20.500.12556/DKUM-78575 Pestrost opraševalcev v ekološkem nasadu jablan The Diversity of Pollinators in Apple Orchard V raziskovalnem delu smo aprila 2019 raziskovali pestrost čebel v ekološkem nasadu jablan (Malus domestica B.) Fakultete za kmetijstvo in biosistemske vede Maribor na sorti 'Topaz'. Ob ugotavljanju pestrosti smo merili še številčnost čebel in njihovo aktivnost v neposredni povezavi z vremenskimi okoliščinami. Vzorčenje smo opravljali tri zaporedne dneve s pomočjo lovljenja v plastične vrečke, v dveh 90-minutnih intervalih na dan med 9.00 in 16.00 uro. Hkrati nas je zanimalo tudi, ali čebele pritegne specifična barva, za kar smo se poslužili metode lovljenja z barvnimi krožniki. Rezultati raziskave so pokazali, da je številčno prevladovala medonosna čebela (Apis mellifera), skoraj enakovreden delež opraševanja pa so predstavljale tudi divje čebele. Temperatura zraka ni pokazala večjega vpliva na številčnost čebel. Rumena barva je bila za čebele najzanimivejša. V vabe te barve se je ulovilo največje število opraševalcev in največje število različnih vrst čebel. In April 2019, the bee diversity in organic apple orchards (Malus domestica B.) of the Topaz variety was investigated at the Faculty of Agriculture and Life Sciences in Maribor. In determining the diversity, the number of bees and their activity in direct connection with weather conditions were also measured and observed. Sampling was performed for three consecutive days by trapping the bees in plastic bags, at two 90-minute intervals per day between 9 a.m. and 4 p.m. At the same time, we were also interested in whether the bees are attracted to a specific color, for which we used the method of hunting with colored plates. The results of the research showed that the number of honey bees (Apis mellifera) was predominant, and wild bees also represented an almost equal share of pollinators. Air temperature did not show a major effect on bee numbers. The yellow color was the most interesting for the bees. The baits of this color are chosen by the largest number of pollinators and the largest number of different species of bees. opraševanje divji opraševalci jablana medonosna čebela pollination wild pollinators apple tree honeybee true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2021-01-19 14:12:46 2021-03-05 10:16:33 2024-09-04 11:43:37 2021-03-02 03:22:03 2021 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:HC8IV5YH VS_Stuhec_Ana_2021.pdf VS_Stuhec_Ana_2021.pdf 1 CF5911DA43A3BB010366670FA039B980 09394a50938f2b864943acc93703dd0e78ffd0ddfc68d37124fa7926aed1cd3b 16efcc20-7c12-11eb-bb7a-00155d0001ca 20.500.12556/dkum/35782963-48da-4886-8f47-91a399d42237 https://dk.um.si/Dokument.php?lang=slv&id=148558 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
