This study is aimed to describe the features of seed germination of Acer saccharum Marshall in the Moscow region. The objects of the study are the fruits of three samples obtained from the arboretum Mustila (seeds were collected in the USA), Minnesota arboretum (USA) and Rochester (USA) in 2018. Morphological characteristics of fruits were described visually. To measure the fruits, a caliper was used (model “ШЦ-II-250-0.05”). Seeds were sown in pots, into a mixture of neutralized peat turf, topsoil and sand in the ratio of 3:2:1, at the depth approximately equal to the thickness of the seed. Seeds were subjected to cold stratification: the pots were kept in an unheated greenhouse for 3 winter months, with the substrate being exposed to natural temperature fluctuations, including short-term freezing. For the Mustila sample, the seeds were extracted from the mericarps. It has been shown that the smallest fruits are from the Mustila arboretum: the length and width of the nutlet are 0.787±0.025 cm and 0.565±0.018 cm respectively; the wing length and width – 1.633±0.054 cm and 0.608±0.030 cm, while they are characterized by the highest germination rate – 66.7%. Fruits from Minnesota (USA) have the largest size: the length and width of the nutlet are 1.007±0.017 cm and 0.702±0.014 cm respectively; the wing length and width – 1.968±0.042 cm and 0.791±0.021 cm; germination rate of their seeds is intermediate – 37.5%. The measurements of the fruits of the sample from Rochester exhibit intermediate values, whereas the germination rate is the lowest – 31,8%. The seed germination rate of Minnesota arboretum and Rochester samples is below that of seeds reported in the literature and is about 1/3 of the amount sown. The germination rate of Mustila sample is consistent with literature data. Nevertheless, seed reproduction of A. saccharum in the Moscow region can be considered promising.
