The effect of substrata on rooting of the vegetative apple rootstocks

Abstract

The paper presents the results of evaluation of the effects of substrata on rooting of the following vegetative apple rootstocks: M9, Emla, Pajam 1 and Pajam 2. Glistenjak, Floradur 1, Floradur 2, Sondermischung grdernererde and Kekkila. Substrata were applied in quantity of 1.5 kg per mother bush, with soil covering as the control. The following parameters were monitored in the study: number of sprouts per bush, sprout length and diameter, length of the rooted section, root weight, number and length of all roots and number and length both of ramified and unramified roots. The substrata had positive effect on all evaluated parameters, which further implies that these should be applied in more intensive rootstock production with the aim of obtaining high quality planting material intended for the establishment of intensive plantings.

Na osnovu dvogodišnjih ispitivanja uticaja različitih supstrata na ožiljavanje vegetativnih podloga jabuke utvrđene su značajne razlike kod ispitivanih parametara kod sve tri podloge za jabuku: M 9 Emla, Pajam 1 i Pajam 2. U poređenju sa kontrolnom varijantom korišćeni supstrati, glistenjak, Floradur 1, Floradur 2, Sondermischung grdngrerde i Kekkila su ispoljili pozitivni uticaj na ožiljavanje mladica, broj žila, dužinu žila i masu žila.
