该研究于2018年1—4月间每月１次对广东汕头南澳和福建东山浮筏上的蜈蚣藻属种类组成、生物量、生长环境及不同种类不同生长时期的口感进行了调查。结果显示，调查点的水温和水流速度分别为19~23 ℃ 和 0.039~0.985 m·s−1，福建东山的流速较汕头南澳的大。采用培养观察形态变化、藻体切片以及rbcL序列分析相结合的方法判断这两处浮筏上的蜈蚣藻属为披针形蜈蚣藻 (G. lanceolata)、带形蜈蚣藻 (G. turuturu)、台湾蜈蚣藻 (G. taiwanensis)、肉质蜈蚣藻 (G. carnosa)、舌状蜈蚣藻 (G. livida)、海门蜈蚣藻 (G. haimensis)、长枝蜈蚣藻 (G. prolongata)和稀疏蜈蚣藻 (G. sparsa)。披针形蜈蚣藻和带形蜈蚣藻为优势种，两者最高生物量分别达到901.26 g·m−1和352.9 g·m−1。水流速度较大地方生长的披针形蜈蚣藻藻体较长(可达142 cm)。长枝蜈蚣藻和带形蜈蚣藻口感最差；披针形蜈蚣藻、舌状蜈蚣藻的口感最好，这2种仅在4月质地变硬时口感略差。披针形蜈蚣藻生物量多、藻体大且食用口感好，是值得加工为海洋蔬菜的优良种类。

| Abstract: | In order to promote the development and utilization of Grateloupia and provide reference for its food and processing, we investigated the species composition, biomass, growth environment and mouthfeel of Grateloupia on floating rafts in Nan'ao, Shantou, Guangdong Province and Dongshan, Fujian Province once a month from January to April 2018. The results show that the water velocity and temperature were 0.039−0.985 m·s–1 and 19−23 ℃, respectively, and the water velocity in Dongshan was greater than that in Nan'ao. By morphology, cross-section and rbcL sequence analyses of the samples collected from the floating raft, we found eight Grateloupia species (G.lanceolata, G. turuturu, G.taiwanensis, G.carnosa, G.livida, G. haimensis, G. prolongata and G. sparsa). The dominant species were G. lanceolata and G. turuturu whose highest biomass were 901.26 g·m–1 and 352.9 g·m–1, respectively. G. lanceolata that grew with higher water velocity had longer body length that could reach 142 cm. The mouthfeel of G. turuturu and G. prolongata was the worst but that of G. lanceolata and G. livida was the best. G. lanceolata and G. livida had better mouthfeel in January to March than in April. It is worth developing G. lanceolata as marine vegetable for its bigger biomass, size and its better mouthfeel. |
