摘要
1999年,海南东寨港保护区从墨西哥成功引种拉关木(Laguncularia racemosa),2002年开花结果后,再次引种到广东电白、福建莆田等地,长势良好,均已开花结果,东寨港10年生植株平均高8.9 m。种子千粒重427～476 g,发芽率为90.6%～96.2%;拉关木抗寒性仅次于秋茄,与桐花树、白骨壤相当;抗盐能力明显优于乡土树种,在我国海水盐度为33‰的海滩上造林长势良好。
Laguncularia racemosa,a mangrove species was successfully introduced from Mexico to Dongzhai Harbor,Hainan,China in 1999,and further to Dianbai of Guangdong,and Putian of Fujian in 2002 by using seeds of the introduced plants in Hainan.These plants had already bloomed.10-year-old plants had average height of 8.9m in Dongzhai Harbor,and germination rate was approximately 90.6% to 96.2%.L.racemosa cold tolerance was similar to Aegiceras corniculatum and Avicennia marina,and slightly inferior to Kandelia obovata.The ability of salt tolerance of L.racemosa was obviously better than the indigenous mangrove species.It could grow very well on the beach with 33‰ salinity in the coastal areas in our country.
