目的：探讨红花的种内变异及鉴别特征，为制订药、油兼用红花品种的质量评价指标，以及筛选优良栽培居群提供依据。方法：在资源调查的基础上，采集４大产地（新疆吉木萨尔、河南新乡、四川简阳和云南巍山）主要栽培居群红花的花和果实，常规制片进行显微构造观察；气相色谱法、外标曲线法测定不同栽培居群红花的脂肪酸成分和含量。结果和结论：不同栽培居群红花的果实组织构造存在差异，主要鉴别依据是外果皮石细胞胞壁增厚情况及胞腔大小。果实的油脂含量是花冠的４．０～４．５倍，花冠油脂中脂肪酸成分主要是棕榈酸（３２．７３％～３５．５３％），果实油脂中脂肪酸成分主要是亚油酸（４４．９４％～４８．６０％）。新疆吉木萨尔居群红花的油脂及其中亚油酸含量均高于其他居群
Objective: To investigate the intraspecific variation and distinguishing characteristics of safflower, and to provide basis for formulating the quality evaluation index of medicinal and oil cultivars using safflower, as well as screening excellent cultivation populations. Methods: On the basis of resource survey, the four cultivated areas (Jimulsar in Xinjiang, Xinxiang in Henan, Jianyang in Sichuan, and Lushan in Yunnan) were used to collect the flowers and fruits of the main cultivated population of safflower, and the conventional production was used to observe the microstructure; Chromatography and external standard curve method were used to determine the fatty acid composition and content of cultivars in different cultivated populations. RESULTS AND CONCLUSION: There were differences in the tissue structure of the fruit of cultivar safflower from different cultivation groups. The main identification basis was the cell wall thickening and cell size of exocarp. The oil content of the fruit is 4.0 to 4.5 times that of the corolla, and the fatty acid composition of the corolla oil is mainly palmitic acid (32.73% to 35.53%), and the fatty acid component of the fruit oil is mainly linoleic acid (44. 94% to 48.60%). The fats and oils of safflower in the population of Jimusar, Xinjiang, and their linoleic acid content in Central Asia are higher than other populations
