查询词典 lignified

方法］以生长健壮、无病虫害2年生黄花槐的半木质化枝条为材料，以清水处理为对照，研究250、500、1000 mg/L吲哚丁酸和250、500、1000 mg/L萘乙酸处理对枝条成活率、株高、平均生根数及根长的影响。

The anatomical study deepens the knowledge of G-type conducting cells: 1 It proves the theory of two depositional process for secondary wall (Bierhorst, 1960): the discontinuous cellulose layer is laid down before the continuous lignified layer; the former layer is prone to be broken down, while the latter is highly decay-resistant; 2 It suggests that the cellulose primary and secondary walls of tracheids are not perforated. Instead of longitudinal pits (Li, 1992), the lignified tracheid secondary wall of Hsüa possesses irregular simple perforations; 3 In Hsüa reflexa and Huia gracilis, the perforation casts may represent the thickness of lignified secondary wall; 4 The wall structure of G-type tracheid is diversified. At the genus level, the secondary wall structure differs in the distribution, internal shape and structure of the perforations; 5 Perforations of some G-type tracheids combine the characters of S-type tracheids in their distribution, density and diameter.

解剖学的研究加深了对G-型输水管胞的认识 1）验证了管胞次生壁分两个阶段形成的理论（Bierhorst，1960），即先后形成不连续的纤维质层和连续的木质化层，前者易被分解，后者抗侵蚀性强；2）证明管胞纤维质的初生壁和次生壁不具穿孔，Hsüa管胞的木质化次生壁具有不规则的简单穿孔，而不是纵列的纹孔（Li，1992）；3）Hsüa reflexa和Huia gracilis的穿孔铸体可代表木质化次生壁的厚度；4）G-型管胞壁层结构具多样性，植物属一级的分异主要表现在次生壁穿孔的分布、孔腔形状和结构的不同；5）某些G-型管胞的穿孔在其分布、密度和孔径方面可兼有S-型管胞的特征。

Under the scanning electron microscope , for the first time we compare and study both the coalified tracheids through chemical maceration and permineralized tracheid lumen casts. This method reveals the microstructures of wall and perforations of G-type tracheids: 1 The lignified layer of secondary wall is composed of uneven material and further divided into S〓, S〓, S〓 layers; with the smooth enclosing wall, the perforation is internally dumbbell-shaped; 2 In Huia gracilis, the enclosing wall of tracheidal perforation contracts and possesses secondary perforations. The perforation has thickened border facing the tracheid lumen.

本文首次在扫描电子显微镜下对比研究经化学浸解获得的碳质管胞和矿化的管胞腔铸体，明确揭示出了G-型管胞壁层和穿孔的显微结构：1）Hsüa reflexa次生壁木质化层的组成不均一，分为S〓、S〓和S〓层；穿孔腔为哑铃形，腔壁光滑；2）Huia gracilis的穿孔腔收缩，腔壁上发育次级穿孔，孔口具有边缘加厚。

Oreocomopsis resembles Oreocome Edgeworth, but differs in having bracts pinnate; bracteoles linear or filiform, 2–3 × umbellules; mericarp commissure narrowed; and mesocarp parenchyma not lignified.

Oreocomopsis 类似于 Oreocome Edgeworth，但是不同处为有苞片羽状（很少全缘；小苞片线形或者丝状， 2-3 倍小伞形花序；分果爿合生面缩小；以及中果皮薄壁组织而不是木质化。

The protoxylem vessels initiated lignification in the early stage of vascular bundle differentiation, whereas metaxylem vessels and fiber walls started lignification from the middle lamella and cell comers after completion of vascular bundle differentiation. The walls of most parenchyma cells lignified after the stem reached its full height, while a few parenchyma cells remained non-lignified even the culm is 7 years old.

研究结果表明：毛竹茎的原生木质部导管在维管束发育早期就已木质化；后生木质部导管和纤维细胞在维管束分化完成后，自胞间层和细胞角隅处开始木质化；基本薄壁组织细胞木质化的发生较晚，通常在茎的节间完成伸长生长后才开始，但也有少数薄壁组织细胞始终保持非木质化的薄壁状态。

Many tracheids lack protoplasm at maturity and have lignified secondary cell walls.

许多管胞的原生质体会在成熟时消失，同时细胞壁进行木质化的次生加厚。
