Abstract

Kod odabranih svojti rodova Cotoneaster Ehrh., Kolokwitzia Graebn., Lonicera L., Viburnum L. i Weigela Thunb. u Botaničkom vrtu Prirodoslovno-matematičkog fakulteta Sveučilišta u Zagrebu praćeno je vrijeme nastupa proljetnih fenofaza, s posebnim naglaskom na fenofazu cvjetanja. Fenološkim motrenjima utvrđeno je da tijekom 2015. godine vrijeme cvjetanja vrsta Cotoneaster acutifolius Turcz., Cotoneaster horizontalis Decne., Cotoneaster melanocarpus Lodd., Cotoneaster rhytidophyllus Rehd. & Wils., Kolkwitzia amabilis Graebn., Lonicera nitida Wils., Viburnum lantana L., i Viburnum opulus L. nije odstupalo od vremena cvjetanja navedenog u literaturi. Vrsta Lonicera morrowii Gray. počela je cvjetati nešto ranije u odnosu na vrijeme cvjetanja zabilježeno u dostupnoj literaturi, što je vjerojatno posljedica iznadprosječno visokih temperatura u mjesecu travnju. Vrijeme cvatnje vrsta Lonicera quinquelocularis Hardw. i Viburnum sargentii Koehne. bilo je znatno ranije nego što je navedeno u literaturi, a razlog tome vjerojatno se nalazi u činjenici da su podaci o vremenu cvjetanja za obje vrste uspoređeni s podacima preuzetima iz njemačke literature te se odnose na nešto drugačije klimatske uvjete. Osim toga, moguće je da su iznadprosječno visoke temperature u travnju rezultirale ranijom cvatnjom. Za svojte Weigela 'Bristol Ruby' i Weigela 'Le Printemps', koje su cvjetale u svibnju, nisu pronađeni literaturni podaci o vremenu cvatnje. Kod promatranih svojti praćena je i duljina cvatnje te je utvrđeno da su najkraće cvjetale svojte Lonicera morrowii Gray., Lonicera quinquelocularis Hardw. i Weigela ꞌLe Printempsꞌ (10 dana), dok je najdulje vrijeme cvatnje zabilježeno za Viburnum lantana (29 dana).

Abstract (english)

Spring phenophases, with special emphasis on flowering time, were monitored in selected species of the genera Cotoneaster Ehrh., Kolkwitzia Graebn., Lonicera L., Viburnum L. and Weigela Thunb. in the Botanical Garden of the University of Zagreb. Phenological observations showed that flowering time of Cotoneaster acutifolius Turcz., Cotoneaster horizontalis Decne., Cotoneaster melanocarpus Lodd., Cotoneaster rhytidophyllus Rehd. & Wils., Kolkwitzia amabilis Graebn., Lonicera nitida Wils., Viburnum lantana L., and Viburnum opulus L. in 2015 didn't differ from the time of flowering reported in the literature. Lonicera morrowii Gray. began to bloom earlier than recorded in the available literature, which is probably result of higher than average temperatures in April. Lonicera quinquelocularis Hardw. and Viburnum sargentii Koehne. flowered much earlier than reported in the literature. This is probably due to the fact that flowering times were compared to the data found in German literature referring to somewhat different climatic conditions. It is also possible that higher than average temperatures in April resulted in early onset of flowering. Data about the time of flowering for Weigela 'Bristol Ruby' and Weigela 'Le Printemps', which bloomed in May, were not found in the available literature. Length of the flowering period was the shortest in Lonicera morrowii Gray., Lonicera quinquelocularis Hardw. and Weigela 'Le Printemps' (10 days), while the longest flowering period had Viburnum lantana (29 days).
