20.500.12556/DKUM-47894 VPLIV UPORABE RASTNIH HORMONOV V RAZLIČNIH RAZVOJNIH FAZAH PLODOV NA KOLIČINO IN KAKOVOST PRIDELKA ČEŠNJE (Prunus avium L.) IMPACT OF GROWTH REGULATORS, USED IN DIFFERENT STAGE OF FRUIT DEVELOPEMENT, ON QUANTITY AND QUALITY OF THE YIELD (Prunus avium L. V letu 2008 smo v Sadjarskem centru Maribor – Gačnik spremljali vpliv uporabe rastnih hormonov v različnih razvojnih fazah plodov na količino in kakovost pridelka češnje (Prunus avium L.). Namen poskusa je bil ugotoviti, ali rastni hormoni (avksini, citokinini) lahko pri češnji vplivajo na kakovost, velikost in na količino pridelka. Vključenih je bilo 6 obravnavanj, od katerih so 3 obravnavanja predstavljala tretiranje z avksini (Amid-thin, Maxim), 1 obravnavanje s citokinini (CPPU), 1 obravnavanje s kombinacijo avksina in citokinina (Maxim + CPPU) in 1 obravnavanje je predstavljala kontrola. Rezultati so pokazali, da je debelina premera plodu najhitreje naraščala pri obravnavanju z uporabo avksinov (Amid-thin), vendar končni premer plodu ni presegel končne debeline premera plodu pri kontrolnem obravnavanju. Najvišji pridelek (kg/drevo) je bil dosežen pri obravnavanju s kombinacijo avksina in citokinina (Maxim + CPPU). Največje število plodov smo dosegli v obravnavanju z avksini (Amid-thin). Pri masi 100 plodov je obravnavanje s citokinini (CPPU) doseglo najboljši rezultat, vendar dosežena vrednost v primerjavi s kontrolonim ni bila presežena. In 2008, the Fruit-growing center Maribor - Gačnik monitored the impact of the use of growth hormones in various stages of development of the fruit on the quantity and quality of the yield of cherries (Prunus avium L.). The purpose of the experiment was to determine whether growth hormones (auxins, cytokinins) can impact the quality and quantity of cherry (Prunus avium L.) yield. 6 treatments were included. Auxins (Amid-thin, Maxim) were used in 3 treatments, cytokinin (CPPU) in 1 treatment and a combination of auxin and cytokinin also in 1 treatment. In the 6th - control treatment no growth hormones were used. The results show that the fastest increasing of the single fruit diameter was reached at treatment with auxin (Amid-thin), old ought the final diameter of the fruits in this treatment did not exceed the diameter reached at control treatment. The highest yield (kg/tree) has been reached at the treatment with a combination of auxins and cytokinins (Maxim + CPPU). The highest number of fruits we have reached in the treatment with auxin (Amid-thin). The highest weight of 100 fruits has been achieved at treatment with cytokinin (CPPU). Comparing the achieved results with the control treatment, the results of control treatment were not exceeded. češnje Regina rastni hormoni pridelek kakovost cherry regina growth hormones yield quality true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2015-04-22 11:44:26 2015-05-08 14:22:03 2022-05-23 03:06:52 2021-05-07 03:18:02 2015 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:B0ZYV02Q VS_Pelc_David_2015.pdf VS_Pelc_David_2015.pdf 1 F43EAD60BE28CE811D2D374F6597F7E9 e49361d81caa1a11d6f1f375d6f5f4b325a88f71e12e2a6d1e3a8ea7c88e7968 9d439750-7c0b-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=71422 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
