Enhancement of Antioxidant Properties of Lavender (Lavandula officinalis L.), Sage (Salvia officinalis L.) and Basil (Ocimum basilicum L.) by Application of Natural Biostimulants

The aim of this study was to examine the effects of seaweed extract (Algaren), nettle extract and microbial biostimulant (Slavol) on total phenolics and flavonoids and antioxidant capacity of leaves of lavender (Lavandula officinalis L.), sage (Salvia officinalis L.) and basil (Ocimum basilicum L.). The study was carried out in a greenhouse located in Vitez, Bosnia and Herzegovina. The experimental trial was set up in a randomized block design with four biostimulant treatments in three replications. The first application of biostimulant was carried out immediately after the transplanting of seedlings, and the second and third treatments 15 and 30 days later, respectively. Total phenolic and flavonoid contents and ferric-reducing/ antioxidant power (FRAP) assay were used to evaluate the antioxidant properties of each leaf extract. The nettle extract was found to be the most effective in increasing total phenolics, flavonoids, and antioxidant capacity in leaves of studied plants. In this study, the antioxidant capacity of leaf extracts was in line with total phenolics/flavonoids, regardless of plant species and biostimulant treatments, suggesting that phenolic compounds greatly contribute to antioxidant capacity of studied plants

Uticaj različitih stimulatora na parametre razvoja kadifice (Tagetes patula L.)

Kadifica (Tagetes patula L.) se ubraja u grupu jednogodišnjih cvjetnih kultura, a zbog svojih dekorativnih osobina posljednjih godina zauzima sve veći udio u proizvodnom asortimanu proizvođača cvijeća u Bosni i Hercegovini.Sve veća potražnja za rasadom kadifice nameće potrebu intenziviranja njene proizvodnje i podizanje njene kvalitete, a jedan od načina kojim se to pokušava postići je primjena različitih stimulatora rasta. Cilj ovog rada je bio ispitati uticaj stimulatora rasta Bio-algeena S-92, Slavola i Ergonfilla na parametre rasta i razvoja kadifice (Tagetes patulaL.). Od parametara rasta i razvoja kadifice u ovom istraživanju ispitivani su: sadržaj pigmenta u listovima i površina listova, te prečnik cvijeta i broj cvjetnih glavica po biljci. Rezultati istraživanja su pokazali da ni jedan od primijenjenih stimulatora rasta nije iskazao statistički značajan uticaj na povećanje estetski važnih parametara kvaliteta cvijeća: prečnika cvijeta i broja cvjetnih glavica na biljci iz čega se može zaključiti da kadifica nije zahtjevna kultura za uzgoj jer je u stanju uspješno razviti svoje cvjetove čak i ako joj se u toku uzgoja ne dodaju stimulatori rasta. Preduslov za ostvarenje navedenog je da supstrat u kojem se kadifice uzgajaju svojim fizičkim i hemijskim karakteristikama zadovoljava sve kriterije potrebne biljkama za njihov uspješan rast i razvoj

Effects of different growth stimulators on development parameters of marigold (Tagetes patula L.)

Marigolds (Tagetes patula L.) are hardy annuals, and because for their decorative qualities, occupies an increasing share of the production line of flower producers in Bosnia and Herzegovina. The growing demand for marigold seedlings imposes the need to intensify their production and improving their quality, and one of the way to do that is application of different growth stimulators.The aim of this study was to examine the impact of growth stimulators Bio-Algae S-92, SLAVOL and Ergonfilla on marigolds (Tagetes patula L.) growth parameters. The following parameters were examined: the content of pigment in leaves and leaf area and diameter of the flowerand the number of flower heads per plant. The results showed that none of the applied growth stimulators demonstrated a statistically significant effect on increasing aesthetic quality of the important parameters of flowers: flower diameter and the number of flower heads per plant. It can be concluded that marigolds are not demanding plants, because there are able to bloom without growth stimulants application. The most important thing is to have soil which satisfies physical and chemical characteristics for successful growth and development of marigold
