| 摘 要： | 探讨了桐花树 (Aegicerascorniculatum)、秋茄 (Kandeliacandel)、角果木 (Ceriopstagal)、海莲 (Bruguierasexangula)和木榄 (Bruguieragymnorrhiza)5种红树植物繁殖体的热值及其动态变化。结果表明 :(1)海南东寨港5种红树植物繁殖体的热值大小不同 ,其中花的热值最高是桐花树 ,为20.423kJ/g,花的热值最低是木榄 ,为19.214kJ/g;果的热值最高是角果木 ,为20.255kJ/g,果的热值最低是木榄 ,为18.582kJ/g;成熟胚轴的热值最高是角果木 ,为19.792kJ/g,成熟胚轴的热值最低是桐花树 ,为16.827kJ/g。 (2)随着纬度的增加 ,桐花树各期繁殖体热值略为提高 ,而秋茄则相反略为降低。 (3)随着繁殖体从花、果至胚轴发育过程 ,热值逐渐降低 ,而单个繁殖体的生物量及其能量贮量则随之提高。

| Abstract: | The paper dealt with the caloric value changes of five mangrove species: Aegiceras corniculatum, Kandelia candel, Ceriops tagal, Bruguiera sexangula and Bruguiera gymnorrhiza. The results are shown as follows: (1) There were differences in the caloric values of the propagules of the five mangrove species at Dongzhai Harbor in Hainan Province of China, the hightest caloric value of flowers was Ceriops tagal(20.423 kJ/g), and the lowest was Bruguiera gymnorrhiza (19.214 kJ/g); the highest of the fruits was Ceriops tagal(20.225 kJ/g), and the lowest was Bruguiera gymnorrhiza(18.582 kJ/g); the highest of mature hypocotyls, the highest was Ceriops tagal(19.792 kJ/g), and the lowest was Aegiceras corniculatum(16.827 kJ/g). (2)With the increase in latitude, the caloric value of the propagules of Aegiceras corniculatum at different developmental stages increased slightly, but decreased for Kandelia candel. (3) With the development of propagule from flower, fruit to hypocotyl, the caloric value decreased gradually, but the biomass and energy storage increased. |
