Basic studies on the processes of reproduction and colony formation in corals.

1. 研究了束状银河菌落多晶体生长速率和其他方面的生长情况。此外，还对该物种与Porites (Synaraea) rus和Pocillopora damicornis的生殖过程进行了分析。2 .采用透射电镜和扫描电镜对达美角Pocillopora damicornis新结息肉进行了研究，并对软组织和骨骼的微观结构进行了分析，特别参考了碳酸钙结晶的初始阶段。研究了巨齿鳄再生骨架的碳酸钙结晶过程，并证实其与正常骨架形成过程相似。此外，还研究了从藻酸纲和硬核纲珊瑚中获得的钙结合物质的钙结合能力，并取得了积极的结果。利用扫描电镜对真菌茎盘的脱落过程进行了研究，发现脱落部位的晶体向粉末转变是导致脱落的原因，而脱落可能是由钙母细胞上皮组织产酸引起的。同时研究了游离过程中机械强度的变化。研究了砂叶和束状星系两种植物的受精、胚胎发生和幼虫的变态。本文研究了束状星系触手内线虫囊在正常向清扫型转变过程中的变化。被囊细长、线轴较长的线虫囊转变为被囊较粗、线轴较短、较暗的线虫囊，拟纳入b-横纹肌群。

1. Growth rates and other aspects of polypal growth in the colonies of Galaxea fascicularis were studied. In addition, reproductive processes of this species, Porites (Synaraea) rus and Pocillopora damicornis were elucidated.2. Newly settled polyps of Pocillopora damicornis were studied by transmittance and scanning electron microscope and the microstructure of both soft tissues and skeleton were analyzed with special reference to the initial stages of calcium carbonate crystallization.3. Calcium carbonate crystallization processes of the regenerating skeletons of Acropora hebes were examined and elucidated to parallel the normal skeleton formation processes. In addition, calcium binding capacity of calcium binding substance obtained from alcyonacean and scleractinian corals was studied and positive results were obtained.4. Processes of detachment of discs from stalks of Fungia fungites was studied with scanning electron microscope and found that crystal to powder transformation at the detaching site was found reponsible for detachment, which in turn was probably induced by acid production of calicoblastic epithelial tissues. Changes in mechanical strength in the course of detachment was studied also.5. Fertilization, embryogenesis and metamorphosis of the larvae of Lobophytum crassum and Galaxea fascicularis were studied.6. Transformation of nematocysts in the tentacles of Galaxea fascicularis during the course of changes from the normal to sweeper were studied. Nematocysts with slender capsules and long shafts of threads transformed into those with fat capsule and short and obsure shaft, which were proposed to be included in b-rhabdoid group.
