Here are the results: there are no clear difference in the length and width of leaf epidermis stomatal apparatus, stoma density and vascular bundle area in 1st internode below the ear between cold and warm type wheat. The vascular bundle area in 2nd internode below the ear of cold type wheat is obvious smaller than warm type wheat's. There are clear difference in the vascular bundle number in unit transverse area of 1st internode and 2nd internode below the ear and the rate of the total area of vascular bundle and the transverse area of wheat stem between cold and warm type wheat.

研究表明，冷、暖型小麦叶表皮气孔器的长度和宽度、气孔密度、穗下节间中维管束面积均无显著差异；冷型小麦倒二节间中维管束面积明显小于暖型小麦；冷、暖型小麦穗下节间、倒二节间单位横截面积中维管束数目、维管束总面积占茎横截面积的百分率均有显著差异。

Results The anterior bundle of ulnar collateral ligament originates from the inferior aspect of the medial epicondyle and inserts immediately adjacent to the joint surface on the ulna near the sublimis tubercle. The posterior bundle originates from the medial epicondyle slightly posterior to its most inferior portion and inserts broadly on the olecranon process. The lateral collateral ligament arises from the inferior aspect of the lateral epicondyle. Two types of conjoined lateral collateral and annular ligamentous insertions on the ulna were observed. Type Ⅰ(61.2％) was bilobate and type Ⅱ(38.8％) was a single broad conjoined type with insertion on the ulna. The anterior band of anterior bundle was more tighten than the posterior band as the elbow flexed less than 60°. When the elbow flexed over 60°, the two parts of anterior bundle were equally tightened. The posterior bundle was tightened as the elbow was flexed more than 90°. The lateral collateral ligament was tightened gradually as the elbow moved in flexion.

结果(1)尺侧副韧带前束起于肱骨内上髁的前下方，止于尺骨冠突内侧的小结节；后束起于肱骨内上髁的内下方，止于尺骨鹰嘴内侧的骨面；(2)桡侧副韧带起于肱骨外上髁的外下方，其纤维部分止于环状韧带，部分止于尺骨冠突的外下方；桡侧副韧带和桡骨环状韧带在尺骨上的止点有两种类型：Ⅰ型占61.2％，桡侧副韧带的部分纤维汇于环状韧带的尺骨止点，另一部分纤维单独止于稍远的尺骨上；Ⅱ型占38.8％，桡侧副韧带和环状韧带形成一宽的纤维止于尺骨上；(3)在肘关节屈曲60°以前，尺侧副韧带前束的外侧部紧张而内侧部较松弛，肘关节屈曲超过60°后，前束内外侧处于同程度的紧张状态；尺侧副韧带的后束在肘关节屈曲超过90°后才被拉紧；(4)桡侧副韧带在肘关节不同屈曲状态时其紧张度逐渐增加，当肘关节屈曲超过90°时，桡侧副韧带被明显拉长。

Firstly, the leaf vascular bundle turned to single vascular bundle, and becoming concrescence, the mid-part presented the pith-like parenchyma tissue, the concrescence of the different needle in one bundle formed the typical structure of the short shoot.

首先针叶中的维管束全部转变为单维管束，进而针叶基部逐渐愈合，中央部位逐渐出现类似髓部的薄壁组织，不同针叶的维管束逐渐愈合，最终形成完全具备枝条的典型结构。
