AB  - The study describes the effect of naphthenates and their fractions on rooting of in vitro grown Sequoia sempervirens (Lamb. ex D. Don) Endl. shoots. Natural naphthenic acids have been isolated by alkaline extraction from the middle gas fraction of the crude oil. Sequoia sempervirens shoots (1 cm in length) were grown on Murashige and Skoog (1962) (MS) medium supplemented with either total naphthenate preparation, naphthenate fractions obtained by extraction on different pH (pH 2, pH 4, pH 7 and pH 9), or indole-3-butyric acid (IBA) in different concentrations (twenty treatments tested). The rooting testing was based on number and total length of roots formed after four weeks of in vitro growth. Similarly to total length of roots, the highest number of roots per explant (approximate to 7) was achieved in medium containing 50 mu M of the naphthenate fraction extracted at pH 2 and in medium containing 50 mu M of the fraction extracted at pH 9. That is triple higher than in the control and significantly better than in the best IBA-treatment (50 mu M IBA), where five roots per explants in average were formed. Similar to the results obtained for some agricultural and tree forest species, our results with Sequoia sempervirens confirm the possibility of rooting stimulation by naphthenates.

AB  - Naphtenic acids, by-product in oil refinement, are well known soil pollutants and active substances in preparations for plant and wood protection. The results of multiannual research indicated the possibility of their utilization for stimulation of cutting rooting. Two to three cm high shoots of Populus alba cl. LBM genotype were set for one hour on ACM medium with 4, 16 or 48 μM concentration of indol-3-butyric acid, 1-naphthalene acetic acid or Na-salts of naphthenic acids (for which the effect of 10 and 30 minutes treatment on medium with 48 μM was also examined). Then, treated micro-shoots were transferred on ACM medium without hormones. The differences among treatments were the most distinguishable for rooting percentage after two weeks of cultivation. One-hour treatment on the medium with 16 μM and 30 minutes treatment on medium with 48 μM of Na-naphthenates gave the best results. .
AB  - Naftenske kiseline, nusproizvodi u procesu rafinacije nafte, su poznati zagađivači zemljišta i aktivna materija sredstava za zaštitu biljka i drveta. Rezultati višegodišnjih istraživanja ukazuju i na mogućnost njihove upotrebe kao sredstava za stimulaciju oživljavanja reznica. Dva do tri cm visoki mikroizbojci genotipa Populus alba cl. LBM su jedan čas bili postavljeni na ACM podlozi sa 4, 16 ili 48 μM koncentracijom indolbuterne kiseline, naftilsirćetne kiseline ili Na-soli naftenskih kiselina (kod kojih je ispitan i uticaj 10-to i 30-to minutnog tretmana pri koncentraciji 48 μM). Zatim su mikroizbojci postavljeni na ACM podlogu bez hormona. Razlike među tretmanima su se najviše ispoljile u procentu ožiljavanja nakon dve nedelje kultivacije. Jednočasovni tretmani na podlozi sa 16 μM i polučasovni na podlozi sa 48 μM Na-naftenata su dali najbolje rezultate. .

AB  - The paper describes a study of the effect of salts of natural naphthenic acids on the rooting of young sunflower cuttings and latteral branching of interspecies sunflower hybrids. Naphthenic acids were obtained by alkaline extraction from atmospheric gas oil fraction of Vojvodina crude oil "Velebit" and purified by column chromatography on alumina. Their sodium salts in concentrations of 1×10-7 mol/dm3 stimulated the formation of adventitious roots in sunflower cuttings even by a factor of 40 compared with control, the effect being also observed in lateral branches of interspecies sunflower hybrids. The obtained results suggest the possibility of using naphthenic acids as a means for rooting of plant cuttings.
