| 摘 要： | 以孔石莼(Ulva pertusa)为试验材料,研究了连续性干出对其生长和生化组成的影响.结果表明:与对照组(0 h)相比,短时间的连续性干出促进孔石莼生长,表现在特定生长率( SGR)升高、叶绿素a含量上升；随着连续性干出时间延长,孔石莼SGR、叶绿素a、蛋白质含量下降,叶绿素b、可溶性糖含量上升；叶绿素a/b比值变化和可溶性糖含量变化有利于抵抗干出胁迫.

| Abstract: | This study showed that as compared with the control,a short term continuously diurnal desiccation promoted the growth of Ulva pertusa,manifesting in the increase of specific growth rate(SGR) and chlorophyll a content.However,with the prolonged desiccation duration,the SGR and chlorophyll a and protein contents decreased,while the chlorophyll b and soluble sugar contents increased.The changes of chlorophyll a/b and soluble sugar content could benefit the desiccation tolerance of U.pertusa. |
