In the years 2007 and 2008 we performed a grafting experiment on the walnut kind 'Šejnovo' by using different grafting procedures that involve groundings and scions of different thickness, and scions of different length (one-nodal, two-nodal scions). The experiment was carried out in the Žižek tree nursery with the purpose of determining the success of the 'Šejnovo' walnut grafting procedure. The first experiment included 8 different treatments: (1) the mechanical omega 1 system (one-eye) thin scion (O1-T), (2) the mechanical omega 1 system (one-eye) thick scion (O1-D), (3) the mechanical omega 2 system (two-eye) thin scion (O2-T), (4) the mechanical omega 2 system (two-eye) thick scion (O2-D), (5) mechanical lamella thin scion (L-T), (6) mechanical lamella thick scion (L-D), (7) manual thin scion (R-T), (8) manual thick scion (R-D). The second experiment includes 6 different treatments including the mechanical lamella 2 system (two-eye) thin scion (L2-T), mechanical lamella 2 system (two-eye) thick scion (L2-D), manual 2 system (two-eye) thin scion (R2-T), manual 2 system (two-eye) thick scion (R2-D) and excluding the mechanical omega 1 system (one-eye) thin scion (O1-T), the mechanical omega 1 system (one-eye) thick scion (O1-D), mechanical lamella 1 system thin scion (L1-T), mechanical lamella 1 system thick scion (L1-D), manual thin scion 1 system (R1-T), manual thick scion 1 system (R1-D). Based on the obtained results the one-eye omega and lamella grafting procedures were more successful when carried out with thicker scions and groundings (12-16 mm). When using omega grafting procedures with groundings of different thickness we recommend the use of two-nodal scions. For a more reliable production of grafted walnut plants, regardless of the length and thickness of scions and groundings, we recommend the English copulation.

V drevesnici Žižek smo v letih 2007 in 2008 izvedli poskus cepljenja oreha sorte 'Šejnovo', pri tem pa vrednotili razlièno debelino podlag in cepièev ter razlièno dolžino le-teh (eno-nodijski, dvo-nodijski cepiè). V prvi poskus smo vkljuèili 8 razliènih obravnavanj: (1) strojno omega 1 sistem (eno oko) tanki cepiè (O1-T), (2) strojno omega 1 sistem (eno oko) debeli cepiè (O1-D), (3) strojno omega 2 sistem (dve oèesi) tanki cepiè (O2-T), (4) strojno omega 2 sistem (dve oèesi) debeli cepiè (O2-D), (5) strojno lamela tanki cepiè (L-T), (6) strojno lamela debeli cepiè (L-D), (7) roèno tanki cepiè (R-T), (8) roèno debeli cepiè (R-D). V drugi poskus smo vkljuèili 6 razliènih obravnavanj, pri katerem smo dodali strojno lamela 2 sistem (dve oèesi) tanki cepiè (L2-T), strojno lamela 2 sistem (dve oèesi) debeli cepiè (L2-D), roèno 2 sistem (dve oèesi) tanki cepiè (R2-T), roèno 2 sistem (dve oèesi) debeli cepiè (R2-D) in odvzeli strojno omega 1 sistem (eno oko) tanki cepiè (O1-T), strojno omega 1 sistem (eno oko) debeli cepiè (O1-D), strojno lamela 1 sistem tanki cepiè (L1-T), strojno lamela 1 sistem debeli cepiè (L1-D), roèno tanki cepiè 1 sistem (R1-T), roèno debeli cepiè 1 sistem (R1-D). Na podlagi dobljenih rezultatov je uspešnost cepljenja pri omega in lamelnem naèinu cepljenja z enim oèesom veèja ob uporabi debelejših cepièev in podlag (12-16 mm). Pri uporabi omega naèina z razlièno debelino podlag priporoèamo uporabo dvonodijskih cepièev. Za zanesljivo proizvodnjo sadik cepljenega oreha ne glede na dolžino in debelino cepièev ter podlag priporoèamo uporabo angleške kopulacije.
