20.500.12556/DKUM-59958 VPLIV RASTNEGA REGULATORJA CCC NA VEGETATIVNI IN REPRODUKTIVNI RAZVOJ VINSKE TRTE (Vitis vinifera L.) THE INFLUENCE OF GROWTH REGULATOR CCC ON VEGETATIVE AND REPRODUCTIVE DEVELOPEMENT OF GRAPEVINE (Vitis vinifera L.) V letu 2004 smo ugotavljali vpliv rastnega regulatorja cikocel (CCC) na vegetativni in reproduktivni razvoj pri sortah 'Renski rizling', 'Sauvignon', 'Rumeni muškat', 'Chardonnay' in 'Modri pinot'. Pri vseh sortah smo ugotavljali število grozdov in maso grozdov (g) na trs, število jagod, maso jagod (g) in maso pecljevine na grozd (g), maso sto jagod (g), število pečk in maso pečk na sto jagod ter vsebnost sladkorja (°Oe). Vsebnost sladkorja smo merili po tretjinah grozda, pri peclju, v sredini grozda in na vrhu grozda. Vpliv CCC na vegetativni razvoj smo ugotavljali z merjenjem dolžine internodijev od 1. do 6. internodija, od 6. do 11. internodija ter od 11. do 16. internodija. Rezultati so pokazali, da uporaba rastnega regulatorja CCC vpliva na vegetativno rast. Pri trikratni uporabi CCC se je izrazito zmanjšala dolžina internodijev, na mehansko sestavo grozdja pa ni imel pomembnega vpliva. Z enkratno uporabo CCC smo vplivali na zvišanje sladkorja, z dvakratno in s trikratno pa na znižanje sladkorja v grozdnem soku. In 2004, the influence of growth regulator cycocel (CCC) on vegetative and reproductive development on wine varieties 'Rhine Riesling', 'Sauvignon', 'White Muscat', 'Chardonnay' and 'Pinot noir' were determined. For all varieties, we measured the number of grapes and the mass of the grapes (g) per vine, the number of berries, the mass of the berries (g) and rachis (g), the mass of one hundred berries (g), the number and the mass of the seeds per one hundred berries and the sugar content (°Oe). The sugar content was measured by the thirds of the grape, at the stem, in the centre of the grape, and at the top of the grape. The influence of CCC on vegetative development was determined by measuring the length of the internodes from the 1st to the 6th internode, from the 6th to the 11th internode, and from the 11th to the 16th internode. The results showed that the use of growth regulator CCC had an effect on vegetative growth. The length of the internodes had been significantly reduced with the three times used CCC, however it did not have an important effect on the mechanical composition of the grape. Single use of CCC caused the increase of sugar content, but two and three-time use caused a decrease of sugar content in the grape juice. vinska trta rastni regulatorji CCC 'Renski rizling' 'Rumeni muškat' 'Chardonnay' 'Sauvignon' 'Modri pinot' grapevine growth regulator CCC 'Rhein Riesling' 'White Muscat' 'Chardonnay' 'Sauvignon' 'Pinot noir' true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-06-02 18:49:51 2016-10-11 07:07:31 2022-06-22 03:05:15 2019-07-11 11:31:00 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:GBEJBFT3 UN_Mulec_Dusan_2016.pdf UN_Mulec_Dusan_2016.pdf 1 1D4BF447B84447BC5ABB77E467CD823B 773875a313ba98bc7f7b2641a364f4153d32f9cc2451040eb7b87010c067125d a365f3b4-7c0c-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=93607 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
