Abstract

Prilikom odabira ukrasne dendroflore važno je poznavati početak i trajanje fenoloških faza u određenim klimatskim uvjetima. Kod drvenastih vrsta s dekorativnim cvjetovima osobitu važnost ima fenofaza cvatnje. U okviru rada su 2016. godine u 7 parkova Zelene potkove u Zagrebu praćene proljetne fenofaze 13 drvenastih svojti koje cvjetaju tijekom proljeća. Za svaku svojtu praćena je fenofaza listanja (početak listanja i potpuno razvijeni listovi) i fenofaza cvatnje (početak, vrhunac i završetak cvatnje). Dobiveni podaci o vremenu cvatnje uspoređeni su s dostupnim literaturnim podacima te analizirani s obzirom na vrijednosti temperature zraka u razdoblju koje je prethodilo cvatnji. Kod tri svojte cvatnja je započela ranije nego što se navodi u literaturi, što je vjerojatno posljedica iznadprosječno visokih temperatura u razdoblju koje je prethodilo cvatnji (posebice u veljači). Vrijeme cvatnje ostalih svojti nije odstupalo od vremena cvatnje navedenog u literaturi.

Abstract (english)

When choosing ornamental trees and shrubs, it is important to know the beginning and duration of phenological phases in local climate conditions. In flowering trees and shrubs, flowering phenophase is of particular significance. In this work, spring phenophases of 13 woody ornamental species were studied in 7 parks of Zelena potkova in Zagreb, in 2016. For each selected taxon, leafing phenophase (the beginning of leafing and completely developed leaves) and flowering phenophase (the beginning of flowering, full flowering and the end of flowering) were monitored. The time of flowering were compared to the literature data and analyzed with regard to the temperatures in the period before flowering. Three species started to flower earlier than found in the literature, which was likely result of above than average temperatures in the period that preceded flowering (especially in February). Flowering time of other species did not differ from the data found in the literature.
