摘　　要：在全光照条件下培养红树植物桐花树(Aegiceras Corniculatum)3a龄苗1a,以人工海水(盐度8g.kg-1)为对照,研究了淡水种植对桐花树开花结果的影响.结果表明:人工海水组比淡水组提前23d出现花蕾;淡水组的最早始花日期比人工海水组延迟了50d.两种处理下桐花树的花序数随时间的变化呈现出两个生长高峰期,即第一个生长高峰期出现在2010年12月,第二个生长高峰期在2011年4月.在4月份,淡水组的花序数显著多于人工海水组.两种处理的桐花树座果数及其成熟果实的果重、粗度和长度之间均不存在显著差异.试验表明,桐花树在淡水环境里能够正常开花结果.Using artificial seawater （8 g. kg - 1 in salinity） as control treatment, the Aegiceras Corniculatum lugage of three - year - old were cultivated in freshwater with constant - water level under full sun light for one year to inves- tigate the effect of fresh water on the flower bloom of Aegiceras Corniculatum lugage. The results showed that the plants of artificially group first appeared in bud, and the budding date in fresh water treatment was 23 days later than the artificial sea treatment, but the earliest flowering date of former was 50 days later than that of the artificial treatment. With the change over time, the inflorescence number of Aegiceras Corniculatum under the two kinds of different treatment showed two growth peak. The first growth peak appeared in December 2010, and the second growth peak in April 2011. In April, the inflorescence number of freshwater group was significantly more than artifi- cial seawater. There is no significant difference of Fruit - set number between the two kinds of different treatment of Aegiceras Corniculatum, as well as its weight, length and thick degree of mature fruit, the result demonstrated that the Aegiceras corniculatum lugage cultivated in freshwater could not only growth normally, but also could blossom and yield fruit.
