通过设置不同盐度、基质的室外培养实验,研究了老鼠簕(AcanthusilicifoliusL.)在不同盐度和基质生境条件下的生长、生理特性及体内总黄酮含量的变化。设计6个盐度水平:0、5、10、15、25和35;5个基质水平:100%海泥+0%砂、70%海泥+30%砂、50%海泥+50%砂、30%海泥+70%砂(V/V)、红壤土,均以盐度5的人工海水进行培养,分别用0%、30%、50%、70%、RS表示。培养365d。分析探讨了盐度、基质对老鼠簕幼苗的生长、生物量分配、光合作用、丙二醛含量(MDA)、游离脯氨酸含量、过氧化氢酶(CAT)、过氧化物酶(POD)、超氧化物歧化酶(SOD)、苯丙氨酸...Acanthus ilicifolius L. seedlings were cultivated out of doors and treated with different levels of salinity and sediments. 6 levels of salinity were 0, 5, 10, 15, 25, 35. 5 levels of sediments were 100% sea mud(0% sandy), 70% sea mud+30% sand(30% sandy), 50% sea mud+50% sand(50% sandy), 30% sea mud+70% sand(70% sandy), red soil(RS). All seedlings in different sediments were treated with same sali...学位:工学硕士院系专业:海洋与环境学院环境科学与工程系_环境工程学号:2005130224
