20.500.12556/DKUM-9979 Uporaba proheksadion-Ca pri hruškah (Pyrus communis L.) sorte Viljamova Use of prohexadione Ca in pears (Pyrus communis L.) of Williams variety Na posestvu Fakultete za kmetijstvo in biosistemske vede v Mariboru smo v letu 2003 preučevali vpliv rastnega regulatorja proheksadion-Ca (pripravek Regalis®) na parametre rasti in rodnosti hrušk (Pyrus communis L.) sorte Viljamova. V poskus je bilo vključenih 196 dreves, ki so bila razdeljena na šest obravnavanj. Obravnavanja so predstavljala različen čas in odmerek Regalisa. Obravnavanje 1: kontrola – netretirana drevesa; obravnavanje 2: 1 x 1 kg/ha Regalisa med cvetenjem + 1 x 2 kg/ha po obiranju; obravnavanje 3: 1 x 1 kg/ha Regalisa med cvetenjem + 1 x 1 kg/ha po obiranju; obravnavanje 4: 2 x 1 kg/ha Regalisa med cvetenjem + 1 x 1 kg/ha po obiranju; obravnavanje 5: 3 x 1 kg/ha Regalisa med cvetenjem in po cvetenju + 1 x 1 kg/ha po obiranju; obravnavanje 6: 3 x 1 kg/ha Regalisa med in po cvetenju. Rezultati kažejo, da se je vpliv Regalisa pokazal kot trend manjšanja bujnosti rasti in preprečevanja odpadanja plodov pri hruški, vendar je njegov vpliv nekonsistenten. Razlog za tak podatek je v izjemno močni suši tekom cele vegetacije ter v močnem pojavu hruševega ožiga (Erwinia amylovora). In the year 2003 we were studying influence of growth regulator prohexadione-Ca (called Regalis®) on growth and fruitfulness parameters of pears (Pyrus communis L.) of Williams variety. The experiment took place on property of Faculty of agriculture and Life Science in Maribor. In the experiment we included 196 trees which were divided into six treatments, representing different combinations of Regalis dosage and numbers of treatments. Treatments were: treatment 1: control – non treated trees; treatment 2: 1 x 1 kg/ha of Regalis – sprayed during blossom + 1 x 2 kg/ha sprayed after picking; treatment 3: 1 x 1 kg/ha – sprayed during blossom + 1 x 1 kg/ha after picking; treatment 4: 2 x 1 kg/ha Regalis – sprayed during blossom + 1 x 1 kg/ha after picking; treatment 5: 3 x 1 kg/ha Regalis - sprayed during and after blossom + 1 x 1 kg/ha after picking; treatment 6: 3 x 1 kg/ha Regalis - sprayed during and after blossom. The unconsistent effect of Regalis showed declining trend in reduction of lushness and prevention of fruit drop at pears. Reasons for such results were extremely dry season during vegetation and outburst of fire blight. hruška / rast / rodnost / giberelini / proheksadion-Ca / pear / growth / fruitfulness / gibberellins / prohexadione-Ca true true false Slovenski jezik Angleški jezik Diplomsko delo 2009-03-17 19:10:03 2009-04-06 10:27:34 2022-04-11 15:53:59 2022-04-15 03:31:47 2009 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:A59LE8A5 VS_Popovski_Dusan_2009.pdf VS_Popovski_Dusan_2009.pdf 1 8E877C20EF0F0481736E9490FE7D0754 6dd4f5cbb08d31223e7571028963c3d2db9f73536587ed5fc5e189ae8ad4f70f afab5159-7c02-11eb-bb7a-00155d0001ca 20.500.12556/dkum/5f1af16a-32c1-4a1e-86bb-bed84c985996 https://dk.um.si/Dokument.php?lang=slv&id=7841 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
