The impact of rooting preparations on the growth and development of \u27Welschriesling\u27 grafts

V letih 2012 in 2013 smo pri sorti \u27Laški rizling\u27 ugotavljali vpliv različnih pripravkov za okoreninjenje na rast in razvoj cepljenk v prvem in drugem letu po sajenju v vinogradu. Spremljali smo fenološke faze, prirast mladik, intenziteto zelene barve listov z N-testerjem, masi sveže in suhe snovi enoletnega lesa rozg, maso grozdja in kemijski sestav grozdnega soka. Za spodbujanje rasti korenin sta bila uporabljena pripravka Magic P+Algaren in Pralumus. Pri pripravku Pralumus je bila intenziteta zelene barve listov statistično značilno večja kot pri Kontroli (p≤0,05). Na rastišču z večjo vsebnostjo organske snovi v tleh je bilo največ suhe snovi lesa rozg pri pripravku Pralumus (p≤0,05). Parametri pridelka se med obravnavanji niso statistično značilno razlikovali (p≤0,05).In 2012 and 2013 tests on the impact of rooting preparations on ‘Welschriesling’ graft’s growth and development after the first and second planting year, have been undertaken. Phenological phases, growth of shoots, the green colour intensity of leaves measured via an N-tester, the mass of fresh and dry substance of canes, grape mass and the chemical composition of grape juice have been monitored. The preparations used were Magic P + Algaren and Pralumus. When using the Pralamus preparation the intensity of the green colour in the leaves was significantly higher than the one in Kontrola (p<0,05). The site which was treated with Pralumus (p
