Unlike the axe, the blade of the adze is set at right angles to the handle, so that, in use, the cutting edge is horizontal rather than vertical.

不同的是斧头，锛子叶片的设置成直角的处理，因此在使用中的，最前沿的水平，而不是垂直的。

In this article, the domain structure of LBD genes, classes of LBD genes in model plants of monocotyledon or dicot, expression model, mutation phenotypes from loss of function or gain of function, and its relationship to other gene families were reviewed. Furthermore, the redundancy character of LBD genes, basic candidate function shared by LOB domain, and potential molecular mechanism of LBD genes interacting with other genes also were discussed.

本文对LBD基因的结构域特征、在单／双子叶模式植物中的分类、表达特点、己克隆LBD基因的功能及与其它基因或基因家族间的相互作用关系进行了综述，并对LBD基因在高等植物中的功能冗余特性、LOB结构域可能所具有的基本功能和LBD基因与其它基因相互作用的分子机制进行了探讨。

Western blot and the immunoblot results indicate that the antibodies not only can react with silicon-binding proteins of rice, but also can cross react with the proteins of other silicon-accumulated graminaceous plants, while it does not react with the proteins of non-silicon accumulated dicotyledonous plants and BSA. These findings indicate that the homologous proteins of SBP117 are widely existed in the graminaceous plants.

蛋白质印迹和免疫印迹检测表明，SBP117的抗体不仅能识别水稻硅结合蛋白，而且与其他累积硅的禾本科植物中提取的硅结合蛋白有交叉反应，但它不识别不累积硅的双子叶植物番茄叶中的蛋白质以及牛血清蛋白，说明与SBP117同源的硅结合蛋白广泛存在于禾本科植物之中。

Immunoblot results indicate the antibody can also cross react with the proteins of other silica-accumulated graminaceous plants, while it does not react with the proteins of dicotyledonous plants. These findings indicate that the homologous proteins of SBP117 are widely existed in the graminaceous plantss. This indicated silica accumulated in higher plants posses the character of systematic development.

免疫印迹检测表明此抗体还能与其它累积硅的禾本科植物硅体中的蛋白发生交叉反应，但不能与双子叶植物蛋白反应，这说明与SBP117相似的硅结合蛋白广泛存在于积累硅的禾本科植物之中，硅在高等植物中的积累具有系统发育上的特征。

Efficient usage of the main storage material in megagametophyte before it falls off from seedling is important for seed germination of Pinus edulis Engelm.. We examined and compared lipid usage in both megagametophyte and cotyledon with electromicroscopic technique, the length, dry weight, starch content and FBPase activities of each part of the seedling were measured and compared.

采用电镜技术观察了黑暗中萌发中食松子叶和提供营养的雌配子体中脂肪体和与脂肪利用有关的乙醛酸循环体的变化，测量比较了子叶、下胚轴、根的长度、干重、淀粉含量，以及果糖1，6二磷酸酶的活性变化，对贮藏物质脂类、淀粉的利用及与生长的关系进行了分析。

Seeds ovoid to reniform; seed coat with thick inner layer of dense black sclerenchyma and spongy outer layer bounded externally by a shiny black pellicle; endosperm copious; embryo straight or slightly bent; cotyledons ovate to elliptic, flattened; hypocotyl superior.

种子卵球形到肾形；种子涂上厚内部层紧密的黑色的sclerenchyma 和海绵状的外部层通过一发亮的黑色的表膜外部束；胚乳丰富；胚稍弯曲的直的或；子叶卵形到椭圆形，扁平；下胚轴上位。

We studied the optimum medium and hormone combination of callus induction from cotyledons, subculture of callus, shoot regeneration from callus, shoot-extension induction, root induction and identified the chromosome number of the plantlet. The results showed that: MS+2,4-D 2.0mg/L+KT 0.5mg/L, MS＋2,4-D 2.5mg/L＋KT 0.5mg/L, MS+2,4-D 0+KT 1.0mg/L, MS+KT 0.5 mg/L and basal MS medium. One plantlet among twenty two was determined as a tetraploidy based on the plant morphology, observation of the leaf stoma and chromosome number of the root, other two plantlets represented morphological variation.

结果表明，诱导章丘大葱子叶产生愈伤组织、愈伤组织的继代培养、愈伤组织芽分化、芽点的伸长及诱导生根的最佳培养基及激素配比分别为：MS+2，4-D 2.0mg/L+KT 0.5mg/L、MS＋2，4-D 2.5mg/L＋KT 0.5mg/L、MS+2，4-D 0+KT 1.0mg/L、MS+KT 0.5mg/L和MS基本培养基；试管苗经驯化移栽后，共有22株成活，成活率为92%，对成活的再生植株进行形态学、叶片气孔及根尖染色体鉴定表明，共有3株发生变异，其中2株为外部形态上的变异，而另一株为染色体的加倍变异。

Seeds biseriate, winged or wingless, orbicular or ovate, flattened; seed coat smooth or minutely reticulate, mucilaginous or not when wetted; cotyledons accumbent or incumbent.

种子双列，具翅的或无翅，圆形或卵形，扁平；当被弄湿时，不的种皮平滑的或微小的网状，黏的或；子叶依着的或现任。

The different explants, hypocotyl, terminal bud, cotyledonary node, seedling were studied to induce bud or callus with different concentrations of 6-BA and to establish a better system for transformation.

利用大豆不同品种的下胚轴、顶芽、子叶节、原位再生等几种外植体进行诱导植株再生的实验，并通过添加不同浓度的6-BA来观察诱导愈伤组织和出芽的情况，为下一步的转化实验建立一个良好的组培平台。
