目的：研究不同栽培居群红花各器官的组织构造和化学成分含量，为不同栽培居群红花的鉴别及资源的扩大利用提供依据。方法：在对４个栽培居群红花进行引种栽培的基础上，常规石蜡切片进行不同器官组织构造观察，ＵＶ，ＨＰＬＣ法测定不同器官的化学成分含量。结果：描述了红花各器官的组织特征。同一栽培居群红花不同器官间及不同栽培居群红花相同器官间化学成分含量均存在差异（Ｐ＜０．０１），黄色素含量花冠高于根、茎、叶器官（Ｐ＜０．０１），居群间巍山居群＞简阳居群＞新乡居群＞吉木萨尔居群（Ｐ＜０．０１）；腺苷含量叶片高于根、茎、花器官（Ｐ＜０．０１），居群间吉木萨尔居群＞简阳居群＞新乡居群＞巍山居群（Ｐ＜０．０１）。结论：４个栽培居群红花组织构造及化学成分含量均存在差异。花冠是黄色素积累的主要器官，巍山居群含量最高；叶片是腺苷积累的主要器官，高出花冠５．５～１２．７倍，吉木萨尔居群含量最高，应重视红花叶片资源的利用。
OBJECTIVE: To study the structure and chemical composition of various organs of safflower in different cultivation populations, and to provide basis for the identification of different cultivated populations of safflower and the use of resources. METHODS: Based on the introduction and cultivation of four cultivated populations of safflower, regular paraffin sections were used to observe the structure of different organs. UV and HPLC were used to determine the chemical composition of different organs. Results: The characteristics of the organs of safflower were described. The contents of chemical components in different organs of safflower and different cultivated populations in the same cultivated population were different (P<0.01). The content of yellow pigment in corolla was higher than that in root, stem and leaf organs (P<0. 01), between populations Laoshan population> Jianyang population> Xinxiang population> Jimsar population (P<0.01); adenosine content leaves higher than roots, stems, floral organs (P<0.01) , Population between Jimusal population> Jianyang population> Xinxiang population> Lushan population (P<0.01). Conclusion: The structure and chemical composition of safflower in four cultivated populations are different. Corolla is the main organ for accumulation of yellow pigment. The content of Laoshan population is the highest. Leaf is the main organ for accumulation of adenosine, which is 5.5 to 12.7 times higher than the corolla. The content of Jimusar population is the highest. The safflower leaf resources should be valued. Use.
