鹽脅迫下幼苗單株葉面積下降的程度大於光合速率的降低，葉面積的減小是導致減產的主要原因；木欖幼苗各組分中的離子濃度以及含量隨栽培時間而變化；栽培初期剛萌根時，幼苗原胚軸中的離子滲漏到培養液中；此後隨著根系的發育以及芽的生長，幼苗轉為從培養液中吸收離子，並以吸收na 、 cl離子為主。Following the embryonic stage of development

幹細胞因子是近年來發現的一種多功能細胞因子。近年來研究發現，幹細胞因子（ stemcellfactor ， scf ）及其受體對胚胎期及成年後神經系統生長發育起調控作用，但其作用機制尚不明了。The postembryonic development of rana chensinensis
中國林蛙胚胎後期發育觀察Using anatomical method, the gonadal development in postembryonic period of rana chensinensis, which had been migrated from northeast china, is studied
摘要採用解剖學方法，對南移后的中國林蛙胚胎後期性腺發育進行了觀察。The results showed that the gonadal development in postembryonic period of rana chensinensis was well - balanced, and the environment of guangdong is adapted to the gonadal development

不同溫度對花背蟾蜍後期胚胎發育的影響Although earlier attempts at retina transplantation using embryonic stem cells failed, the researchers say that by using stem cells at a later stage of development, they were able to repair damaged retinas in the mice
盡管以前嘗試使用胚胎幹細胞進行視網膜移植失敗了，研究人員稱通過使用發育後期的幹細胞，他們修復了小鼠受損的視網膜。“ we worked on the theory that cells at a later stage of development might have a higher probability of success upon transplantation ” says researcher robin ali of the university college london institute of ophthalmology in a news release
盡管以前嘗試使用胚胎幹細胞進行視網膜移植失敗了，研究人員稱通過使用發育後期的幹細胞，他們修復了小鼠受損的視網膜。There was no significant difference between the fusion rates of reconstructed embryos. the cleavage rate of embryos reconstructed with c57bl / 6j oocytes was significant high than that of kunming albino, but the former only developed to 4 - cell stage ; the later could develop to blastocyts. it is implied that the oocytes of inbred mouse cannot support the long - term development of kunming es cell
兩種重構胚的融合率之間沒有顯著差異（ p 0 . 05 ） ， c57bl 6j重構胚的卵裂率（ 60 . 5 ）明顯高於昆明白小鼠（ 33 . 7 ） ，但是前者只發育到4細胞期，而後者可以發育到桑椹期和囊胚期（ 2 . 3 ） 。Ss - ir cells, 5 - ht - ir cells, pp - ir cells, tgf p 1 - ir cells and sp - ir cells were found in the esophagus, the stomach and the duodenum of alligator sinensis embryos
在胚胎發育後期，消化道中以胃的內分泌細胞數量和種類最多，也是內分泌調控最重要的部位，其次是十二指腸。A diploid - dependent regulatory apparatus was proposed by prof. luo et al to regulate gene expression. the haploid condition results in obstruction of gene expression and abnormal development because the diploid - dependent regulatory apparatus will regulate gene expression in the haploid embryos according to the same rule as in the diploid embryos. to study the difference at the protein expression level of the embryos of haploid and diploid in development and to identify the important proteins associated with the embryonic development, we extracted the total proteins of both the gynogenetic haploid and diploid embryos of goldfish in the same eye formation stages ( divided into the substages of he - 1 and de - 1, he - 2 and de - 2, he - 3 and d e ~ 3 respectively )
為了研究在金魚雌核發育單倍體和二倍體胚胎發育過程中的蛋白質表達水平的差異，並鑒定一些與發育相關的重要蛋白質，我們以遺傳背景一致的金魚雌核發育單倍體和正常二倍體的相應眼睛形成的發育階段的胚胎為材料（ 3個時期，分別為he - 1和de - 1 ， he - 2和de - 2 ， he - 3和de - 3 ） ，然後提取胚胎的全蛋白，用二維聚丙烯酰胺凝膠電泳的方法進行蛋白質點的分離，獲得了質量較好的凝膠圖譜，結果顯示大部分蛋白質點分佈在ph5 - 10 ，相對分子質量在10000 - 50000da 。The postembryonic development of rana chensinensis which had been moved to south china were first studied in this paper
摘要首次對中國林蛙在華南地區的胚胎後期發育進行觀察研究。The results showed that the environment of south china adapt to postembryonic development of the rana chensinensis and the higher temperature had no effects on the growth but it accelerated the embryonic development speed
