本文以典型的泌盐红树植物桐花树（Aegicerascorniculatum）和非泌盐红树植物秋茄（Kandeliacandel）或木榄（Bruguieragymnorrhiza）为材料，通过气体交换分析技术、原生质体分离、荧光探针导入及放射性同位素等手段和方法，研究不同盐度对两类红树植物光合速率、蒸腾速率及细胞信号物质如过氧化氢（H2O2）含量、胞内自由钙离子浓度（Ca2+i）及环磷酸腺苷（cAMP）含量的影响，主要实验结果如下： 1 盐度对秋茄胚轴的出叶率及胚轴的总根长影响较大，都是10‰盐度处最大，而对出根总数及出根率几乎没什么影响。 2 盐度不同培养天数对秋茄和桐花树幼苗光合速率的影...The salt-secreting mangrove, Aegiceras corniculatum and non-salt-secreting mangrove, Kandelia candel or Bruguiera gymnorrhiza were cultivated in sand with various salinities (0‰,10‰,20‰,30‰,40‰, 50‰). This paper studied the responses of photosynthetic rate, transpiration rate and some signal molecules such as H2O2, Ca2+ and cAMP to different salinities by using the methods such as gas exchange te...学位：理学硕士院系专业：生命科学学院生物学系_植物学学号：19992601
