Abstract:V poskusnem nasadu Kmetijskega inštituta Slovenije na Brdu pri Lukovici smo v letu 2008 izvedli poskus kemičnega redčenja cvetov jablane sorte 'Summerred', cepljene na podlago M9. S poskusom smo proučili učinke uporabljenih sredstev za namen redčenja plodičev jablane v ekološki pridelavi. Poskus smo zasnovali po metodi 7 naključnih blokov s 13 obravnavanji: 1. neredčena drevesa (kontrola), 2. ročno redčena drevesa v juniju, 3. 1% NaCl, 4. 1.5% NaCl, 5. 1% CH3COOH, 6. 3% CH3COOH, 7. 3% CaSx, 8. 1% ogrščično olje, 9. 3% ogrščično olje, 10. 3% sončnično olje, 11. 3% sojino olje, 12. 5% dekstrin, 13. emulgator 100 + OCA 30. Sredstva za redčenje so bila z nahrbtno ročno škropilnico aplicirana v fenološki fazi vrh cvetenja. Najmočnejše redčenje smo izzvali z aplikacijo 3% ogrščičnega olja, ki je zmanjšalo končni rodni nastavek na nivo ročno redčenih dreves. Žal je to tretiranje povzročilo dokaj močno rjavost kožice plodov. Statistično značilno redčenje je bilo povzročeno tudi z aplikacijo 1.5% NaCl in 3% sojinega olja, vendar z manjšim vplivom na rjavost plodov.

Title:Chemical thinning of "Summerred" apple fruit (Malus domestica Borkh.) in organic production
Abstract:In 2008, we performed an experiment of chemical blossom thinning on apple variety 'Summerred' grafted on M9 basis in an experimental plantation of Agricultural Institute of Slovenia at Brdo by Lukovica. The focus of the experiment was to examine the effects of different chemical thinners used on apple’s fruitlets in organic production. The experiment was conceived on the method of 7 randomized block designs with 13 treatments: 1. unthinned trees (as a control), 2. hand thinned trees in June, 3. 1% NaCl, 4. 1.5% NaCl, 5. 1% CH3COOH, 6. 3% CH3COOH, 7. 3% CaSx, 8. 1% rape oil, 9. 3% rape oil, 10. 3% of sunflower oil,11. 3% soybean oil, 12. 5% dextrin, 13. emulsifier 100 + OCA 30. Chemical thinners were applied in a phenological stage at peak flowering with a manual knapsack sprayer. The best thinning of fruitlets, similar to hand thinned trees, was observed when 3% rape oil was applied. Relatively strong russeting of fruit skin was observed at this treatment. Statistically significant reduced final fruit set also occurred when 1.5% NaCl and 3% soybean oil were sprayed, but with less fruit russeting.
