在相同的种植和管理条件下,对普通枇杷、栎叶枇杷、大瑶山枇杷和南亚枇杷等4个种210份种质资源的8个花序性状多样性进行鉴定,旨在为进一步的分类鉴定、利用研究提供参考依据。结果表明:(1)枇杷属种质资源的花序支轴姿态、花序支轴密度、花序支轴数、花序形状、花序长度、花序宽度、花瓣颜色、花冠直径Shannon-Weaver多样性指数1.352～2.951,存在丰富的多样性。(2)不同来源地的种质资源花序性状多样性水平差异较大,多样性指数最高的为云南(2.108),其次是贵州(1.962)、四川(1.953)、福建(1.900),美国的最低(1.137)。(3)云南、贵州的枇杷种质资源花序长度、宽度显著或极显著地大于其他地区;野生资源的花序长度、花序宽度和花冠直径均极显著地大于地方品种、选育品种。
Under the same planting and management conditions, the diversity of 8 inflorescence traits in 210 germplasm resources of four species of common loquat, oak loquat, Dayaoshan loquat and South Asia loquat were identified for further classification and identification , Use of research to provide a reference. The results showed that: (1) Shannon-Weaver diversity index of flower lobe spindle, inflorescence spindle density, number of inflorescence branch, inflorescence shape, inflorescence length, inflorescence width, petal color and corolla diameter were 1.352 ~ 2.951 , There is a rich diversity. (2) The diversity of inflorescence traits in germplasm resources varies greatly from one source to another. The highest diversity index is Yunnan (2.108), followed by Guizhou (1.962), Sichuan (1.953), Fujian (1.900) and the United States (1.137). (3) The length and width of the inflorescences of loquat germplasm resources in Yunnan and Guizhou were significantly or significantly greater than those in other regions. The length of inflorescences, the width of inflorescences and the diameter of corolla were significantly higher than those of local varieties and breeding varieties.
