Abstract

U radu je analizirana fenologija cvatnje proljetnica na dva lokaliteta na području grada Zagreba, park-šumi Maksimir i park-šumi Jelenovac. Istraživanja su provedena 2016. godine, a bilježeni su datumi početka cvatnje, pune cvatnje, početka senescencije cvjetova i kraja cvatnje. Na oba je lokaliteta već početkom veljače počela cvjetati vrsta Primula vulgaris Huds., a ubrzo je procvjetala i vrsta Tusillago farfara L. na lokalitetu Maksimir. U prvoj polovici veljače cvatnja je zatim nastupila i redom kod vrsta Pulmonaria officinalis L., Crocus vernus (L.) Hill., Galanthus nivalis L., Leucojum vernum L. i Hacquetia epipactis (Scop.) DC. U drugoj polovici veljače počele su cvjetati vrste Helleborus dumetorum Waldst. et Kit., Corydalis solida (L.) Swartz, Corydalis bulbosa (L.) Ker.-Gawl., Erythronium dens-canis L., Anemone nemorosa L. i Viola odorata L. Najkasnije, oko sredine ožujka, procvjetale su vrste Lathraea squamaria L., Oxalis acetosella L. i Gagea lutea (L.) Ker.-Gawl. Usporedbom vremena cvatnje s literaturnim podacima utvrđeno je da je prije razdoblja cvatnje navedenog u literaturi počelo cvjetati čak devet vrsta, dok su ostale vrste procvjetale na početku razdoblja cvatnje navedenog u literaturi. Najveće odstupanje od literaturnih podataka pokazale su vrste Gagea lutea, Hacquetia epipactis i Oxalis acetosella kod kojih je cvatnja završila prije početka razdoblja cvjetanja navedenog u literaturi. Vrlo rani početak cvatnje proljetnica u istraženim park-šumama u odnosu na literaturne podatke može se pripisati iznadprosječno visokim temperaturama zraka u siječnju i veljači.

Abstract (english)

In this work, flowering phenology of spring ephemerals was analysed at two sites in Zagreb, forest-park Maksimir and forest-park Jelenovac. The study was conducted in 2016., and the dates of the beginning of flowering, full flowering, the beginning of flower senescence and the end of flowering were recorded. On both sites, Primula vulgaris Huds. started to flower in early February, followed by Tusillago farfara L. in Maksimir. Thereafter, Pulmonaria officinalis L., Crocus vernus (L.) Hill., Galanthus nivalis L., Leucojum vernum L. and Hacquetia epipactis (Scop.) DC. started to flower, still in the first half of February. Helleborus dumetorum Waldst. et Kit., Corydalis solida (L.) Swartz, Corydalis bulbosa (L.) Ker.-Gawl., Erythronium dens-canis L., Anemone nemorosa L. and Viola odorata L. flowered in the second half of February. Finally, Lathraea squamaria L., Oxalis acetosella L. and Gagea lutea (L.) Ker.-Gawl. flowered around mid-March. Comparison of the times of flowering with literature data showed that nine species started to bloom earlier than indicated in the literature, while flowering of other species occurred at the beginning of flowering time found in the literature. Gagea lutea, Hacquetia epipactis and Oxalis acetosella showed the largest difference from the literature data: for these species flowering ended before the beginning of the period of flowering indicated in the literature. Very early flowering of spring ephemerals at investigated sites may be attributed to higher than average air temperatures in January and February.
