摘　　要：以宁夏枸杞(Lycium barbarum L.)宁杞1号花药培养获得的株系为研究对象,研究其叶片、花器官、果实生物学性状及果实品质,旨在获得表型良好的育种材料。结果表明,利用花药培养技术,能够创制出具有不同形态特征的种质资源,其与母株相比,叶片长度变短,部分株系叶片宽度及厚度增加,花冠直径、花柄长度减小,果实单果重、纵横径减小,种子数减少,鲜果中胡萝卜素及甜菜碱含量减少。在5份花培株系中,编号194的材料果实单果重及纵横径、糖含量均极显著高于其他材料。Taking Ningxia wolfberry(Lycium barbarum)Ningqi No.1 anther cultured strains as research objects,its leaves,flower organs,fruit biological characteristics investigation and fruit quality were studied to obtain breeding materials with good phenotype.The results show that the use of anther culture technology can create germplasm resources with different morphological characteristics.Compared with the parent plant,the leaf length becomes shorter,the leaf width and thickness of some lines increase,the diameter of the corolla and the length of the petiole decrease,the weight of the single fruit decreases,the aspect ratio decreases,and the number of seeds decreases.The content of carotene and betaine in fresh fruit reduces.Among the 5 anthropogenic lines,the fruit weight,aspect ratio,and sugar content of the material"194"were significantly higher than those of other materials.
