Carpospore output and development in the marine red alga Hydropuntia cornea J. Agardh. were increased by adding polyamines (PAs) (putrescine, spermidine and spermine) singly or in combinations at 10(-9), 10(-6) and 10(-3) M. Cell divisions after spore release and development of apical axis between 17 and 21 days characterized carpospore development. PAs increased carpospore development by promoting cell divisions to form cell masses between day 2 and 3. Morphogenesis to develop apical axes occurred at day 7. Spermine at 10(-6) M and a combination of putrescine 10(-9) M + spermidine 10(-9) M + spermine 10(-9) M gave a higher number of carpospores and enhanced their further development to sporelings.
添加聚胺（PA）（腐胺、亚精胺和精胺）单体或组合在 10（-9）、10（-6）和 10（-3）M 时，可增加海洋红藻 Hydropuntia cornea J. Agardh 的果孢子产量和发育。果孢子释放后细胞分裂和 17 至 21 天之间顶端轴的发育特征是果孢子发育。PA 通过促进细胞分裂在第 2 天至第 3 天之间形成细胞团来促进果孢子发育。在第 7 天发生形态发生以发育顶端轴。10（-6）M 的精胺和 10（-9）M 腐胺+10（-9）M 亚精胺+10（-9）M 精胺的组合产生了更多的果孢子，并促进了它们进一步发育成孢子体。
