20.500.12556/DKUM-17918 SPREMLJANJE MORFOLOŠKIH IN BIOKEMIČNIH LASTNOSTI VERBEN OB TRETIRANJU Z IZVLEČKOM RJAVIH ALG Monitoring morphological and biochemical characteristics of vervains during the treatment with brown sea algae extract Verbene so priljubljene enoletnice, primerne za zasaditve balkonskih korit, cvetličnih gred in grobov. Verbene najpogosteje razmnožujemo vegetativno, s potaknjenci. Namen diplomskega dela je bil ugotoviti, vpliv izvlečka alg Ecklonia maxima (Kelpak, Kelp Products) na nekatere morfološke in biokemične lastnosti potaknjencev verben (Verbena hybrida 'Ipanema blue'). V poskusu smo rastline talno tretirali s tremi vodnimi raztopinami Kelpaka (2 %, 1 %, 0,5 % in 0 %) v dveh terminih, in sicer pred potikanjem v gojitvene plošče (1. 4. 2008) in tri tedne kasneje. Ob 2. in 3. vzorčnem terminu, so imele rastline tretirane z 1 % in 2 % vodno raztopino Kelpaka statistično več skupne biomase, nadzemna in podzemna biomasa se prav tako povečata, razmerje med njima pa narase v primerjavi s kontrolo. Ob zadnjem vzorčnem terminu, za časa tržne zrelosti smo pozitivno prirast nadzemnega dela določili pri 0,5 % in 1 % raztopini Kelpaka, vendar trend ni več signifikanten. Pri biokemičnih lastnosti smo se osredotočili na vsebnost skupnih proteinov in fenolov ob dveh vzorčnih terminih (2. 4. 2008 in 24. 4. 2008). Tretiranje verben s Kelpakom v koncentracijah 0,5 % in 1 % pozitivno vpliva na vsebnost skupnih proteinov, saj smo v obeh vzorčnih terminih izmerili povišane vrednosti v primerjavi s kontrolo, ki pa se signifikantno odražajo le pri prvem vzorčnem terminu. Pri analizi vsebnosti skupnih fenolov v listih verben smo signifikantni učinek zabeležili pri 1% koncentraciji Kelpaka. Na podlagi rezultatov poskusa lahko zaključimo, da 1 % vodna raztopina Kelpaka pri talni aplikaciji skupno najbolje vpliva na morfološke in biokemijske lastnosti verben. Vervains are popular annuals appropriate for growing on balconies and windows, flower beds and graves. They are usually propagated vegetatively, by cuttings. In the presented study, the impact of the brown algae (Ecklonia maxima) extract (Kelpak, Kelp Products) on some morphological and biochemical characteristics of vervain cuttings (Verbena hybrida »Ipanema blue«) was investigated. The cuttings were treated with three aqueous solutions of Kelpak (2 %, 1 %, 0,5 % in 0 %) twice, namely before placing the cuttings in multiplates (1. 4. 2008) and three weeks later (24. 4. 2008). At the second and third sampling date, the plants treated with 1 % or 2 % of Kelpak solution produced more biomass. The aboveground and underground biomass rose and the proportion between them increased when compared with the untreated plants. At the last sampling date, when the plants reached the market value, the positive increase in the aboveground weight was noticed when using 0,5 % and 1% of algae solution, although the trend was insignificant. When identifying biochemical characteristics, we focused on the total protein and phenolic contents in leaves at two sampling dates (2. 4. 2008, 24. 4. 2008). Both 0,5 % and 1 % Kelpak treatment had a positive impact on the total protein contents. At the first sampling date, significantly increased values were detected at 1 % Kelpak concentration when compared to the untreated plants. By means of the research, we identified significant alterations in total phenolic contents in the vervain leaves 24 hours after 1 % Kelpak treatment. Based on the presented results, we can conclude that soil application of 1 % Kelpak had the most desired influence on morphological and biochemical characteristics of vervains. indol-3-maslena kislina Kelpak skupni proteini skupni fenoli Verbena hybrida 'Ipanema blue' indole-3-butyric acid Kelpak total proteins total phenolics Verbena hybrida 'Ipanema blue' true true false Slovenski jezik Angleški jezik Diplomsko delo 2011-03-30 11:42:55 2011-04-01 10:36:37 2022-04-13 10:16:11 2023-12-23 03:14:12 2011 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:S3VACZWV UNI_Petek_Andreja_2011.pdf UNI_Petek_Andreja_2011.pdf 1 1178B28732EC776C39CC99D725D9163B f8a179c85286dacf9a28c65691f4d1d06d3360e6e4f3f77a5a5b6c25442199fd 0157f6a0-7c05-11eb-bb7a-00155d0001ca 20.500.12556/dkum/72782ff8-2f6e-4bb5-bdbf-9b5955e8f899 https://dk.um.si/Dokument.php?lang=slv&id=21150 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
