The experiment studied the effects of applying different amount of B and Zn to peanuts growth, development and yield. The results showed that by supplying rational micro-fertilizer of Boron and zinc, the growth and development of the first pair cotyledonary branch, root nodules leaves and pods could be promoted, the yield was significantly increased on the basis of supplying rational Nitrogen, Phosphorus and Potassium. In this experiment, supplying Boron 7.5 kg/hm^2 and 11.25 kg/hm^2 could increase by 6.87% and 8.19% in comparison with CK, supplying Zinc 7.5 kg/hm^2 and 11.25 kg/hm^2 could increase by 7.17% and 5.20% in comparison with CK.

采用大田试验研究了增施不同量硼、锌微肥对花生生长发育和产量的影响，结果表明，在合理施用氮、磷、钾肥的基础上，适量配合施用硼、锌微肥可以明显促进花生一生的生长发育，增加花生第一对侧枝长、单株根瘤、叶片和荚果数等，显著提高花生产量，其中增施硼肥7.5和11.25 kg/hm^2的处理比较对照分别增产6.87和8.19%，增施锌肥7.5和11.25 kg/hm^2的处理比较对照分别增产7.17和5.20%。

The expression profiles analysis of 25 genes belonging to 8 types in different development periods of Y35 somatic embry showed, genes involved in transcription, signal transduction, cell fate, substance transport, cell and development regulation were active at early and middle stages of somatic embryogenesis, while at the stage of cotyledonary embryo maturation, the high level-expressed genes were mainly those related to storage protein, maturation and defense.

通过半定量和Real-Time PCR技术，对WRKY和MAPKK等8类25个差异表达基因在Y35体细胞胚不同发育时期的表达分析显示，转录、信号转导、细胞生长分裂、细胞命运、物质转运和多数发育调节相关基因在体细胞胚胎发生的早期或中期比较活跃，而进入子叶胚成熟后期则主要是储藏蛋白、成熟和防御相关基因大量表达。

The results were showed that somatic embryos can be directly re-induced from cotyledonary, which was cultured on MS medium supplemented with ZTO.5-2 mg/L, BA 1mg/L and NAA 0.2mg/L, and the induction rate was over 80%.

结果表明，MS+ZT 0.5～2mg／L+BA 1mg／L+IAA 0.2mg／L培养基可直接诱导体胚发生，诱导率超过80％；MS+BA 2mg／L+NAA 0.2 mg／L或MS+TDZ 0.01 mg／L+NAA 0.2 mg／L培养基可直接分化不定芽，出芽诱导率分别为88％、100％。

Cotyledonary node explants were prepared from 5-7 day old seedlings, infected and co-cultivated with Agrobacterium tumefaciens. Resistant adventitious buds emerged after 4 weeks on selective medium.

从发芽5-7天的大豆无菌苗切取子叶节外植体，经农杆菌感染和共培养后，在选择培养基上4周左右出现抗性不定芽。

The high frequency plant regeneration system of Medicago truncatula with cotyledonary-node explants was developed through direct shoot organogenesis.

通过直接的芽器官发生途径，建立了蒺藜苜蓿Medicago truncatula子叶节外植体的高频植株再生体系。

After that, the apical cell divided vertically respectively to form 2-celled, 4-celled, and multicellular proembryos and developed into globular embryoid, heart-shaped embryoid, torpedo embryoid,cotyledonary embryoid.

花药很容易诱导成球形胚或心形胚，但大多数胚状体发育停留在球形胚或心形胚阶段，不能形成正常胚，而成为畸形胚，只有少量发育成正常胚，最终发育成正常植株。

When cultured on the medium with different auxin , root segments could elongate and branch, and the addition of 1mg/l IBA into the medium was the most suitable for long-term root culture. Calli could be induced from root explants in the presence of 2, 4-D and when transferred onto E medium, they transformed further into embryonic calli which could develop into normal plants through the stages of globular-embryo, heart-shaped embryo, torpedo-shaped embryo, cotyledonary embryo.

培养基中添加生长激素（IAA，IBA，NAA）能够诱导无菌苗根切段的生长和分枝形成；而1mg／l IBA的存在，最适合于根的长期离体培养。2，4-D的存在能够诱导根外植体脱分化形成愈伤组织，愈伤组织转移至E型分化培养基能够转变成胚性愈伤组织，并进一步经球形胚、心形胚、鱼雷形胚、子叶形胚发育成正常植株。
