The peculiarities of micromorphology of 4 species and 9 breeds of actinidia leaves from the collector plantations of FSBSI ARHIBAN are visualized via scanning electronic microscopy method. The comparative analysis of micro-sculptural and quantitative morphological characteristics was performed. Species and cultivars differences of Actinidia Lindley leaves are determined. The cells of actinidia adaxial side of leaves have similar irregular polyangular, lengthened, rarely oval form. Actinidia arguta (Siebold ex Zucc.) Planch. ex Miq. and Actinidia polygama (Siebold ex Zucc.) Maxim. have flexuous, irregular polyangular, rarely oval one. Actinidia purpurea Rehd. representatives have the cells of greatly polyangular and slightly flexuous form. Actinidia kolomikta (Maxim. ex Rupr.) Maxim. cells are greatly flexuous, in the space between the ribs on the both leaf sides flat trichomes are determined which consist of 2–3 members. The perimeter and the ratio of leaves length to their width of Actinidia kolomikta leaf abaxial side is close to the adaxial side ones. To determine the perimeter of Actinidia arguta, Actinidia purpurea and Actinidia polygamа abaxial side cells is difficult due to the solid waxy layer. The minimum stomatal length is characteristic for Actinidia polygamа (9.73 μm), the maximal one is at Actinidia arguta and Actinidia purpurea (15.54 and 16.11 μm respectively). All 4 actinidia species possess short trichomes along the primary rib. For Actinidia kolomikta in comparison with the rest species more lengthened cells form of the leaf adaxial side (l/h = 1.96) is characteristic. In majority cases the substantial differences in the stomatal number between male and female forms are not found.
