Abstract

U radu su prikazani rezultati praćenja tijeka senescencije i apscizije listova u 14 ukrasnih
drvenastih svojti u širem središtu grada Zagreba u jesen 2016. godine. Promjena boje listova
je kod najvećeg broja istraženih svojti nastupila u rujnu, a završila u listopadu i studenom. Na
senescenciju listova snažno je utjecala svjetlost: kod 7 svojti su boju brže mijenjali listovi na
krošnjama ili dijelovima krošnji na osunčanijim položajima, a samo je kod 3 istražene svojte
promjena boje prije započela na dijelovima krošnje koji su tijekom većeg dijela dana bili
zasjenjeni. Kod 8 svojti su listovi najprije počeli mijenjati boju u vanjskom dijelu krošnje, a
kod 5 svojti u unutrašnjem. Listovi su u većine svojti počeli otpadati u listopadu te su stabla
uglavnom sasvim ogoljela u studenom i prosincu. Do nagle promjene boje i bržeg otpadanja
listova kod većine je svojti došlo nakon naglog pada temperature praćenog obilnim oborinama
krajem listopada i početkom studenog.

Abstract (english)

This research shows results of monitoring leaf senescence and abscission in 14 ornamental
tree species in wider center of Zagreb during the Fall 2016. Leaf colour change began in
September, and completed during October and November. Leaf senescence was strongly
influenced by light: sun-exposed crowns or parts of the crowns changed colour faster in 7
species, while in 3 species this process started earlier in the parts of a crown that were shaded
during most of the day. Leaves in the inner part of a crown started to change colour earlier in
8 species, while leaves of the outer part of a crown changed colour earlier in 5 species. In
most species, leaf abscission started in October, and finished during November or December.
Rapid colour change and leaf fall occurred after the sudden decline in temperature followed
by heavy precipitation during the late October and early November.
