到第一年年底，莖的主要結構已經被維管和軟木形成層的生長所改變。中間的髓和初生木質部一樣完整。次生木質部與初生木質部連續，延伸到維管形成層。由於射線是次生維管組織的一個特徵，次生木質部的邊界可以由射線在木質部圓筒中的起始位置來確定。在維管形成層之外是次生韌皮部，其次是原生韌皮部。在初生韌皮部可見明顯的纖維，並在初生結束後分化。韌皮部以外是皮層，由周皮層包圍。軟木形成層是莖中最後的活組織層。注意表皮脫落。三年生長：可見的明顯變化是次生木質部的生長環，韌皮部某些射線的生長在該組織中形成楔形區域。

結果 (英文) 1:

A first end of the main stem structure has been grown and vascular cambium cork changed. As complete as the middle of the pith and xylem. Xylem secondary xylem and continuously extends to the vascular cambium. Since radiation is a feature of the secondary vascular tissue, secondary xylem boundaries may be determined from the starting position of the cylinder in the xylem rays. In addition to vascular cambium is phloem, followed by primary phloem. Fibers can be seen clearly in the phloem, and primary differentiation at the end. Phloem outside skin is surrounded by a circumferential skin. Softwood forming layer is the last layer of living tissue stems. Note excoriation.
Three Growth: significant change was visible growth rings secondary xylem, phloem growth of certain rays tapered region is formed in the tissue.

結果 (英文) 2:

By the end of the first year, the main structure of the stem had been altered by the growth of the tube and the cork formation layer. The middle of the myelin is as complete as the original wood. The secondary wood part and the primary wood section are continuous, extending to the formation layer of the tube. Since rays are a feature of secondary tube tissue, the boundary of the secondary wood part can be determined by the starting position of the ray in the woodcylinder. Outside the formation layer of the vitotube is the secondary ligament skin, followed by the primary ligament skin. Visible fibers are visible in the nastonic cortex and differentiated at the end of the initial production. Outside the ligament is the cortex, surrounded by the citade. The cork formation layer is the last living tissue layer in the stem. Watch the epidermis fall off.
Three years of growth: The visible change is the growth ring of the secondary wood, and the growth of certain rays in the ligament part of the body forms a wedge-shaped region in the organization.

結果 (英文) 3:

By the end of the first year, the main structure of the stem had been changed by the growth of vascular and cork cambium. The pulp in the middle is as intact as the primary xylem. The secondary xylem is continuous with the primary xylem and extends to the vascular cambium. Because ray is a feature of secondary vascular tissue, the boundary of secondary xylem can be determined by the initial position of ray in xylem cylinder. Outside the vascular cambium is the secondary phloem, followed by the primary phloem. Obvious fibers can be seen in the primary phloem and differentiated at the end of primary. The phloem is surrounded by cortex. Cork cambium is the last living tissue layer in the stem. Pay attention to the peeling of epidermis.
Three year growth: the obvious change is the growth ring of secondary xylem, in which the growth of some rays of phloem forms a wedge-shaped area.
