摘要：在海南、深圳红树林区引种孟加拉国优良速生树种无瓣海桑，均已开花结果。种子千粒重为１４．４１～１４．８８ｇ，发芽率为９０％～９６％，１年生苗高为１．５ｍ左右。海南无瓣海桑５年生平均高为９．２ｍ，平均胸径为１２．９ｃｍ，分别高出本地优势种海桑３９．４％和２６．５％，差异极显著。深圳２．５年生留圃幼树平均高为５．３ｍ，优势树高为６．２ｍ，平均胸径为４．７ｃｍ。种植１年后的幼林平均高为２．１ｍ，平均地径６．３ｃｍ。对土壤、潮带及海水盐度适应性同海桑相似，抗寒性明显优于海桑属乡土种类，具有显著的引种潜力和利用前景。
Superior and fast growing mangrove tree species Sonneratia apetala Buch Ham was introduced to Hainan Island and Shenzhen mangrove zone(19°38′～22°32′N) of China in 1985 from Sundarban mangrove zone,southwest of Bangladesh and has normally blossomed and borne fruit.The weight of one thousand seed is 14.41～14.88 g,seed germination percentage 90～96,and one year old seedlings more or less than 1.5 m.Growing in adaptable habitat in Hainan mangrove zone,the mean height of five year old trees is 9.2 m,the mean DBH of that 12.9 cm,39.4% and 26.5% higher than that of indigenous dominant tree species S.caseolaris (L) Engl respectively;the mean height of 2.5 year old young trees is 5.3 m and that of best growing tree is 6.2 m at Shenzhen mangrove bay in Guangdong Province.Its cold resistance is obviously stronger than that of all indigenous species of the same genus distributing in China and it has the similar adaptability as them to mudflat,tidebelt height and salinity.So S.apetala has remarkable potentiality and promising prospect in China.
