The correlation analysis indicated that the apple fruitlet weight was significantly positively correlated with the total Ca, Mg, K content of single fruitlet, and also with the diameter, number of vascular bundles, xylem thickness and phloem vascular bundles area of pedicel.

相关分析表明，苹果幼果的单果重和Ca、Mg、K含量与果柄的直径、维管束数目、木质部厚度、韧皮部维管束面积呈显著正相关，说明幼果发育与Ca、Mg、K吸收和果柄结构密切相关，Ca、Mg、K吸收率低和果柄发育不良可能是导致落果的重要原因。

Biochemical analysis and histochemical localization techniques were used to assess changes and distribution of peroxidases in the recovering bark after girdling in Eucommia ulmoides Oliv..

ABP1的表达大致上与生长素的分布一致，在组织水平上，ABP1主要位于形成层和正在径向扩大中的次生木质部细胞中。

Scalariform thickening A type of secondary wall formation consisting of interlaced helical bands of thickening giving a ladderlike formation. It allows for very little further extension, and is found in tissues such as metaxylem tracheids and vessels, which do not elongate after maturation.

梯纹加厚：是植物细胞次生壁的一种形态结构，壁由加厚过程中相互交错成梯状形态的螺旋带形成，其可延伸性很小，多存在于后生木质部管胞和导管等一些成熟后便不再延伸的管状分子中。

The secondary xylem of woody plants is a product of the vascular cambium,its formation is a complicated type of plant cell differentiation, including cambium initiation, cambial cell division, cell expansion, secondary wall deposition and programmed cell death.

木本植物的次生木质部是维管形成层的活动产物，其形成过程是植物细胞分化的一种复杂类型，包括维管形成层发生、形成层细胞分裂、分化、细胞扩展、次生壁形成和细胞程序化死亡等阶段。

Using electronic microscopy and cytochemical methods, we studied the distribution changes of the cell ergastic substance and development of secondary vascular tissues. Development of secondary vascular tissue took on an inherent rhythm, showing alternation of dormant and differentiated stages in periodicity of one year, and the formation of secondary phloem and xylem was alternate.

利用电镜技术及细胞化学方法，研究了美洲黑杨次生维管组织的发育以及细胞内含物分布的变化，发现次生维管组织的发育具有内在节律性，在年周期中表现为分化期和休眠期交替出现；次生韧皮部与次生木质部交替分化形成。

Emblica have many different forms and most of them have tails and their perforation plates divide into two types:(1)there is one simple perforation plate at each end of the vessel elements and (2) there is one simple perforation plate at one end of the vessel elements and two simple perforation plate at the other end;(3)a few vessel elements have special inclusions;(4)the intervascular pits are alternate pits;(5)the pits between the vessels and rays are mixed pits ,pits with transverse gashes and scalariform pits.

结果发现，余甘子次生木质部导管分子中存在着许多不同的样式，导管分子大多数具尾；其穿孔板存在着两种类型：(1)两端均为1个单穿孔板；(2)一端为1个单穿孔板；另一端为2个单穿孔板；(3)极少数的导管分子具有特殊的内含物；(4)管间纹孔式为互列纹孔式；(5)导管射线间纹孔式为混合型纹孔与横列刻痕状纹孔以及梯状穿孔。

Vascular cambium The ring of CAMBIUM formed by the activity of the interfascicular cambium and the intrafascicular cambium that gives rise to secondary xylem and secondary phloem.

维管形成层：由于维管束内形成层和束间形成层的活动产生的环状形成层结构，它的分裂活动可以形成次生木质部和次生韧皮部。

Intrafascicular CAMBIUM between xylem and phloem. Apical initials are rarely single cells except in certain lower plants, and initiate more than one structure, e.g.

这种细胞存在于根和芽的顶端分生组织以及在原来分裂组织基础上形成的侧生分生组织，如位于木质部和韧皮部之间的束中形成层。

Acetone-water at 60℃water bath for 60min and solid to liquid ratio 1:50 for twice. 2.Through the optimal method analysis phenol content in leave,phloem and xylem from the different breeds of Pistacia vera L.

应用阿月浑子总酚最佳的提取工艺条件对不同生长时期阿月浑子和黄连木不同品种的叶片、韧皮部、木质部中的总酚含量动态变化进行分析。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
