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

1.研究了丛枝银杉菌落的生长速度和多倍体生长的其他方面。此外，还对该物种的繁殖过程进行了详细的描述。采用透射法和扫描电子显微镜对刚定植的斑角波纹夜蛾的息肉进行了研究，并结合碳酸钙结晶的初期阶段对软组织和骨骼的微观结构进行了分析。研究并阐明了顶孢霉再生骨骼的碳酸钙结晶过程，以平行于正常的骨骼形成过程。此外，还对青蟹类和珊瑚类钙结合物的钙结合能力进行了研究，取得了积极的结果。用扫描电子显微镜研究了真菌菌柄的脱落过程，发现脱落部位的晶体向粉末的转变是引起脱落的原因，这可能是由钙质母细胞上皮组织的产酸引起的。并对分离过程中机械强度的变化进行了研究。研究了粗枝莲和丛枝银杉幼虫的受精、胚胎发生和变态过程。研究了丛枝银河猴触角内线囊在由正常向扫地转变的过程中的变化。包膜细长、线轴较长的线囊转变为具有脂肪包膜和短而闭塞的线囊，建议将其归入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.
