The Cork was consisted of five or six layer long cells. The secondary phloem occupied 46% of the diameter of root, and the parenchymas cell was abundant of the inclusions. The secondary xylem consisted of vessel, xylary radial ,and a little of xylary parenchyma cells. Some segment of hypha, swelled hypha, pelotons and conidiophore were colonied in cork and secondary phloem.

周皮由木栓层,木栓形成层和栓内层组成,其中木栓层由5~6 列长形细胞组成;维管组织中次生韧皮部所占根径的比例达46%,其薄壁细胞中内含物较丰富,次生木质部中分布有导管和木射线及少量木薄壁组织;在格木木栓层和次生韧皮部中分布有菌丝片段、膨大的菌丝和菌丝团及分生孢子。

The wood structures of Lauraceae were characterized by most diffuse porous; most pores solitary, less multiple and cluster pores; simple and scalariform perforation with few bars; most solitary pore; alternate intervessel pitting; most of rays multiseriate, less uniseriate; all of rays heterogeneous, mostly heterogeneous Ⅲ and Ⅱ type rays; most of axial parenchyma paratracheal type, less banded or marginal type; oil cell and mucilage cell in axial parenchyma cell or ray cell; mostly fiber tracheid and libriform fiber, less septate fiber.

结果表明:除檫木外,其它木材的管孔分布均为散孔材,具较高的单孔率;导管分子穿孔板兼有单穿孔和梯状穿孔2种或者仅具有单穿孔;导管间纹孔式为互列;导管-射线间纹孔式类型丰富,主要为刻痕状和大圆状。木射线有单列和多列射线2种类型,单列射线稀少、短,多列射线数量多;射线组织主要为异形Ⅲ和异形Ⅱ;轴向薄壁组织以傍管状为主,少数有带状或轮界状。油细胞和粘液细胞普遍存在于射线薄壁细胞或轴向薄壁细胞中。木纤维由韧性纤维和纤维管胞组成,部分树种具分隔纤维。

From the base to the crown in axial, the vessel-elements proportion increases in fluctuation, contrary to the ray proportion. The fiber proportions in the regions of base and crown are less than that in the trunk of tree, and fluctuate at 65% or so. The parenchym proportion increases quickly to the 1.3m height of tree, reaching the maximum at 9.52%, and then decreases quickly to the 3.3m height of tree (8.90%); afterward it leveled off and increases slightly.

组织比量轴向变异表现为随树高增加导管比量波动性递增,与木射线比量相反;纤维比量在近根区和近冠区稍小,而主干部稍大,并在65%左右波动;轴向薄壁细胞比量先随树高增加急剧增加,到1.3m树高处达最大值(9.52%)后又急剧降低至3.3m树高处的8.90%,以后基本稳定并在波动中略有增加。

The fiber length has only little influence on the basic density within the growth rings, and significant correlation at 0.01 levels was found between the basic density and the fiber length among the different rings. Only slight negative correlation was found between the basic density and the fiber width within the growth rings, but significant positive correlation at 0.01 levels was indicated between the basic density and the fiber width among the growth rings, contrary to that of fiber length. It was demonstrated that significant positive correlations at 0.01 levels between the basic density and fiber double wall thickness, fiber length to width ratio and double wall thickness to diameter ratio, significant negative correlations at 0.01 levels between the basic density and fiber diameter and diameter to width ratio, only slight negative correlation between the basic density and fiber width both in the same growth rings and among the different growth rings. No significant correlation was found between the basic density and the vessel morphological features, nor was the tissue proportion in the same growth rings. But among the different rings, it was found there was significant positive correlation at 0.01 levels between the basic density and the fiber proportion among the different rings, and significant negative correlation at 0.01 levels between the basic density and vessel-elements proportion and ray proportion, only slight negative correlation between the basic density and the parenchym proportion. Significant or no significant negative correlation was found between the basic density and the microfibril angle in the same growth rings, but significant negative correlation was found between the basic density and the microfibril angle among the different growth rings.

生长轮内纤维长度对基本密度的影响不大,而在不同生长轮间纤维长度与基本密度达极显著正相关,纤维宽度与此相反,同一生长轮内纤维宽度与基本密度极显著负相关,不同生长轮间只有微弱负相关;基本密度与纤维双壁厚、长宽比、壁腔比在生长轮内和生长轮间均呈极显著正相关,而与胞腔直径、腔径比均呈极显著负相关,仅与纤维宽度呈微弱的负相关;导管形态对基本密度的影响不显著;同一生长轮内组织比量对基本密度的影响也不显著,但不同生长轮间基本密度与纤维比量呈极显著正相关,与导管比量和木射线比量呈极显著负相关,与轴向薄壁细胞比量仅呈不显著负相关;生长轮内基本密度与微纤丝角呈显著或不显著负相关,但在生长轮间这种负相关达到极显著水平。

The callus started to produce near the surface of the wound from the remaining immature xylem cells including xylem parenchyma cells and xylem ray parenchyma cells...

愈伤组织由靠近伤口表面未成熟的本薄壁组织细胞和木射线细胞分裂产生,维管形成层在愈伤组织内层发生,且是一个渐进的过程。
