| 摘 要： | 研究了盐肋迫对孔石莼（Ｕｌｖａ ｐｅｒｔｕｓａ）的生理生化效应。结果表明，随盐度增加，孔石莼细胞膜呈透性，组织中可深性粮及脯氨酸含量增加；盐肋迫对藻体膜脂肪酸的影响表现为，经不同盐度肋迫后，多聚不饱和脂肪酸百分比（∑ＰＵＦＡ／∑ＡＦ），平均链长（Ｍ．Ｌ．Ｃ），平均双链数（Ｍ．Ｄ．Ｂ．）均有不同和程度的减少。

| Abstract: | In this paper the biochemical and physiological effects of salinity stress on Ulva purtusa were studied . The result showed that : with salinity increasing, plasmic permeabiliby ,contens of soluble carbohytrate and proline were increased ; After salinity stress , polyunsaturated fatty asids (PUFA) contens, mean double carbon chain length (M.C.L.) and average of mean double bond (M.D.B.) , all were differently reduced . |
