Abstract
This study investigated the seed priming effects with aqueous extracts from the cyanobacterium Anabaena minutissima (AM) and the brown seaweed Sargassum vulgare (SV) on the growth and nutritional properties of China Rose (CR), Daikon (D), and Sango Red (SR) radish varieties. AM and SV biomasses were chemically analyzed. FTIR spectra of biomasses exhibited functional groups characteristic of amides I and II of proteins in AM and functional groups associated with the pyranose ring of carbohydrates in SV. The extracts differed in total proteins, phycobiliproteins, carbohydrates, chlorophylls, carotenoids, and antioxidant activity. Seed priming with AM and SV particularly increased seed germination (2% in CR), moisture (5% in D with AM), sprout weight (35% with AM), and height (12% with SV). In the elemental analysis of sprouts, Na, Ca, and Mg levels increased variably across all varieties of both extracts. Principal component analysis revealed significant separation among treatments in SR and D varieties, confirming the effectiveness of the seed priming.
本研究调查了用蓝藻小肠藻（AM）和褐藻马尾藻（SV）的水提取物对中国玫瑰（CR）、萝卜（D）和山乡红（SR）萝卜品种的生长和营养特性的种子诱导效应。对 AM 和 SV 生物质进行了化学分析。生物质的傅立叶变换红外光谱显示出 AM 中蛋白质酰胺 I 和 II 的特征官能团，以及 SV 中与碳水化合物吡喃糖环相关的官能团。两种提取物在总蛋白、藻胶蛋白、碳水化合物、叶绿素、类胡萝卜素和抗氧化活性方面存在差异。用 AM 和 SV 给种子打底尤其能提高种子发芽率（CR 为 2%）、水分（D 与 AM 相比为 5%）、萌芽重量（AM 为 35%）和高度（SV 为 12%）。在芽的元素分析中，Na、Ca 和 Mg 的含量在两种提取物的所有品种中都有不同程度的增加。主成分分析表明，SR 和 D 品种的处理之间有明显的差异，这证实了种子引诱的有效性。
