Uticaj primene polietilenske folije na prijem kalemova oraha (Juglans regia L.) u stratifikali

Abstract

Ispitivan je uticaj primene polietilenske folije na prijem kalemova oraha (Juglans regia L.) u stratifikali. U radu su bila zastupljena adva tretmana: tretman I - kalemljenje sa parafinisanjem spojnog mesta podloge i plemke i stratifikovanje strugotinom do vrha plemke i tretman II - kalemljenje sa parafinisanjem spojnog mesta podloge i plemke, stratifikovanje strugotinom do spojnog mesta i prekrivanje polietilenskom folijom. Primena polietilenske folije uslovila je višu temperaturu strugotine za 1 °C u 2003. godini i za 0,5-1 °C u 2004. godini u odnosu na tretman bez primene folije, što je doprinelo većem prijemu kalemova u tretmanu II za 7,70% nakon dvadeset dana stratifikovanja i za 8,90% nakon dvadesetosam dana stratifikovanja u odnosu na tretman I.

The effect of polyethylene foil on walnut (Juglans regia L.) grafting success under stratification conditions was evaluated in this study involving two grafting treatments: treatment I - dipping the rootstock-scion union into paraffin and stratification in sawdust up to the top of the scion, and treatment II - dipping the rootstockscion union into paraffin, stratification in sawdust up to the graft union and covering with polyethylene foil. The use of polyethylene foil induced an increase in sawdust temperature by 1 °C in 2003 and 0.5-1 °C in 2004, as compared to the treatment without the use of foil, eventually leading to a 7.7% and 8.90% increase in grafting success on day 20 and day 28 after stratification, respectively, in treatment II, as compared to treatment I.
