20.500.12556/DKUM-64208 REDČENJE CVETJA IN PLODIČEV PRI JABLANI (Malus domestica B.) SORTE 'FUJI' THINNING OF FLOWERS AND FRUITLETS IN APPLE TREES (Malus domestica B.) CV. 'FUJI' V nasadu jablan Fakultete za kmetijstvo in biosistemske vede, nasad Pohorski Dvor, smo v letu 2005 izvedli poskus kemičnega redčenja cvetov in plodičev sorte 'Fuji', posajene na šibki podlagi M9. Starost nasada je 6 let. Poskus redčenja smo zastavili v sedmih naključnih blokih z devetimi obravnavanji. 1. Neredčeno, 2. Ročno redčenje junij, 3. Etephon 200 ppm odprt prvi cvet, 4. NAD 100 ppm konec cvetenja, 5. BA 150 ppm debelina plodičev(8-10mm), 6. BA 150 ppm debelina plodičev(13-15mm), 7. Etephon 200 ppm+BA 150 ppm pričetek cvetenja, 8. NAD 100 ppm +BA 150 ppm konec cvetenja, 9. BA 150 ppm debelina plodičev (8-10mm). Poskusna drevesa smo škropili z nahrbtno škropilnico do točke omočenosti. Najmočnejše redčenje smo ugotovili z aplikacijo sredstev Etephon 200 ppm+BA 150 ppm (obravnavanje št. 7), kar se je izrazilo v številu plodov na drevo. Pri ugotavljanju debeline plodov (>70 mm) prvega kakovostnega razreda je statistična razlika BA 150 ppm v kombinaciji pri debelini plodičev 8 do 10 mm. In year 2005 we carried out an experiment of chemical thinning of blossom and fruitlets in the variety ‘Fuji’ at the plantation of apple trees Pohorski Dvor, the property of the Faculty of Agriculture and Life Sciences. The variety is grafted on a weak rootstock M9. The age of the plantation is 6 years. The experiment of thinning was set in seven random blocks with nine treatments. 1. No thinning 2. Hand thinning June 3. Etephon 200 ppm first flower opened, 4. NAD 100 ppm flowering ended, 5. BA 150 ppm thickness of fruitlets (8-10mm), 6. BA 150 ppm thickness of fruitlets (13-15mm), 7. Etephon 200 ppm + BA 150 ppm beginning of flowering, 8. NAD 100 ppm + BA 150 ppm flowering ended, 9. BA 150 ppm thickness of fruitlets (8-10mm). The experimental trees were sprayed with a knapsack sprayer to the point of wetness. The strongest thinning was determined by the application of Etephon 200 ppm + BA 150 ppm which was reflected in the number of fruits per tree. In determining the thickness of the fruits (> 70 mm) in the first quality class, a statistical difference was observed in treatment no. 9 at application of BA 150 ppm in combination in thickness of fruitlets 8 to 10 mm. jablana Fuji kemično redčenje apple tree ”Fuji” variety chemical thinning true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-09-23 13:28:11 2016-10-11 07:10:56 2022-07-04 03:07:29 2019-07-11 13:54:02 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:WAFQYJPN VS_Fajs_Bojan_2016.pdf VS_Fajs_Bojan_2016.pdf 1 9A2A9A94AA39E9E6766AA6731B3F4FA9 dd8c08b48e6f4078227588df3559c22f788bc6cbf773611a7132f90c21cb479c 9faf424c-7c0d-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=106096 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
