胚胎物质利用论文文献综述

吴旭干,刘智俊,姚桂桂,成永旭,杨筱珍[1](2009)在《叁疣梭子蟹胚胎发育过程中肝胰腺的发生与卵黄物质利用的关系》一文中研究指出通过对叁疣梭子蟹胚胎进行连续采样和组织切片,系统研究了叁疣梭子蟹胚胎发育过程中卵黄囊和肝胰腺的发生与卵黄物质利用的关系。结果表明:(1)叁疣梭子蟹胚胎的卵黄岛和卵黄囊结构分别出现在原肠期和无节幼体期,胚胎从原肠期至卵内第一期溞状幼体期,始终存在卵黄岛结构,且卵黄岛中的卵黄物质不断被分解和利用.(2)卵内第二期溞状幼体后,卵黄囊分为两个区域,卵黄囊壁中出现肝胰腺细胞(柱状上皮细胞),此时肝胰腺前体已开始形成,卵黄岛开始融合.(3)卵内第叁期溞状幼体阶段,卵黄囊发育成一双肝胰腺,由于肝胰腺中的卵黄物质互相融合,卵黄岛结构消失。此阶段胚胎对卵黄物质的利用加快,卵黄物质中存在许多空泡状结构;(4)胚胎发育进入孵化前期后,肝胰腺腔内的卵黄物质极少,而初孵溞状幼体肝胰腺腔内卵黄物质已完全消失,肝胰腺为一对囊状结构。这些结果表明在叁疣梭子蟹胚胎发育从原肠期到孵化前的过程中,卵黄岛和肝胰腺细胞对于卵黄物质分解和利用起着十分重要的作用。(本文来源于《动物学研究》期刊2009年04期)

吴义莲,许雪峰,吴霖生,张建龙[2](2006)在《丽斑麻蜥胚胎物质和能量的利用及孵出幼体的特征》一文中研究指出We studied the embryonic use of material and energy during incubation and hatchling traits in the lacertid lizards Eremias argus, which were collected from a mountain population in Langyashan, Chuzhou, eastern China in April, 2005. We randomly selected one egg from eleven clutches, opened and separated them into shell and contents, the other eggs were incubated at naturally fluctuating temperature (varying from 14.0 to 37.0℃) using wet vermiculite as the incubation substrate, of which the moisture was kept at -12 kPa water potential. The incubation length of first clutches and second clutches averaged 37.5 d and 33.0 d, respectively. The wet mass of eggs increased for absorbing moisture while incubating, but no significant difference of the final wet mass was founded between first clutches and second clutches. Fluctuating temperature significantly affected Fat body dry mass, but it did not affect hatching success, sex ratio, snout-vent length, tail length, body wet mass, body dry mass, carcass dry mass and residual yolk dry mass of hatchlings. Fat body dry mass from higher fluctuating temperature was greater than did that from lower fluctuating temperature. Incubation temperature affected some norphological traits of hatchlings, with hatchlings from higher temperature having larger hindleg length and tympanum length than did those from lower temperature. Embryo from higher temperature used much calcium than did that from lower temperature. During incubation, approximately 57.5% of dry material, 27.8% of non-polar lipids and 47.4% of energy in the yolk of freshly laid egg was transferred to the hatchling. There was not significant clutch variation of embryonic use of material and energy and hatchling traits in Eremias argus.(本文来源于《动物学报》期刊2006年06期)

杜卫国,计翔[3](2001)在《孵化温度对中华鳖胚胎物质和能量利用的影响》一文中研究指出用多重温度组合 [7个恒温 ( 2 3、 2 4、 2 7、 2 8、 3 0、 3 3和 3 4℃ )和 1个波动温度 ( 2 2 3~ 3 2 8℃ ) ]孵化中华鳖 (Pelodiscussinensis)卵 ,检测温度对胚胎利用卵内物质和能量的影响。卵在波动温度和温和温度下( 2 7℃和 2 8℃ )孵化有较高的干物质、脂肪和能量转化率 ,孵出幼体因而含有较多的无机物 ,幼体躯干和脂肪体含有较高的能量。卵在极端高温 ( 3 4℃和 3 3℃ )或极端低温 ( 2 3℃ )下孵化物质和能量转化率较低 ,使得孵出幼体中无机物较少 ,幼体躯干和脂肪体中含能量较低。孵化温度显着影响中华鳖孵出幼体内的能量分配 :2 7℃和 2 8℃孵出幼体含能量较高且相似 ,但 2 7℃孵出幼体剩余卵黄能量小于 2 8℃孵出幼体 ;3 4℃和 2 3℃孵出幼体含能量较低且相似 ,但 2 3℃孵出幼体剩余卵黄能量大于 3 4℃孵出幼体。波动温度拓宽存活孵化温度范围(本文来源于《动物学报》期刊2001年05期)
