摘　　要：通过扫描电子显微镜对4种忍冬属植物的花粉进行观察,发现其花粉长圆球形至圆球形,金银忍冬的花粉最小,台儿曼忍冬的花粉最大。4种植物的花粉均为三环沟型,萌发沟为子午向,金花忍冬的花粉萌发沟最长,几乎到达两极。4种植物的花粉表面均具刺,有细小穿孔,台儿曼忍冬花粉表面的刺小,等大,且有规则的脊与凹坑,其他3种花粉表面的刺大小不等;忍冬的花粉表面除具细小穿孔外,还有不规则条纹。Pollens of four species in the senus Lonicera were studied by the scanning election microscope. The pollens were globular or long-globular, the smallest one was Lonicera maackii, and the largest one was L. tellmanniana,. The pollens were trizonocolpate and the colpi were meridional. The colpi of L. chrysantha were nearly to the polar. With small foreolae, the surface of pollens was echinate. The pollen of L. tellmanniana has the smallest and equational echinae, in which there have regular carinae and depression. The surface of L. japonica pollen has irregular striae.
