摘　　要：对保存于国家果树种质福州枇杷圃备份圃的来源于云南、贵州的30份野生枇杷种质花序性状进行观察,结果表明:(1)各种质的花序长度、花序宽度、花序支轴数、花序花朵数、花冠直径的次数分布存在差异,两两间均表现为极显著正相关,变异系数22.7%～85.1%;(2)花序形状、花序支轴姿态、花序支轴紧密度和花瓣颜色等4个描述性状也表现丰富的多样性;(3)112号野生枇杷花瓣表现特异,其花瓣数平均为6.3瓣(其他种质均为5瓣)。In this paper, inflorescence traits of 30 wild loquat accessions in the national preparing nursery for loquat in Fuzhou, origined in Yunnan and Guizhou, were evaluated. The results showed： （ 1 ） The distribution of the inflorescence length, the inflorescence width, the number of inflorescence branch - axis, the number of inflorescence flowers and corolla diameter in loquat germplasm accessions were different, and the variation coefficient were 22. 7% -85.1%. It showed high significant positive correlation between every two of them. （2） There was diversity on the description characters of inflorescence in loquat germplasm, including the shape of flower cluster, attitude of secondary peduncle, density of flower cluster and color of flower axis. （ 3 ） No. 112 was a special germplasm resource with Petal number of 6. 3 on average, while the Petal number of others was 5.
