Ožiljavanje zrelih reznica smokve (Ficus carica L.)

Abstract

U ovom radu su prikazani rezultati egzogene primjene različitih koncentracija indol-buterne kiseline (IBA) i alfa-naftil sirćetne kiseline (NAA) na procenat ožiljavanja zrelih reznica u šest sorti smokve. Konstatovan je različit uticaj egzogene primjene fitohormona IBA (1000, 2000, 3000, 4000 ppm ) i NAA 0,5% na uspješnost ožiljavanja zrelih reznica smokve. Najniže prosječne vrijednosti ožiljavanja konstatovane su u reznica koje nisu tretirane fitohormonima (kontrola) kod svih ispitivanih sorti smokve, a zatim kod reznica koje su tretirane sa fitohormonom NAA 0,5%. Najbolje ožiljavanje zrelih reznica smokve zabilježeno je primjenom IBA u koncentraciji od 4000 ppm i iznosilo je za sve sorte iz ogleda (89,25%,) a najslabije ožiljavanje je registrovano kod reznica koje nisu tretirane fitohormonom (71,94%). Od ispitivanih sorti smokve, kod svih primjenjenih tretmana, jednorodna sorta „Rezavica“ se najbolje ožiljavala (85,14%), a najslabije dvorodna sorta „Petrovača crna“. Povećanje procenta ožiljavanja zrelih reznica je konstatovano kod svih ispitivanih sorti smokve, srazmjerno povećanju koncentracije rastvora IBA, Analizom varijanse i LSD testom konstatovane su statističke razlike između ispitivanih sorti smokve, gdje uspjeh ožiljavanja zavisi od egzogenog tretiranja reznica različiti vrstama i koncentracijama fitohormona. Upotreba većih koncentracija IBA (3000 i 4000 ppm) pokazala se najboljom i kao takva se može preporučiti u tehnologiji proizvodnje sadnica smokve na vlastitom korijenu.

This paper presents the results of applying different concentration of exogenous indole-butyric acid (IBA) and Alpha-naphthyl acetic acid (NAA) on rooting of mature cuttings in six varieties of figs. Ascertained the different effects of exogenous application of phytohormones IBA (1000, 2000, 3000, 4000 ppm) and NAA 0.5% on the success of rooting of mature cuttings of fig. The lowest average values were found in the rooting of cuttings which are not treated with phytohormones (control) for all tested varieties figs, and then with the cuttings treated with phytohormones NAA 0.5%. Rooting cuttings of ripe figs recorded by applying IBA at a concentration of 4000 ppm and accounted for all varieties from the trial (89.25%) and the lowest was registered in rooting cuttings that are not treated with phytohormones (71.94%). The cultivar figs, with all the applied treatment, homogeneous variety "Rezavica" the best ožiljavala (85.14%) and least two-fold varieties "Petrovaca Black". Increase the percentage of rooting of mature cuttings was noted in all tested varieties of figs, in proportion to the increase in the concentration of IBA solution, analysis of variance and LSD test were found statistical differences between the varieties of figs, where success depends on rooting cuttings of exogenous treating different types and concentrations of phytohormones. The use of higher concentrations of IBA (3000 and 4000 ppm) proved to be the best, and as such can be recommended in technology production plants figs on its own root.
