Adaptivnost Paulownia tomentosa (thumb.) Sieb. et Zucc. na zelenim površinama u Beogradu

Abstract

Za potrebe pejzažne arhitekture i hortikulture su vrlo bitni taksoni sa poboljšanim estetskim svojstvima, povećanom ili smanjenom produktivnošću, povećanom otpornošću na bolesti i insekte, aerozagađenja kao i sa optimalnom adaptivnošću u urbanim cenozama. Jedna od vrsta koja zadovoljava napred iznete kriterijume je Paulownia tomentosa (Thumb.) Sieb. et Zucc. U radu je analizirano više morfo-fizioloških osobina stabala paulovnije koja su odgajena na zelenim površinama Beograda: na Banovom brdu, Dorćolu, Tašmajdanu, Novom Beogradu i Zemunu. Dobijeni rezultati potvrđuju adaptivnost paulovnije na zelenim površinama u Beogradu, ali i potrebu da se otkriju roditeljska stabla sa najboljom kombinatornom sposobnošću u cilju oplemenjivanja i proizvodnje sadnog materijala za potrebe urbanih cenoza, kao i za podizanje namenskih kultura ove vrste.

The taxa with the improved esthetical characteristics, increased or decreased productivity, higher resistance to diseases, insect attacks, air pollution, as well as with optimal adaptability in urban coenoses are of great importance to land­scape architecture, horticulture and forestry. The criteria for the selection of individual plants out of the number of many individuals depend on their future usage, but also on their esthetical features, morphology and physiology. One of the species that fulfils the above criteria is Paulownia tomentosa (Thumb.) Sieb. et Zucc. Different morphophysiological features of royal paulownia cultivated on green areas in Banovo Brdo, Dorćol, Tašmajdan, Novi Beograd and Zemun are analyzed. The study results prove the adaptability of royal paulownia on green areas in Belgrade, but also the need to select the parent trees with the best combining features prior to production, aiming at the improvement and production of planting material for urban coenoses and specific-purpose plantations of this species.
