植物生长调节物质对饵料微藻蛋白质和氨基酸的影响

The effect of plant growth and regulation materials on protein and amino acids of algae in bait

在三角褐指藻、牟氏角毛藻、湛江等鞭藻的f/2培养液中分别添加植物生长调节物质三十烷醇(TA)、6-糠基腺嘌呤(6 FA)和生长素(2,4 D),在指数生长后期采收微藻,测定三种微藻的蛋白质和氨基酸含量。结果表明,分别添加0.1μg/LTA、0.05μg/L6-FA、0.05μg/L2,4-D能够极显著提高三角褐指藻的蛋白质及必需氨基酸的含量,分别添加0.1μg/LTA、0.25μg/L6-FA、0.05μg/L2,4-D能够显著或极显著提高牟氏角毛藻的蛋白质及必需氨基酸的含量,而三种植物生长调节物质使湛江等鞭藻的蛋白质及必需氨基酸的含量显著减少。

In the f/2 foster liquid of Phaeodactylum tricornutum, Chaetoceros muelleri Lemmermann and Isochrysis zhanjiangensis Hu & Lui sp.nov we added separately ITriacontanol(TA), 6Furfurylaminopurine (6FA) and 2,4Dichlorophenoxyacetic acid (2,4D). At the later stage in index, we gathered microalgae and determine the content of protein and amino acid. The result shows, separately added 0.1μg/L TA, 0.05μg/L 6FA, 0.05μg/L 2,4D can extremely notably improve the content of protein and amino in Phaeodactylum tricornutum and 0.1μg/L TA, 0.25μg/L 6FA, 0.05μg/L 2,4D can remarkable or notably improve the content of protein and amino in Chaetoceros muelleri Lemmermann. Three plant growth and regulation materials make Isochrysis zhanjiangensis Hu & Lui sp.nov 's content of protein and amino acid reduce notably.
