Journal Title: Лісівництво і агролісомеліорація - Year 2016, Vol 129, Issue
Abstract
The article reports the results of study of using amino acid humate fertilizer “Rokohumin” for cuttings propagation of decorative coniferous of Western arborvitae (f. Smaragd) (Thuja occidentalis Golden Smaragd), Canadian spruce (f. columnar) (Picea glauca Conica Maigold), common juniper (f. columnar), (Juniperus communis L.), horizontal juniper (Juniperus horizontalis Moench.), Chinese juniper (Juniperus chinensis 'Stricta') and rock juniper (Juniperus scopulorum Sarg.) in decorative nursery of State Enterprise “Trostyanetske Fores Tconomy”. It was found that the use of “Rokohumin” by leaf feeding method helps overall improve of condition index, reduces the percentage of dry cuttings and increases the percentage of healthy cuttings in variants within the experiment. The proportion of rooted cuttings increases by 3–16 %. For first year cuttings, by controls an ascending series was identified according to rooting ability: horizontal juniper – 33.3 %; common juniper (f. columnar) – 57.9 %; Chinese juniper – 60.8 %; Western arborvitae (f. Smaragd) – 70.0 % and rock juniper – 85.7 %.
