摘要
三疣梭子蟹(Portunus tritubereulatus)经过30 min暗适应后,在不同波长的红光(750 nm),黄光(580 nm),绿光(560 nm),蓝光(400 nm)下,其光感受器形态和超微结构随不同波长光的适应而发生变化。在红光下感杆束直径大,微绒毛排列最整齐,内质网、线粒体等胞器较多,色素颗粒分布均匀,膜下储泡囊小;在蓝光下感杆束直径最小,微绒毛最凌乱,多囊体、板膜体、膜下储泡囊等胞器较多,色素颗粒位于细胞核周围。
The fine structure of compound eye in Portunus tritubereulatus under different wavelength lights adaptation was studied with electron microscopy. The Portunus tritubereulatus were trained in a darkroom for 30 minutes and they were given the lights of different wavelength (red 750 nm, yellow 580 nm, green 560 nm, blue 400 nm). The result showed that fine structures varied with different wavelength lights. Under red light, the diameter of rhabdom was biggest, the microsvilli was orderly. There were more endoplasmic reticulum and mitochondria in the cell. The pigment granules were distributed everywhere in the cytoplasm. The dimension of perirhabdomal vacuoles was small. Under blue light, the diameter of rhabdom was smallest, the microsvilli was messy. There were more lamellar bodies, lysosomes and perirhabdomal vacuoles in the cell. The pigment granules were distributed around nucleolus.
