【摘要】 利用逆向照明方法及角膜中和技术,观察了暗适应、明适应和强光适应状态下,家蝇(Musca domestica)复眼感杆中光通量的变化。在强光适应状态下,每个小眼主要呈现一个中心感杆远端的光点像,其外周六个感杆远端光点像模糊不清或消失。利用电子显微镜观察了家蝇复眼小网膜细胞内色素颗粒的移动与适应状态的关系。在强光适应状态下,每个小眼外周六个小网膜细胞No.1～6内绝大部分色素颗粒移动到感杆,而中心两个小网膜细胞No.7～8内色素颗粒并未向感杆移动。但在有些小眼中,小网膜细胞No.7～8内部分色素颗粒移动到感杆。更多还原

【Abstract】 The change of the light flux within the rhabdomeres in the cempound eye of the housefly (Musca domestica) has been observed, by using an antidromic illumination method and optical neutralization technique of the cornea, under dark, bright and high intensity light adapted states. At high intensity light adapted state, a light spot image formed at the one central rhabdomere distal ending appear prominent in every ommatidia, the other light spot images formed at the six peripheral rhabdomere distal endings become indistinct or disappeared. The migration of pigment granules inside the retinula cells in the compound eye of the housefly in relation to adapted states has been observed with the electronmicroscope. At high intensity light adapted state, most of the pigment granules inside retinula cells 1～6 move towards the rhabdomeres, the pigment granules inside therefinula cells 7～8 do not, but, the pigment granules inside the retinula cells 7～8 ofsome ommatidia move towards the rhabdomere.更多还原
