摘要:
以培养盐京九号水稻幼苗20 d的种植水配置培养液,培养铜绿微囊藻(Microcystis aeruginqsa),追踪测定微囊藻生长量、藻细胞水溶性蛋白含量、超氧化物岐化酶(SOD)活性、叶绿素含量等相关生理生化指标的变化,研究水稻种植水对铜绿微囊藻生长的抑制作用及其机制.实验结果显示,藻细胞生长量和叶绿素含量显著降低;可溶性蛋白含量和SOD酶活性呈先升高后急剧下降的趋势.对水稻种植水抑藻物质作初步分离和鉴定,表明乙醚萃取液中有机酸和酚类组分抑藻效果明显.对有机酸组分进一步做GC/MS分析鉴定,可确定其中
Abstract:
The rice cu lture wa ter ( RCW ) from 20 day. s seed ing s o fOryza sa tiva L. Yanjing 9 w as used to study its inh ibito ry e ffect on the g row th ofM icrocystis aerugino sa and its inh ib itory m echan ism. Results show ed that the grow th o f M. aerugino sa w as obv iously inhib ited by the RCW. The g row th and ch lorophyll contents ofM. aerug inosa decreased, and the so luble pro tein contents and SOD ac tiv ity increased firstly and decreased as the trea tm en t went on. Further resu lts abou t the pur ification and identification of the substances w ith the a lgae- inhib iting effects show ed that the inh ibitory e ffects of o rganic ac id and pheno lic com pounds from the ether ex tracts w ere prom inent, and tr idecano ic acid-12-m ethy,l hex adecano ic ac id and octadecano ic acid w ere identified from its organ ic ac id com ponen ts by the GC /M S.
