According to the mechanism of block of development in vitro culture on early embryo of mammal and in vivo surroundings of early embryo, the paper states that requirement and utilization of nutrients during each cell stage of early embryo of mammal in vitro culture in order to search for in vitro culture condition and method to improve the development rate of blastosphere
摘要從哺乳動物早期胚胎體外培養發育阻斷機理和早期胚胎的體內環境入手，闡述了胚胎體外培養各細胞階段胚胎對營養物質的需求，尋求合理的體外培養條件和方法，以便提高體外胚胎早期的囊胚發育率。Abstract : the early embryo developmental block is a common phenomenon in mammal when embryos are cultured in vitro. many studies of phosphorus, glucose, hypoxanthine and cytoplasmic factors on early embryo developmental block carried out by different methods such as morphology, biochemistry, molecular biology and micromanipulation have been reviewed. the merit and shortcoming were analyzed and the necessity of using simple or components limited media overcoming early embryo developmental block were also reviewed. media that have been shown effective in overcoming early embryo developmental block in mouse, rat, hamster, rabbit, pig, sheep, cattle and monkey were listed
摘要哺乳動物胚胎在體外培養中普遍存在早期發育阻滯的現象.對此，人們用形態學、生物化學、分子生物學、顯微操作等手段開展了磷酸、葡萄糖、次黃嘌呤和細胞質因素對早期胚胎發育阻滯的影響的研究.本文綜合分析了共培養系統的優缺點.說明了採用完全成分已知的培養液對進行有關研究的必要性.列出了有效運用於克服小鼠、大鼠、倉鼠、兔、豬、羊、牛、猴等動物早期胚胎阻滯的成分已知的培養液的名稱。Cotyledon and hypocotyl ' s rate and quamity are the most among these explams, and callus can be obtained in 10 days by cotyledon and hypocotyl. reversely it is difficult to indue callus with root, and the callus from root is lnde and easy to become browning. the calius obtained from leaf grows very slow and does not become browning uniill in 2 or 3 months
銀杏的不同器官和組織都能夠誘導出愈傷組織來，其中，子葉和胚軸10d左右全部愈傷化，誘導速度和誘導率均最高，根則很難誘導，愈傷組織很少，褐化很快；葉片誘導的愈傷組織，生長慢，褐化也慢，在培養基上保持兩三個月而不褐化；胚乳的誘導時間也較長，需要30d左右。Dodecaploid plantlets regenerated from endosperm culture of luotiantianshi persimmon
