Total RNA was isolated from phloem of young shoots and retro-transcripted to cDNA by RT-PCR with specific primers, and the amplified cDNA fragments were sequenced for identification of subtypes. An effective RT-PCR technique was established for detecting citrus viroid types, and three types were recognized, i.e.

以田间柑橘枝条韧皮部为试材，提取总RNA，反转录成cDNA，再用不同类型类病毒的特异引物进行PCR扩增，鉴定出各个样品所携带的柑橘类病毒类型；通过测序分析各类型的序列，并与国内外报道的序列进行同源性分析，确定所测样品的亚型。

Branches, leaves and phloem of apple collected from an old orchard in Yanji, Xinjiang were used for total RNA isolation specific fragments of Apple fruit crinkle viroid were amplified by RT-PCR using the primers disigned according to the sequence AB104558 on GenBank. Ten sequences were obtained through recovering, cloning and sequencing, and also registered in GenBank accession No.

采集新疆焉耆地区的老果园中的苹果树枝条、叶片和韧皮部，提取总RNA，根据GenBank中的AB104558序列设计引物，利用RT-PCR技术扩增出苹果皱果类病毒（Apple fruit crinkle viroid ，AFCVd）特异条带，通过回收、克隆和测序，结果表明，获得的10条序列，已在GenBank中登录（登录号：EU031507～EU031516）。

The food-conducting tissue of vascular plants, consisting of sieve tubes, fibers, parenchyma, and sclereids.

韧皮部导管植物的食物传导组织，包括筛管、纤维、薄壁组织和硬化细胞

The results showed that the tensile strength of kenaf phloem bundle fiber had regular transverse and longitudinal distribution patterns along with the changes of plant size, plant height and phloem bundle layer.

结果表明，红麻韧皮部束纤维抗拉强度随着植株大小、植株高度及束纤维不同层次的变化在横向和纵向分布上呈现一定的变化规律，推测与红麻纤维发育期间的外界环境条件有密切关系。

Kenaf phloem bundle fiber layers were separated by five treatments, and the diameter and maximum tensile force of bundle fiber of each layer were measured.

通过5种处理方法分离红麻韧皮部束纤维层，测定各层束纤维的直径d及其所能承受的最大拉力Fmax，计算束纤维的极限抗拉强度σ。

They are common in many situations, for example as gland cells and epidermal cells, and in xylem and phloem parenchyma, where they are concerned with active loading and unloading of vessels and sieve tubes.

许多情况下都有传递细胞发挥作用，例如：腺细胞和表皮细胞，还有木质部和韧皮部的薄壁细胞，该处导管和筛管的主动装填和排空都与传递细胞有关。

Of thick bark usually located in windward habitats. The phloem color was related to the inclusion and contents of the phloem cells, especially to the tannin and resin of the phloem parenchyma and their oxidation.

但是韧皮部的颜色则与细胞内含物的多少和成分有关，尤其是韧皮薄壁细胞内的丹宁和树脂的含量以及它们在空气中的氧化作用有关。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
