20.500.12556/DKUM-71631 VPLIV MIKROBIOLOŠKIH PRIPRAVKOV NA RAST ORHIDEJ IZ RODU Phalaenopsis sp. The effects of microbiological inoculants on the growth of phalaenopsis orchids Tehnologija efektivnih mikroorganizmov (EM, angl. effective microorganisms) uporablja kombinacijo več vrst kultur živih mikroorganizmov, ki so bili izolirani iz naravnih rodovitnih tal. Namen diplomskega dela je proučiti vpliv uporabe koristnih mikroorganizmov (EM-tehnologije) na električno prevodnost in pH-vrednost izcedka hranilne raztopine ter morfološke lastnosti orhidej iz rodu falenopsis. V raziskavo, ki je potekala v podjetju Ocean Orchids, d. o. o., smo vključili štiri sorte orhidej rodu falenopsis ('Brisbane Anthura', 'Anthura Cambridge', 'Anthura Montreux' ter 'Anthura Washington'). Uporabili smo tri različna EM-sredstva (EM Multy Grower®, EM Naturalny Aktiwny® in EM-5®). Uporaba mikrobioloških pripravkov je značilno znižala povprečno vrednost električne prevodnosti izcedka hranilne raztopine in njegovo pH-vrednost le pri sorti 'Anthura Cambridge'. Prav tako je uporaba EM-pripravkov značilno vplivala na določene morfološke lastnosti rastlin, vendar je bil učinek odvisen od sorte. Pri sorti 'Anthura Cambridge' se je značilno znižala sveža masa listov. Pri sortah 'Brisbane Anthura' in 'Anthura Washington' je uporaba EM-pripravkov značilno znižala vsebnost suhe snovi korenin, pri sortah 'Anthura Cambridge' in 'Anthura Montreux' se je značilno znižala suha snov listov. The Effective Microorganisms-technology (EM) uses a combination of several species of living microorganism cultures that were isolated from a natural fertile soil. The aim of this diploma paper is to examine the influence of the use of useful microorganisms (EM technology) on electrical conductivity and pH value of the nutrient solution exodate, and on morphological properties of Phalaenopsis orchids. In the research that took place at the Ocean Orchids d. o. o. company, we included four varieties of Phalaenopsis orchids ('Brisbane Anthura', 'Anthura Cambridge', 'Anthura Montreux', and 'Anthura Washington'). We used three different EM agents (EM Multy Grower®, EM Naturalny Aktiwny® and EM-5®). The treatment with EM preparations significantly increased the mean value of electrical conductivity of the nutrient solution exodate and decreased its pH in the 'Anthura Cambridge' variety only. In addition, the treatment significantly influenced certain morphological properties of plants, however, the effect was variety dependent. In the ‘Anthura Cambridge’ the treatment with EM significantly reduced leaves fresh weight. In the ‘Brisbane Anthura’ and ‘Anthura Washington’ varieties, the treatment with EM preparations significantly reduced the roots dry matter. In the ‘Anthura Cambridge’ and ‘Anthura Montreux’ varieties significantly lower values of dry matter of leaves was observed. koristni mikroorganizmi Phalaenopsis sp. rast morfološke lastnosti effective microorganisms Phalaenopsis sp. growth morphology true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2018-08-24 08:37:33 2018-08-31 11:39:30 2022-08-01 21:15:09 2019-07-11 18:49:14 2018 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:REJUSO5F VS_Lichteneger_Nika_2018.pdf VS_Lichteneger_Nika_2018.pdf 1 2626EA9B644EB00F33857A492DC45FC6 1d9b3f4cb1ab78b54a791abed3dcfce686073391dedf31abefe5b341be82f92a 3433d201-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/75940033-cb9d-4593-ab08-26475069753c https://dk.um.si/Dokument.php?lang=slv&id=127863 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
