摘　　要：为更好地了解4个品种火龙果植物学特性及其溃疡病发生程度的差异,通过随机抽样,对4个品种火龙果植株茎、刺、叶芽等颜色、花外形特征、果实外形特征进行对比,并对溃疡病病情严重程度进行分级调查。结果表明,4个品种火龙果植物学形态特征主要差异表现:成熟枝条边缘颜色;幼刺和成熟刺的颜色;花外形、果实外形、果实表皮颜色、成熟果实纵径和溃疡病病情指数等。该研究为构建火龙果高效栽培关键技术奠定基础,从而提高当地火龙果的产量和品质,保证当地火龙果产业健康发展。To get a better understanding of the difference of botanical characteristics and the occurrence degree of canke, by random sampling, four varieties of fire dragon fruit plant stem, thorn, leaf bud and other colors, flower shape characteristics, fruit shape characteristics, and their disease of canker Yanzhongchengdu was investigated.The main differences in the morphological characteristics of the four species of fire dragon fruit were as follows: the color of the edges of mature branches, the color of young thorns and mature thorns, the shape of the flowers, the shape of the fruit, the color of the fruit’s epidermis, the longitudinal diameter of mature fruit, and various stages of canker disease. The study can lay a good foundation for the construction of high efficient culitivation techniques for the fruit of red dragon,so as to improve the yield and quality of local dragon fruit,ensure the healthy development of the local flame fruit industry.
