AB  - The study describes the rooting effect of naphthenates and their fractions on in vitro grown Robinia pseudoacacia L. shoots. Natural naphthenic acids have been isolated by alkaline extraction from middle fraction of crude oil type “Velebit” from Vojvodina, characterized and fractionated. Black locust shoot bases were immersed in ACM medium [Ahuja, 1984] without agar supplemented with either 10, 50 or 100 µM of basic naphthenate preparation, naphthenate fractions obtained by extraction at different pHs (pH 2, pH 4, pH 7 and pH 9), or indole3-butyric acid (IBA). Treated shoots have been then grown on hormone-free medium for four weeks. Significant differences among test treatments were recorded during the third and the fourth week of in vitro cultivation. Final evaluation was performed on the basis of rooting percentage after four weeks of cultivation. The highest rooting percentage (>70%) was achieved after the treatment with solution containing 50 µM of IBA. However, treatment with 10 µM of naphthenate preparation achieved also positive effect on rooting (>60%). Average rooting percentage in the control treatment was just 45%. Our results with black locust confirm previous results gained with some other agricultural and forest tree species that naphthenates have the potential to stimulate rooting in shoots and cuttings.

AB  - In order to investigate the effect of phytohormones exogenous auxins on the level of the mechanical injury induced oxidative stress, intensity of lipid peroxidation (LP) was measured in rootstocks of cherry softwood cuttings. Basal part of the cuttings and leaves of five rootstocks (Mahaleb 1 and 2, Gisela 5, European ground cherry (EGC) and “Oblačinska” sour cherry) were sampled 0, 2, 4 and 6 days after cutting. Cuttings were treated with 0.5% solutions of three auxins: α-naphthylacetic acid (NAA), indolebutyric acid (IBA) and combination of these two (INCIT K). Results obtained for the LP intensity varied depending on the rootstock, plant organ and auxin applied. The best LP-lowering effect of auxins occurred in all genotypes when treated with NAA. In the leaves, the LP peaked on the 2nd day, while the best LP-lowering effect was recorded in European ground cherry rootstocks on the 4th day, independently of auxin applied. The highest MDA production in leaves was recorded in Mahaleb 2 and European ground cherry rootstocks treated with IBA (60-90% higher than control) two days after the cuttings were made. It has been established that in the most of the rootstocks examined auxins showed lowering effect on LP which points to their positive effect, not only on rooting of softwood cuttings, but on their antioxidant protection system, as well.
AB  - U radu je ispitan nivo oksidativnog stresa izazvanog mehaničkom povredom biljke prilikom proizvodnje reznica, u bazalnom delu i listovima pet podloga za višnju i trešnju (Magriva 1 i 2, Gizela 5, Stepska (EGC) i “Oblačinska” višnja). Istovremeno, reznice su tretirane 0.5% rastvorima tri auksina (α-naftilsirćetna kiselina, NAA, indol- buterna kiselina, IBA i kombinacija ovih hormona, INCIT K), u periodu od 60 min, kako bi se utvrdio efekat auksina na antioksidantni status reznica višnje. Uzorci su uzimani nakon 0, 2, 4 i 6 dana. Kontrolu su činile reznice držane u vodi bez hormona. Intenzitet lipidne peroksidacije (LP) je meren kao produkcija malondialdehida (MDA), spektrofotometrijski na 532 nm, i izražen je u nmol MDA g-1 sveže mase.
Dobijeni rezultati su varirali u zavisnosti od podloge, organa biljke i primenjenih auksina. Utvrđeno je da je intenzitet LP u bazalnom delu bio najveći prvog dana, na- kon ozleđivanja, a da su svi ispitivani auksini snižavali produkciju MDA u narednim danima. Najbolji efekat pokazala je Magriva 1 tretirana sa NAA. U listovima, LP je bila najveća 2. dana, a najbolji efekat na smanjenje pokazali su primenjeni auksini u Stepskoj višnji (4. dana). Najveća produkcija MDA u listovima zabeležena je u Magrivoj 2 i Stepskoj višnji tretiranih sa IBA, 2. dana nakon odsecanja reznica (60-90% više od kontrole). Utvrđeno je da u većini podloga pod dejstvom ispitivanih hormona dolazi do smanjenja intenziteta LP što ukazuje na pozitivan efekat primenjenih auksina, ne samo na ožiljavanje reznica nego i na njihov antioksidantni sistem.

AB  - The oxidative stress and antioxidant systems in soybean leaves and roots infected with plant pathogen Aspergillus niger were studied following treatment with different concentrations of cholic acid. Several oxidative stress parameters were analyzed: production of superoxide (O-2 (center dot-)) and hydroxyl radicals ((OH)-O-center dot), lipid peroxidation (LP), and superoxide dismutase (SOD; EC 1.15.1.1) activity, as well as the content of reduced glutathione (GSH). Results showed that inoculation with A. niger led to the increase of O-2 (center dot-) production and GSH quantities in leaves and (OH)-O-center dot in roots. The highest activity of SOD occured in infected plants treated with cholic acid in concentrations of 40 and 60 mg L-1 which ultimately led to a decrease in O-2 (center dot-) production. Inoculation with Aspergillus in combination with elevated cholic acid concentrations also increased (OH)-O-center dot production which is correlated with increased LP. These results may support the idea of using cholic acid as an elicitor to trigger hypersensitive response in plant cells. Use of cholic acid may also actively contribute to soybean plants defense response against pathogen attack.

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.

AB  - Five populations of each H. molis, H. maximiliani, H. rigidus and H. tuberosus were screened for resistance to stem form of Sclerotinia. On the basis of the results obtained by screening, nine crosses of resistant populations with either other wild species populations or with cultivated sunflower were made. As in some crosses a small quantity of seed was produced and the seeds germinated poorly, modified tissue culture methods were used to enhance germination and produce clones of interesting plants. These methods were found to be efficient both for seed germination and plant production and multiplication.
AB  - Testirano je po pet populacija H. molis, H. maximiliani, H. rigidus i H. tuberosus na otpornost prema Sclerotinia stabla. Na osnovu dobijenih rezultata izvršeno je devet ukrštanja otpornih populacija sa drugim divljim vrstama ili gajenim suncokretom. Kako je u nekim slučajevima dobijena mala količina semena koja su slabo klijala, korišćene su modifikovane metode kulture tkiva da bi se povećala klijavost i proizveli klonovi interesantnih biljaka. Ove metode su se pokazale efikasnima i za naklijavanje semena i za proizvodnju i umnožavanje biljaka.
