Zdravstveno stanje drvenastih i žbunastih vrsta Topčiderskog parka

Abstract

Tokom istraživanja izvršena je procena zdravstvenog stanja drvenastih i žbunastih vrsta prirodnog dobra Topčiderski park na osnovu utvrđene vizuelne ocene, stepena defolijacije i dekolorizacije. Tokom vegetacijskog perioda 2018-2019 utvrđeno je zdravstveno stanje biljnih vrsta iz 50 rodova. Vrste koje su okarakterisane kao zdrave, bez vidljivih oštećenja su: Cedrus atlantica, Corylus avelana, C. colurna, Juglans nigra, Maclura aurantiaca, Mahonia aquifolium, Prunus cerasifera, P. spinosa, Quercus rubra i Sambucus nigra. Stabla sa izraženim povredama su: Acer negundo, A. pseudoplatanus, Aesculus hippocastanum, Cryptomeria japonica, Fagus moesiaca, Gleditsia triacanthos, Morus alba, Platanus acerifolia, Populus alba. P. nigra, P. tremula. Stabla u odumiranju i potpuno mrtva stabla nisu zabeležena u parku Topčider. Najugroženije biljne vrste od napada patogenih gljiva i gljivama sličnih organizama su vrste javora, divlji kesten, vrste lipa, topola i platan. Prisutne vrste insekata i grinja nisu u značajnijoj meri uticale na zdravstveno stanje istraživanih biljnih vrsta.

The research deals with the health condition of tree and shrub species of the natural resource known as Topčider Park assessed on the basis of the conducted visual assessment and determination of the degree of defoliation and discolouration. During the growing season 2018-2019, the health condition of plant species belonging to 50 different genera was determined. The following species were found to be healthy, without any visible damage: Cedrus atlantica, Corylus avelana, C. colurna, Juglans nigra, Maclura aurantiaca, Mahonia aquifolium, Prunus cerasifera, P. spinosa, Quercus rubra and Sambucus nigra. Trees with visible injuries included: Acer negundo, A. pseudoplatanus, Aesculus hippocastanum, Cryptomeria japonica, Fagus moesiaca, Gleditsia triacanthos, Morus alba, Platanus acerifolia, Populus alba. P. nigra, and P. tremula. Dying trees and dead trees were not recorded in Topčider Park. The plant species most threatened by the attack of pathogenic fungi and fungus-like organisms were the species of maple, horse chestnut, lime, poplar, and plane. The species of insects and mites here present did not significantly affect the health status of the investigated plant species.
