Coconut wood (Cocos nucifera L.), an economically significant tropical tree, exhibits variations in fiber morphology and chemical composition that directly influence its processing performance and comprehensive utilization potential. This study systematically investigated the spatial variability of fiber morphological indices (length, width, cell wall thickness, lumen diameter, aspect ratio, and cell wall-lumen ratio) and chemical components (holocellulose, cellulose, and lignin) across different trunk heights (bottom, middle, top) and radial positions (outer, middle, inner) in 40-year-old coconut trees from Hainan. The analyses were conducted using wood microscopy, image analysis software, and chemical assays. Fiber length (696.84–969.94 μm), cell wall thickness (9.78–18.36 μm), and cell wall-lumen ratio (1.13–5.82) decreased significantly from the bottom to the top, while lumen diameter (3.60–10.15 μm) increased. Fiber width (17.41–20.76 μm) and aspect ratio (40.39–48.79) showed minor variations but exhibited an overall downward trend with increasing height. Fiber length, cell wall thickness, and cell wall-lumen ratio decreased from the outer to inner regions, whereas lumen diameter increased. Chemical analysis indicated decreasing trends for holocellulose (59.14%–70.32%) and cellulose (41.03%–44.85%) content along both vertical and radial gradients, while lignin (21.40%–23.60%) initially decreased and then increased vertically, with higher inner-region content. The study identified superior fiber morphology (longer fibers, thicker cell walls, smaller lumen diameters) and higher holocellulose and cellulose content in the bottom and outer regions. Compared to bamboo, coconut fibers are thicker, with thicker cell walls and smaller lumens but lower aspect ratio, making them particularly suitable for medium-to-short fiber pulping processes. This research elucidates the spatial variation mechanisms of coconut wood fiber morphology and chemical composition, could providing a theoretical foundation for optimizing pulping, fiberboard manufacturing, and bioenergy applications, Such insights can enhance resource utilization efficiency and support sustainable development in tropical timber industries.

椰子木(Cocos nucifera L.)作为热带地区重要的经济树种,其纤维形态和化学成分直接影响其加工性能和综合利用潜力。本研究以海南儋州树龄40 a高种椰子木为对象,采用光学显微观察、图像测量及化学成分测定方法,系统研究不同树干高度(底部、中部、上部)和径向部位(外部、中部、内部)纤维的形态指标(长度、宽度、壁厚、腔径、长宽比及壁腔比)和主要化学成分(综纤维素、纤维素、酸不溶木素)的空间变异特征。结果表明:高度方向上,纤维长度(696.84~969.94 μm)、壁厚(9.78~18.36 μm)和壁腔比(1.13~5.82)从底部至上部呈显著递减,腔径(3.60~10.15 μm)则呈递增;纤维宽度(17.41~20.76 μm)和长宽比(40.39~48.79)变化较小,但整体随高度的增加呈下降趋势。径向方向上,纤维宽度、壁厚及壁腔比由外部向内递减,而纤维长度、长宽比和腔径则呈递增。化学成分分析结果显示,综纤维素(59.14%~70.32%)与纤维素含量(41.03%~44.85%)随高度和径向增加而下降;酸不溶木素含量(21.40%~23.60%)则在高度上呈先降后升,在径向上呈递增。总体来看,椰子木底部和外部区域纤维表现为长纤维、厚壁、小腔径,对应较高的综纤维素和纤维素含量,更有利于制浆利用。与竹材相比,椰子木纤维具有粗而短、高壁厚、高壁腔比和低长宽比的形态特性,表明其适用于中短纤维制浆。本研究揭示椰子木纤维形态与化学成分的空间分布规律,为其在制浆造纸、纤维板及生物能源利用方面提供理论依据,对提升椰子木资源利用率和促进热带木材产业可持续发展具有重要意义。

椰子木(Cocos nucifera L.)作为热带地区重要的经济树种,其纤维形态和化学成分直接影响其加工性能和综合利用潜力。本研究以海南儋州树龄40 a高种椰子木为对象,采用光学显微观察、图像测量及化学成分测定方法,系统研究不同树干高度(底部、中部、上部)和径向部位(外部、中部、内部)纤维的形态指标(长度、宽度、壁厚、腔径、长宽比及壁腔比)和主要化学成分(综纤维素、纤维素、酸不溶木素)的空间变异特征。结果表明:高度方向上,纤维长度(696.84~969.94 μm)、壁厚(9.78~18.36 μm)和壁腔比(1.13~5.82)从底部至上部呈显著递减,腔径(3.60~10.15 μm)则呈递增;纤维宽度(17.41~20.76 μm)和长宽比(40.39~48.79)变化较小,但整体随高度的增加呈下降趋势。径向方向上,纤维宽度、壁厚及壁腔比由外部向内递减,而纤维长度、长宽比和腔径则呈递增。化学成分分析结果显示,综纤维素(59.14%~70.32%)与纤维素含量(41.03%~44.85%)随高度和径向增加而下降;酸不溶木素含量(21.40%~23.60%)则在高度上呈先降后升,在径向上呈递增。总体来看,椰子木底部和外部区域纤维表现为长纤维、厚壁、小腔径,对应较高的综纤维素和纤维素含量,更有利于制浆利用。与竹材相比,椰子木纤维具有粗而短、高壁厚、高壁腔比和低长宽比的形态特性,表明其适用于中短纤维制浆。本研究揭示椰子木纤维形态与化学成分的空间分布规律,为其在制浆造纸、纤维板及生物能源利用方面提供理论依据,对提升椰子木资源利用率和促进热带木材产业可持续发展具有重要意义。

Coconut wood (Cocos nucifera L.), an economically significant tropical tree, exhibits variations in fiber morphology and chemical composition that directly influence its processing performance and comprehensive utilization potential. This study systematically investigated the spatial variability of fiber morphological indices (length, width, cell wall thickness, lumen diameter, aspect ratio, and cell wall-lumen ratio) and chemical components (holocellulose, cellulose, and lignin) across different trunk heights (bottom, middle, top) and radial positions (outer, middle, inner) in 40-year-old coconut trees from Hainan. The analyses were conducted using wood microscopy, image analysis software, and chemical assays. Fiber length (696.84–969.94 μm), cell wall thickness (9.78–18.36 μm), and cell wall-lumen ratio (1.13–5.82) decreased significantly from the bottom to the top, while lumen diameter (3.60–10.15 μm) increased. Fiber width (17.41–20.76 μm) and aspect ratio (40.39–48.79) showed minor variations but exhibited an overall downward trend with increasing height. Fiber length, cell wall thickness, and cell wall-lumen ratio decreased from the outer to inner regions, whereas lumen diameter increased. Chemical analysis indicated decreasing trends for holocellulose (59.14%–70.32%) and cellulose (41.03%–44.85%) content along both vertical and radial gradients, while lignin (21.40%–23.60%) initially decreased and then increased vertically, with higher inner-region content. The study identified superior fiber morphology (longer fibers, thicker cell walls, smaller lumen diameters) and higher holocellulose and cellulose content in the bottom and outer regions. Compared to bamboo, coconut fibers are thicker, with thicker cell walls and smaller lumens but lower aspect ratio, making them particularly suitable for medium-to-short fiber pulping processes. This research elucidates the spatial variation mechanisms of coconut wood fiber morphology and chemical composition, could providing a theoretical foundation for optimizing pulping, fiberboard manufacturing, and bioenergy applications, Such insights can enhance resource utilization efficiency and support sustainable development in tropical timber industries.

椰子(Cocos nucifera L.)作为热带地区重要的经济作物,既是海南的省树,也是支撑区域经济的重要产业。近年来,海南省椰子种植面积持续扩大,从2018年的3.44万hm2增至2022年的3.91万hm2,占全国总种植面积的90%以上[1-4]。然而,每年因种植更新产生的大量椰子木更新材中,因缺乏有效利用途径,多数被就地填埋或焚烧,既造成木材资源的严重浪费,更引发环境污染风险。因此,开发椰子木的综合加工利用技术,不仅有助于缓解我国木材供需矛盾,也对提升椰子产业附加值和实现社会、经济、生态效益的协调发展具有重要意义。
在木材应用领域,椰子木因独特纹理及良好的力学性能,已在家具、地板、桁架、横梁等承重结构,以及正交胶合木和吸音材料等产品中得到应用[5-8]。然而,椰子木内部维管束分布不均、材性变异显著,导致制材加工难度高、锯材性能稳定性不足,从而限制了其高效利用[9]。要提升其资源化利用水平,亟需从纤维形态和化学成分层面揭示结构特征与利用潜力之间的关系。
目前,国内外学者针对棕榈科植物维管束开展了较多研究,如有关油棕木纤维形态、分布规律及化学成分等方面已有报道[10-13],但针对椰子木纤维形态与化学成分,尤其是不同部位变异性的系统性研究尚少。作为同属棕榈科的典型植物,椰子木材性变异是否与其纤维形态相关,纤维在高度方向(底部、中部、上部)及径向部位(内部、中部、外部)的分布是否存在规律性,以及其纤维特性与其他材料的差异,均需深入探究。
植物的纤维形态与化学成分是决定木材制浆造纸、人造板生产等纤维化利用的重要因素。随着造纸业的发展,木质纤维需求的增加对拓宽椰子木的利用具有潜在的价值。椰子木维管束主要由厚壁纤维细胞组成,其纤维长度、宽度及长宽比等形态特征及化学成分中综纤维素、木质素含量的变异规律,直接影响纤维的力学性能、化学可及性及加工适用性[6]。目前,椰子木在制浆造纸和人造板工业中的应用潜力尚未被充分挖掘,关键原因在于缺乏对其纤维基础特性及化学成分的系统性研究。
基于此,本研究以中国海南儋州地区高种椰子木为研究对象,系统分析纤维形态(长度、宽度、壁厚等)与化学成分(综纤维素、纤维素和酸不溶木素)在树干高度和径向部位的变异规律特征。旨在揭示椰子木纤维特性与化学成分的空间变异规律,探明纤维形态与化学成分对纤维化加工性能的影响,为椰子木在制浆造纸、人造板及其他生物质利用领域的高效开发提供理论依据。
试验材料椰子木3株,品种均为海南高种,树高分别为10、11、13 m,树龄为40 a,采自海南儋州市沙河水库两院试验场,地理坐标19°49ʹN,109°51ʹE,海拔126 m。
将砍伐的椰子木沿树干高度1.0、5.0、9.0 m处截取厚3 cm的圆盘各1个,分别标记为底部、中部、上部;将圆盘沿横断面径向方向由外至内均匀截取规格为20 mm×20 mm×30 mm(径向×弦向×纵向)的三部分试材,分别对应标记为外部、中部、内部(图1),试样共计9组(底外、底中、底内、中外、中中、中内、上外、上中、上内)。所有试材置于恒温电热鼓风干燥箱内,65 ℃条件下干燥至含水率约12%以备用。
将试样劈成小细条,混匀,随机取若干条试样放入试管中,倒入30%过氧化氢和99.5%冰醋酸(体积比为1∶1)的混合液,放入70~80 ℃水浴锅中加热离析,直至试样淡白或边缘开始离析为止,倒出混合液,用蒸馏水冲洗数次至干净。最后加入少量蒸馏水至试管,用拇指按住试管口轻轻震荡使纤维充分离析分散。用镊子夹取少量纤维转移至载玻片上,滴入番红染色,盖上盖玻片,用吸水纸吸去多余的水分。使用Leica显微镜成像系统获取图像,选用10倍物镜测量纤维长度,40倍物镜测量纤维宽度、壁厚和腔径,每组样品随机150根纤维以上。使用Digimizer图像测量分析软件测量纤维长度和宽度等形态指标。
将样品劈开成火柴大小的小木条,在温度为65 ℃的恒温干燥箱内干燥至质量恒定,然后用微型木材粉碎机粉碎木条,最后粉末过40目分样筛以备用。按照国家标准GB/T 2677.8—1994《造纸原料酸不溶木素含量的测定》、GB/T 2677.10—1994《造纸原料综纤维素含量的测定》,分别测定酸不溶木素、综纤维素。纤维素的测定采用硝酸-乙醇法[14]
采用双因素方差分析(Two-way ANOVA)探究高度和径向部位对各指标的影响,通过Duncan检验法进行组间差异比较(P<0.05),使用R软件(Version 4.5.0)完成统计分析。
在高度方向,椰子木纤维长度从底部至上部显著递减。底部、中部、上部纤维长度均值分别为969.94、834.43、696.84 μm(表1)。底部、中部、上部纤维长度主要分布在600~1400、400~1200、400~1000 μm区间,占比频率分别为83.33%、87.99%、82.89%(图2),此变化可能与维管束内纤维细胞发育成熟度有关,底部纤维细胞发育时间更长,纤维细胞延伸更充分。
在径向方向,纤维长度从外部到内部呈先增大再减小的变化规律,差异显著。外部、中部、内部的均值分别为814.98、877.65、808.58 μm(表1)。分布频率(图2)表明,外部、中部、内部的纤维长度主要分布在400~1400 μm区间,整体上中部位置的纤维长度更长些,分布峰值相对于外部和内部更大一些。根据国际木材解剖协会关于木材纤维长度分级标准,长度为<900 μm属于短纤维,900~1600 μm属于中等纤维,>1600 μm属于长纤维。基于此分类,椰子木底部的纤维属于中等纤维,中部和上部属于短纤维[15],显示椰子木整体更适用于中短纤维制造。
在高度方向,椰子木纤维宽度从底部到上部逐渐减小,且差异显著。底部、中部、上部的平均值分别为20.76、17.56、17.61 μm(表1)。随高度升高,纤维宽度略有下降趋势,表明上部细胞相对较为纤细,可能受限于纤维细胞横向拓展空间。底部、中部、上部的纤维宽度主要分布在15~27、12~24、12~21 μm区间,频率占比分别为88.66%、90.00%、90.88%(图3)。
在径向方向,椰子木纤维宽度从外部到内部逐渐减小,外部、中部、内部纤维宽度平均值分别为19.54、18.98、17.41 μm。不同高度上的径向方向,外部、中部、内部的分布频率与该高度的分布一致,总体分布在12~24 μm之间(图3)。
在高度方向,纤维长宽比从底部向上总体呈现减小趋势,底部、中部、上部纤维长宽比平均值分别为47.51、48.79、40.39(表1)。纤维长宽比的分布范围有一定的差异性,底部、中部和上部的长宽比主要分布在30~60、30~70、20~60区间,分布频率分别为73.77%、77.90%、90.88%(图4)。根据纤维制浆性能的评价标准,优质纸浆原料的长宽比应在80以上[16],椰子木纤维普遍偏低,说明其更适用于中短纤维纸浆制品。在径向方向,纤维长宽比从外到内呈现递增规律,外部、中部、内部纤维长宽比平均值分别为42.31、46.86、47.53(表1)。纤维长宽比在外部、中部和内部主要分布在20~70区间(图4)。
木纤维的壁厚不仅影响纤维品质,还直接影响纸张的品质。壁薄、壁腔比小的纤维原料,可压扁性好,能赋予纸张较好的纤维结合强度,成纸质地紧密[17]。在高度方向,椰子木纤维壁厚从底部到上部递减,且差异显著。底部、中部、上部纤维壁厚平均值分别为18.36、11.96、9.78 μm(表1)。底部、中部和上部,纤维壁厚主要分布在10~24、8~16、6~14 μm区间,分布频率分别为83.78%、75.55%和83.76%(图5)。底部纤维壁厚超过18 μm,说明该区域具有良好的机械支撑能力。在径向方向,纤维壁厚从外部到内部显著递减,外部、中部、内部纤维壁厚平均值为15.12、13.22、11.75 μm(表1)。外部、中部和内部纤维壁厚主要分布在6~24 μm区间(图5)。
在高度方向,纤维腔径从底部到上部递增,与纤维的壁厚变化正好相反,不同高度的纤维腔径差异显著。底部、中部、上部纤维腔径平均值分别为3.60、7.28、10.15 μm(表1),这表明随着椰子木高度的增加,纤维壁厚变小,腔径变大。底部、中部和上部纤维腔径主要分布在2~6、2~10、4~14 μm区间,分布频率分别为86.70%、82.00%和81.11%。在径向方向,纤维腔径从外部到内部递增,外部、中部、内部纤维腔径平均值分别为6.15、7.16、7.71 μm(表1)。外部、中部和内部纤维腔径主要分布在2~14 μm区间(图6)。
壁腔比小的纤维原料,可压扁性好,在纤维之间容易形成较大的接触面,可赋予纸张较好的纤维结合强度,成纸质地紧密[17]。在高度方向,椰子木纤维壁腔比从底部到上部递减,不同高度的纤维壁腔比差异显著。底部、中部、上部纤维壁腔比平均值分别为5.82、1.94、1.13(表1)。底部、中部和上部纤维壁腔比主要分布在2~10、0~3和0~2区间,分布频率分别为92.21%、87.78%和92.66%(图7)。在径向方向,椰子木壁腔比从外部到内部递减,不同径向部位的壁腔比差异显著。外部、中部、内部纤维壁腔比平均值分别为3.78、2.93、2.18(表1)。底部高度位置的外部、中部和内部纤维壁腔比主要分布分别在4~11、3~10和2~6区间,而中部和上部高度位置的外部、中部和内部纤维壁腔比均主要分布在0~3区间(图7)。
通过对椰子木主要化学成分(综纤维素、纤维素、酸不溶木素)的测定发现,其含量在树干高度和径向部位上存在显著空间变异。不同高度(底部、中部、上部)及径向部位(外部、中部、内部)的化学成分含量差异明显,具体测定结果见表2
综纤维素是指木材中除去木质素以外的全部碳水化合物组分的总和,主要包括纤维素和半纤维素。在造纸过程中,植物的综纤维素含量越高,其纸浆率越高[18]。椰子木综纤维素总体含量为59.14~70.32%,平均值为64.51%(表2),在高度方向,综纤维素含量随着高度增加而递减,底部、中部和上部的综纤维素含量分别为67.80%、63.46%和62.28%(表2)。径向方向,综纤维素含量从外部到内部逐渐减小,外部、中部和内部的综纤维素含量分别为70.32%、64.07%和59.14%(表2)。底部和外部区域综纤维素含量最高,反映出其细胞成熟度高、维管束密度高、次生壁发达的结构特征,这些区域也是制浆造纸中最具利用潜力的部分。
木材纤维素是构成木材细胞壁的主要结构性多糖,是纸张纤维的主要成分,其长度、聚合度和结晶度直接影响纸张的强度[16]。椰子木纤维素总体含量为41.03~44.85%,平均值为43.05%(表2)。在高度方向,纤维素含量随着高度增加而递减,底部、中部和上部的纤维素的含量分别为43.84%、43.31%和41.99%;在径向方向上,纤维素含量从外部到内部逐渐减小,外部、中部和内部的纤维素含量分别为44.85%、43.26%和41.03%(表2)。
酸不溶木素是木质素的一种分类形式,是指在特定酸性条件下不溶于酸溶液的木质素组分,是植物细胞壁的重要化学成分[19]。椰子木的酸不溶木素总体含量为21.40~23.60%,平均值为22.40%(表2)。在高度方向,酸不溶木素随着高度的增加先减小后增加,底部、中部和上部酸不溶木素的含量分别为23.47%、21.40%和22.33%;在径向方向,酸不溶木素含量从外部到内部递增,外部、中部和内部的酸不溶木素含量分别为21.71%、21.89%和23.60%(表2)。
椰子木纤维形态特征与维管束发育密切相关。本研究显示,椰子木纤维平均长度为833.74 μm,宽度为18.64 μm,壁厚为13.37 μm,长宽比为45.57,呈现出纤维长度中等、直径较粗、壁厚腔小的形态特征。在高度方向,纤维长度与壁厚自底部向上部呈现显著递减趋势,纤维长度变化范围为696.84~969.94 μm,壁厚变化范围为9.78~18.36 μm,而纤维宽度变化不明显。这种高度分布与纤维细胞的发育阶段及木质化程度密切相关:底部纤维细胞因形成时间早,次生壁物质持续积累,木质化程度较高,因此具有较大的纤维长度与壁厚,能够为树体提供较强的力学支撑;而上部纤维细胞处于发育早期阶段,细胞壁较薄且纤维较短。在径向分布,纤维长度、宽度和壁厚由外部向内部逐渐减小。
与竹纤维相比,椰子木纤维在形态上变化明显。竹纤维(如毛竹、慈竹)平均长度更长(1.83~2.00 mm),但其宽度(15.0~16.2 μm)和壁厚(6.45~6.68 μm)均低于椰子木[20-21]。此外,椰子木纤维长宽比(45.57)显著低于竹纤维(74.38~170.70),表明其形态更为粗短[22]。这种差异源于生长模式的根本不同:竹材通过快速高生长形成轴向力学优化结构,纤维长度在中部达到峰值以平衡支撑效率;而椰子木生长缓慢,底部纤维因纤维细胞次生壁长期沉积形成厚壁结构,形成“底部强、顶部弱”的高度梯度,以适应树冠重量支撑及抗风摆动生理需求。值得注意的是,竹材纤维壁厚随竹龄增加而增厚[17,23],而椰子木底部纤维的高壁厚(平均13.37 μm)则是长期木质化积累的结果,这与木材的成熟机制相似,但椰子木的缓慢生长使其底部纤维具备更稳定的力学结构。
从制浆性能角度看,竹纤维的高长宽比(如毛竹约123.5)使其更适于生产高强度纸张[24-25],而椰子木纤维的粗短形态(长宽比45.57)可能降低成纸的耐折度与撕裂强度。然而,椰子木纤维的高壁厚与壁腔比(平均2.97)使其刚性更强,可能更适用于高密度纸板或纤维复合材料。研究还发现,油棕木纤维虽与椰子木类似,呈现壁厚随高度递减的趋势,但其纤维长度变化不显著[26],进一步证实了木本单子叶植物底部纤维强化机制的普遍性。
综上,椰子木纤维形态的分布规律是其生长适应性应对调控的结果。这一结果为椰子木纤维的定向利用提供理论依据,例如优先选用底部及外部区域的高性能纤维用于高强度材料,同时通过工艺调控优化纤维分离与改性工艺。针对上部及内部区域纤维壁薄、腔径大、木质素含量较高的特点,可通过预处理改善其化学可及性。在制浆造纸中,结合底部纤维高壁腔比的刚性优势,可设计差异化蒸煮工艺以提升纸浆质量。针对纤维长宽比偏低的共性特征,可通过纤维复合技术弥补成纸性能短板,从而实现全树范围内不同部位纤维资源的高效分级利用。
椰子木的综纤维素、纤维素及酸不溶木素含量在树干高度与径向部位呈现显著空间梯度分布,其变异规律与维管束密度、纤维细胞发育进程密切相关。高度方向,综纤维素与纤维素含量自底部至上部递减,酸不溶木素含量呈先降后升分布,其中底部综纤维素(67.80%)和纤维素(43.84%)含量分别比上部高8.9%和4.4%,显示出基部组织的资源优势;径向方向,综纤维素(59.14%~70.32%)与纤维素(41.03%~44.85%)含量由外向内递减,酸不溶木素(21.71%~23.60%)则表现为内部显著高于外部;FATHI等[26]研究的椰子木综纤维素(66.7%)、纤维素(42%)和木质素(25.1%)含量与KOLYA等[27]研究的椰子木纤维素(27.0%)、半纤维素(34.9%)和木质素(29.3%)的含量具有差异性,纤维素和木质素差异都较大。本研究的结果与FATHI的结果类似,这一差异可能来自不同部位、树龄和品种的差异。研究表明海南高种椰子木纤维的纤维素和木质素含量高于矮种椰子,这与相关合成基因的拷贝数扩张、高表达水平、以及关键结构变异相关[28]
该分布特征与维管束组织分布的空间变异直接相关:外部及底部区域因维管束密度高,纤维细胞占比大,次生壁中纤维素与半纤维素积累充分,而内部区域随薄壁细胞比例增加,木质素相对含量上升。这与RAMLE等[10]在油棕木纤维中的研究结论一致,进一步证实维管束组织中纤维细胞对综纤维素和纤维素的主导积累作用。与毛竹相比,椰子木综纤维素和纤维素含量略低,但显著高于油棕[26-27],木质素含量与二者相当[16,29],体现了维管植物化学成分的共性特征。
化学成分的空间变异对制浆造纸及纤维复合材料加工利用具有关键指导意义:底部与外部区域因高综纤维素(>67%)、低酸不溶木素(<22%)的优势,纤维结合力强且纸浆得率高,是优质纸浆原料的理想取材部位;内部区域因酸不溶木素含量较高(>23%),需通过强化脱木素工艺降低加工难度。工业生产中优先取材于树干基部及外围区域进行加工利用。
本研究系统揭示海南树龄40 a的高种椰子木纤维形态及化学成分在树干高度和径向部位的空间变异规律,为定向开发制浆造纸、纤维板材及复合材料等高性能产品提供科学依据。
椰子木纤维形态在高度和径向方向呈现显著梯度变化。在高度方向,纤维长度、壁厚及壁腔比自底部至上部递减,腔径递增;纤维宽度与长宽比整体呈下降趋势。在径向方向,纤维宽度、壁厚及壁腔比由外部向内部递减,纤维长度、长宽比及腔径递增。底部和外部区域纤维形态最优,表现为长纤维、厚壁、低腔径,是纤维加工的优质取材部位。
化学成分在高度和径向方向亦存在显著差异。综纤维素与纤维素含量在高度和径向方向均呈递减趋势,酸不溶木素含量在高度方向先降后升,径向方向内部高于外部。底部和外部区域因维管束密度高,综纤维素和纤维素含量更高,制浆潜力更大。
