摘要
将红树植物正红树（Rhizophora apiculata）、海莲（Bruguiera sexangula）和木榄（B．gymnorhiza）从海南岛引种到珠海淇澳·担杆岛省级自然保护区，苗期生长正常。1a生的正红树、海莲和木榄平均苗高分别为45．3cm、28．7cm和56．7cm，平均地径分别为1．34cm、0．64cm和1．60cm，保存率分别为40．9％、59．5％和70．5％。3种红树植物苗期抗寒性大小依次为木榄〉海莲〉正红树。正红树、海莲和木榄3种红树植物能基本适应引种地的自然条件，对其生长发育特性尚需进行跟踪调查。
Three mangrove tree species Rhizophora apiculata, Bruguiera sexangula and B. gymnorhiza were introduced from Hainan Island to Qi＇ao-Dangan Provincial Nature Reserve. All species showed better growth during the seedling stage. At one-year-old, the average seedling heights ofR. apiculata, B. sexangula and B. gymnorhiza were 45.3 cm,28.7 cm and 56.7 cm, respectively, the average seedling diameters were 1.34 cm,0.64 cm and 1.60 cm, respectively, and the preserving rates were 40.9%, 59.5% and 70.5%,respectively. Through the comprehensive evaluation, the cold resistance of three species ranked in the order ofB. gymnorhiza 〉 B. sexangula 〉 R. apiculata. These three mangrove species can adapt to natural conditions of the introduced area, but their growth and development properties need further survey.
