小黑杨是黑龙江省西部地区推广的树种之一,东北林业大学遗传育种教研室于1974年用小黑杨花药培养,成功的诱导出不同类型的花粉植株,大致分绿皮型和粗皮型。本文对这两种类型的叶子进行了解剖观察并与其小黑杨、小叶杨及黑杨进行比较。两种类型的花粉植株叶厚大于小黑杨并与黑杨相似。从叶表皮看花粉株表皮细胞外壁的角质层 Populus simonii is one of the tree species popularized in the western region of Heilongjiang Province. The Department of Genetics and Breeding, Northeast Forestry University, was cultivated with the anthers of Populus nigra in 1974, successfully inducing different types of pollen plants, roughly divided into green-type and coarse-type. In this paper, anatomical observation of these two types of leaves was carried out and compared with that of Populus simonii, Populus simonii and Populus nigra. Both types of pollen plant leaf thicker than the black poplar and black poplar similar. The stratum corneum of outer wall of pollen plant epidermal cells from leaf epidermis
