Desiccation tolerance of hypocotyl was larger than that of radicle.

下胚轴的脱水耐性大于胚根。

In the range of 20-40g/L, the growth rate of hypocotyl calli of A. crenata was positive to sucrose concentration.

在20-40 g／L范围内，朱砂根的下胚轴愈伤组织生长速率随着蔗糖浓度的升高而升高，50 g／L的蔗糖降低愈伤组织的鲜重增长率，但提高干重增长率。

During development of the seedling, the hypocotyl forms the lower portion of the stem from the radicle up to the cotyledon s

在幼苗发育期间，下胚轴从胚根到子叶的茎的下部形成。

In cotyledon, on one hand, very weak GUS staining was observed in PARF8:GUS, but very strong was found in phyA-209 PARF8:GUS. In the shoot apical meristem, hypocotyle and root tip, on the other hand, phyA-209 PARF8:GUS exhibited weaker GUS activity than PARF8:GUS. Interestedly the same expression patterns of ARF8 resulting from disruption of PhyA have been observed in dark, white-light and far-red-light conditions.

结果表明，无论在黑暗、白光和远红光条件下，PhyA突变均明显提高幼苗子叶和叶片中ARF8的表达水平，但明显降低幼苗下胚轴、茎尖和根尖中的表达水平。

Load spectrum determination of tubing inwall proves the tubing is acted by the axial alternating load in a rod pumped well, and all the fractures are located at the root of the tooth.

油管内壁载荷谱测定进一步明确了油管在工作状态下承受轴向拉-拉交变载荷，其断裂部位全部在应力集中的齿根处。

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。

A solid figure having24 equal faces, every three of which correspond to one face of an octahedron.

斜方晶有三个或三个以上类似的面，且各面均平行于一根轴的一种晶体形式

This project,"Conquest of the Northeast," makes up one important axis of Pax Sinica.

这个征服东北的计划是中国强权政治一根重要的轴。

Pekinensis . IAA at concentration of 0.4-1. 0 mg/L in solid MS medium incited many adventitious roots on hypocotyl segments. The earliest anatomic changes were observed on cut surface of hypocotyl segments under optical microscope 24 hours after IAA treatment: cytoplasmic and nuclear density became higher in a few of parenchytmatous cells adjacent to phloem in tissue of pericycle, followed by cell divisions.

在生长素诱导24h后，可借助显微切片观察到下胚轴切面附近明显的解剖学变化：首先是中柱鞘内靠近韧皮部的薄壁细胞的细胞质与细胞核变浓，染色加深，部分细胞分裂；随后是分裂的细胞团增大，逐渐形成根原基并分化出根冠。

In IR36-Shuang materials, the rate of twin seedlings with single radicle and single plumule axis was higher than that in other types.

在多胚苗材料中，单胚根单胚轴双苗所占的比例相对较大。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
