Comparison of morphological and epidermal characters of different tropical carrageenophyte species
摘要
Abstract
The external forms and characters of epidermal cells in 12 strains of tropical eucheumatoid species were surveyed by means of optical microscope and electronic scanning microscope in Qingdao laboratory and Lingshui experimental platform during the period of June 2008 to June 2009. The results showed： 1） Different strains showed diverse colors ranging from green, yellow-green, emerald green, olive green, to brown and dark brown. 2） Among all the tested stains, strain 5 had the smallest epidermal cell size, most uniform cell distribution and narrowest intercellular space; on the contrary, strain 8 has the largest cell size, and widest intercellular space. 3） As for submi- croscopic structures, uniform globular protuberances in strain 1, irregular protuberances in strain 2 and 4, dimple-like depressions in strain 2, 6 and 9, brain-like folds in strain 7 and 11, relatively smooth surface in strain 5 and 8, and rugged structure covered by white colloidal substances in stain 12 were displayed. 4） Among all the experi- mental strains, tetraspores were found mainly on the old branches of strain 3, 5, 6 11 and 12, however, no tet- raspores was found in strain 1, 2, and 4. 5） All the tetraspores in each strain were symmetrical. The tetraspores in strain 3, 5, 11 and 12 connected closely in contrast to loosen array in strain 6. 6） The size of tetrasporangium in different strains varied significantly. Strian 6 and strain 5 had the longest and shortest tetrasporangium; respectively, which are about 110 μm and 40μm, different from the tetrasporangiums of strain 3, 11 and 12, which were all about 60 μm. Tetrasporangiums of most strains had a fixed 15 μm width except strain 5, which was about 10 μm.关键词
