Seed propagation of Acer negundo L. was studied in the city of Petrozavodsk (Republic of Karelia). Fruit sizes correspond to the species characteristics. The weight of monospermous mericarps is 22.1–36.2 mg. Seed germination is 11–16 %. The number of flowers, fruits and seeds per 1 total meter of last year's shoot growth was determined. The number of flowers on female trees is 274–501, on male trees – 295–540 per 1 meter. The number of fruits is 143–355, on average 274 fruits, 548 seeds per 1 meter. Seed set is 72 %. Selfseeding is limited. Acer negundo is an invasive species for many regions of Russia. In Karelia it does not manifest itself as an invasive species. The plant should not be excluded from urban greening. ...
