研究了5种植物光合作用后有机碳的释放量。2种底栖海洋大型植物(Thalassia teStudum、Diplan thera wright tii、Acanthophora spicifera、Chdria dasyPhylla和Dictyota dihotoma)和1个sp.属于远洋大型海洋植物(马尾藻)。释药速率在0.006-0.053 mg Cg-1h-1之间。释药百分数为1.1-3.8%。种子植物的释放量略低于藻类。对异养生物利用释放产物能力的研究表明，释放的有机碳有20%-30%在2 h内被同化。
The amount of photoassimilated C released as dissolved organic C was investigated for 5 spp. of benthic marine macrophytes (Thalassia testudinum, Diplanthera wrightii, Acanthophora spicifera, Chondria dasyphylla and Dictyota dichotoma) and 1 sp. of pelagic marine macrophyte (Sargassum natans). Release rates ranged between 0.006-0.053 mg C g-1 h-1. Percent release values ranged from 1.1-3.8%. Spermatophytes had slightly lower percent release values than algae. Investigations performed on the ability of release products to be utilized by heterotrophic organisms showed that 20-30% of the released organic C was assimilated within a 2 h period.
