摘要: 用扫描电镜和光学显微镜对芒果(Mangifera indica L.)10个栽培品种的花粉形状、大小、外壁纹饰作了比较研究,结果表明:不同品种花粉粒形状、外壁纹饰等性状存在不同程度的差异,可作为区分某些品种的参考。三年芒、元江象牙、虎豹牙、红象牙、马切苏、椰香芒、大青皮、黄皮大头芒花粉外壁纹饰较为相似,可能反映出较为紧密的亲缘关系。三克里芒纹饰与以上8个品种区别较大,红光6号脊宽等性状介于二者之间。

Abstract: The Pollen grains of 10 cultivars of Mangifera indica were examined by light micro- scope (LM) and scanning electron microscope (SEM). Their shapes, sizes and exine sculptures were compared. The result showed that the pollen shapes and exine sculptures among cultivars are different in varying degrees, which can be used to differentiate various cultivars. Sannianmang, Yuanjian xiangya, Hubaoya, Hongxiangya, Maqiesu, Yexiangmang, Daqingpi and Huangpi-datoumang are similar in exine sculpture, which shows these cultivars have close rela-tionship. Sankelimang has different exine sculpture from above cativars. Huongguang No.6' sculp-ture is between Sankelimang and the above eight cultivars.
