Uskokrila ili kineska pterokarija, je listopadna brzorastuća drvenasta vrsta do 20 m visine, sa granama koje horizontalno rastu stvarajući krošnju čija širina je približna visini. Plodovi su viseće skupine krilatih orašica, dužine 15-30 cm koje tokom sazrevanja u jesen poprimaju braon boju. Vrsta nije opisana od strane domaćih autora. Seme uskokrilate pterokarije je sakupljeno sa matičnog stabla koje se nalazi u Arboretumu Šumarskog univerziteta u Sofiji (Lesotehničeski universitet, Sofija). Seme je stratifikovano u perlitu i bez supstrata, tzv. gola stratifikacija tokom perioda od jednog i dva meseca. Vrednosti tehničke klijavosti ukazuju na razlike između tretmana. Najveći procenat klijavosti dali su kraći tretmani, jednomesečne stratifikacije u perlitu (56.5%) i gole jednomesečne stratifikacije (51%), bez međusobno statistički značajne razlike. Apsolutna klijavost svih tretmana se kreće od 69.8% do 88%. Ovako visoke vrednosti apsolutne klijavosti u poređenju sa tehničkom klijavošću ...ukazuju da je preko 40% semena u uzorku šturo. Rezultati kontrolnih tretmana ostalih parametara klijanja ukazuju da kod vrste nije prisutan dubok oblik embrionalne dormantnosti, ali da je seme rekalcitrantno i mikrobiotsko. Rezultati ukazuju na neinvazivan karakter ove vrste.
The Small-winged wingnut is a 12 to 20 metres tall, deciduous and fast growing tree with large substantial branches that spread as wide as the tree is tall. The 15 to 30 cm long winged fruit catkins, which turn brown in the autumn, are suspended below the branches. The species is not described by domestic authors in Serbia. The seed was introduced from Sofia (from the Arboretum of the Forestry University of Sofia, Bulgaria - Lesotehničeski universitet, Sofija), and subjected to classical stratification and naked stratification during the period of 1 and 2 months. Germination capacity varied among the treatments. The largest number of germinated seeds was observed in the shorter stratifications, (1 month) the classical (56.5%) and the naked (51.0%) with no significant difference. The values of real germination of all treatments were between 69-88%. High value of RG, compared to GC, indicated that more than 40% of the seeds were empty. However, the results of the control as well as other... parameters of seed germination clearly point to the fact that practically no deep embryo dormancy was observed, but the seed is recalcitrant and microbiotic. The results indicate a non-invasive character of the species in terms of reproductive potential.
