Secondary embryo formation was also genotype-dependent and their maturation frequencies varied from 48 to 100%.
      
This result indicates that a specific treatment is required after maturation and before chilling to activate the switch from secondary embryo formation to germination.
      
Primary embryos of all responsive cultivars were harvested directly from ovule cultures; secondary embryo harvests were made from 'Handin' orange ovule cultures and long-term embryogenic callus.
      
When stage II (green globular round matured embryos) and stage III primary embryos (tubular stage embryos) were used, secondary embryo formation was very small and many of these embryos developed into plantlets and some of them even rooted.

This paper reports the free amino acids content of two culture materials in somatic embryogenesis of Comellia chrysantha (HU) Tuyama, one of which has the normal ability of producing secondary embryo(The first), and the other has the poorer ability(The second). Amino acids in the first material is one to five-fold that of in the second, and no Phe, Pro and Tyr were detected in the second material.Based on-mationed results, we utilized Pro, Ser, Phe, Trp and mixed AA to s matic embryogenesis culture.

This paper reports the free amino acids content of two culture materials in somatic embryogenesis of Comellia chrysantha (HU) Tuyama, one of which has the normal ability of producing secondary embryo(The first), and the other has the poorer ability(The second). Amino acids in the first material is one to five-fold that of in the second, and no Phe, Pro and Tyr were detected in the second material.Based on-mationed results, we utilized Pro, Ser, Phe, Trp and mixed AA to s matic embryogenesis culture. The experiment shows that Pro and low con(?)entration(50mM, 100mM)Ser promote the somatic embryogenesis and fresh weight in(?)rease, mixed 50mM Pro, Ser and Phe have the best effect, all of these additional AA except Tyr has a parallel relationship among frequence of embryogenesis, amounts and fresh weight.

本文报道金花茶Camellia chrysantha(HU)Tuyama胚状体培养中,具有正常产生次级胚能力的材料(第一类)和产生次胚能力差的材料(第二类)的游离氨基酸测定结果,以及脯氨酸、丝氨酸对胚状体发生的培养结果。所检出的氨基酸含量,第一类材料为第二类材料的1—5倍;且第二类材料中未能检出脯氨酸,苯丙氨和酪氨酸。在此基础上培养发现:脯氨酸和低浓度(50mmol、100mmol)的丝氨酸促进胚状体发生与鲜重增加,脯氨酸、丝氨酸和苯丙氨酸以50mmol混合使用效果最好,而且除色氨酸外,这些外加氨基酸对胚体形成频率、数目和鲜重的影响之间都有平行关系。

A vital flourescent dye,DiI,was used to label cells at the stage and stage of the chick embryo in order to ascertain the location of the organizer in the blastoderms of these stages.Four types of the of grafts from the organizer area were transplanted into host embryos to see if the epiblast or hypoblast of the organizer area had an ability to induce a secondary embryo.The results showed that the organizer was located in the posterior part of the axis and the secondary embryo was induced only by...

本研究利用活性荧光染料DiI,对鸡胚的期和期胚盘进行标记,以确定组织者的部位。并将组织者区域的细胞移植到宿主胚胎中,验证其诱导次级胚胎的能力。结果表明,期、期胚盘的组织者细胞位于胚盘中轴的后端,其细胞的性质已被决定,能够诱导次级胚胎的发育,本研究结果支持原条的发育与组织者细胞性质不是受下胚层诱导的观点。

recipient goats (crossbred dairy goats)and 76 donor Boer does were used in the study. Treated by synchronization of estrus, the donors ovulated a total of 726 ova, in which there were 387 fertilized ova, making up 53.31% of the total. Among the fertilized ova, there were 353 viable embryos (312 primary embryos and 41 secondary embryos). 105 recipients lambed normally and accounted for 57.07% of the 184 recipients. Two embryos were transferred to each of 97 recipients, 55 of which twinned,...
