20.500.12556/DKUM-74034 Vpliv cepljenja treh kultivarjev paradižnika na pridelek in kakovost ter odpornost na krompirjevo plesen Influence of grafting on yield, yield quality, and resistance to late blight in three tomato cultivars V letu 2018 smo na posestvu UKC Pohorski dvor izvedli poskus cepljenja treh kultivarjev paradižnika (Benatar F1, Moneymaker in Arletta F1) na komercialno podlago 'TOR 9055 F1'. Uporabili smo tehniko cepljenja v razkol. Ocenjevali smo uspešnost cepljenja, vpliv le-tega na količino in kakovost pridelka (primernost za prodajo) štirih obiranj ter odpornost na krompirjevo plesen. Okuženost listov s krompirjevo plesnijo smo ocenjevali v odstotkih okužene listne površine. Uspešnost cepljenja je bila pri vseh treh kultivarjih nad 90 %, pri cv. Arletta F1' in cv. Moneymaker tudi nad 95 %. Analiza podatkov, pridobljenih pri tehtanju in ocenjevanju primernosti pridelka za prodajo, je pokazala, da cepljenje ni imelo statistično značilnega vpliva na pridelek in kakovost in da interakcija (K × C) ni statistično značilna. Značilen vpliv na količino pridelka in primernost za prodajo je imel le dejavnik kultivar. Tako smo največji skupni pridelek vseh obiranj zabeležili pri cv. Arletta F1 (15.637,9 kg/ha) in najmanjšega pri cv. Benatar F1 (8.580,2 kg/ha). Tudi na okuženost rastlin s krompirjevo plesnijo je imel statistično značilen vpliv le dejavnik kultivar. Najbolj okužen je bil v povprečju cv. Benatar F1 (61,1 %), sledil je cv. Arletta F1 (52,5 %), najmanjši odstotek okužbe pa smo zabeležili na listih sorte Moneymaker (42,7%). In 2018, a grafting experiment using three different tomato cultivars ('Benatar F1', 'Moneymaker', and 'Arletta F1') and the commercial rootstock 'TOR 9055 F1' was conducted at the Pohorski dvor Agricultural Centre of the University of Maribor. The grafting method applied was cleft grafting. The success and influence of grafting on the quality and the fruit yield of four harvests, as well as on the resistance to potato blight were evaluated. The infection magnitude on leaves was evaluated in percentage of infected leaf area. A grafting success rate of above 90% was observed in all three cultivars, in cv. Arletta F1 and cv. Moneymaker the rate was even higher than 95%. The analysis of data obtained from weighing and assessing the saleability of the product showed, that grafting and interaction cultivar and grafting (K × C) had a statistically non-significant effect on fruit yield or quality thereof. Only the cultivar showed a statistically significant impact on fruit yield and its saleability. The highest total fruit yield of all harvests was recorded in cv. Arletta F1 (15,637.9 kg/ha) and lowest in cv. Benatar F1 (8,580.2 kg/ha). The same conclusions can also be made regarding potato blight: only the cultivar had a statistically significant effect on the magnitude of infection. Cv. Benatar F1 (61.1%) was, on average, the most infected, followed by cv. Arletta F1 (52.5%). Cv. Moneymaker displayed the lowest percentage of leaf infection (42.7%). paradižnik cepljenje pridelek kakovost pridelka krompirjeva plesen Tomato Grafting Yield Yield Quality Late blight true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-07-24 11:03:23 2019-08-02 10:33:45 2022-08-09 08:04:53 2019-08-07 03:12:01 2019 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:HUZ15LPR UN_Gomilsek_Gasper_Izidor_2019.pdf UN_Gomilsek_Gasper_Izidor_2019.pdf 1 E08129C74C81A4919549DA9639DE2B05 9af145534795774ba27396a578ae1094fbccd1b6fa8091875ac82fc111fd76b3 cdda14fd-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/058d9cef-cae6-4d66-967f-8b3fc0e93d98 https://dk.um.si/Dokument.php?lang=slv&id=135525 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
