“…SE have been shown to increase plant growth (van Staden et al, 1994), chlorophyll levels (Blunden et al, 1997), flowering and yield (Crouch et al, 1990;Eris et al, 1995), and seed germination (Demir et al, 2006;Kumar and Sahoo, 2011). They increase the success of in vitro propagation (Vinoth et al, 2012) and enhance plant protection against pathogens and pests (Hankins and Hockey, 1990;Jayaraman et al, 2011;Khan et al, 2009;Klarzynski et al, 2003;Loureiro et al, 2012;Mercier et al, 2001).…”

Background: Calibrachoa x hybrida (Solanaceae) cultivars are widely used in North and South America as ornamental plants. Their potential as a source of antimicrobial compounds might be enhanced by seaweed extract (SWE) applications. Methods: SWE of Ascophyllum nodosum were applied at 5 and 7 ml/L as a soil drench or foliar spray on Calibrachoa cultivars of Superbells® 'Dreamsicle' (CHSD) and Superbells® 'Frost Fireʼ (CHSF). The total phenolics, tannins and antioxidants composition as well as specific flavonols in leaf extracts were determined. Further, the chemical composition of SWE was assessed. Results: The drench and foliar SWE treatments significantly enhanced Calibrachoa cultivars leaf number and area, dry weight, plant height, antioxidant capacity as well as phenolic, flavonols and tannin content. The increased growth and composition of phenols, flavonols and tannins was attributed to the stimulatory effects of SWE mineral composition. The antifungal activity of Calibrachoa cultivars was significantly enhanced following SWE treatments and the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) were in the range of 0.07-0.31 mg/ml and from 0.16 to 0.56 mg/ml, respectively. Moreover, antibacterial activity was significantly increased and the MIC and minimum bactericidal concentration (MBC) measurements were in the range of 0.06-0. 23 mg/ml and from 0.10 to 0.44 mg/ml, respectively. The most sensitive fungus to SWE treatments was C. albicans and the most sensitive bacterium was E. cloacae. Conclusion:The results suggest that enhanced antifungal and antibacterial activities might be attributed to significant increases of phenolic, flavonols and tannin contents, which ultimately enhance the potential of Calibrachoa as a natural source of alternative antibiotics.

“…One of them is Kelpak SL obtained from brown seaweed species Ecklonia maxima, which contains a proportionately greater amount of auxin relative to cytokinin (11.0 mg/l auxin and 0.031 mg/l cytokinin). This stimulates cells elongation and contributes to improved growth of plants and their root system (Basak, 2008;Basak and Mikos-Bielak, 2008;Beckett and van Staden, 1989;Matysiak and Kaczmarek, 2008;Russel, 2002;Stirk and van Staden, 1997;Szabo and Hrotko, 2009;Van Staden et al, 1994). Increase of the production of hormones in the plant, which is beneficial to improve the quality and amount of yield and improve plant health (Arthur, et al,2003;Beckett et al, 1994;Horoszkiewicz-Janka and Jajor, 2006;Matysiak and Adamczewski, 2006;Matysiak and Kaczmarek, 2008;Oyoo et al, 2010;Russel, 2002;Sas-Paszt et al 2008;Verkleij, 1992;Zodape, 2001).…”

Biostimulators applied in the cultivation of plants stimulate the processes of life and increase their hardiness to stress conditions, contributing to greater and better quality of yield. One of them is Kelpak SL obtained from brown seaweed species Ecklonia maxima. The aim of experiment carried out was to assess a potential effect of Kelpak SL on bean (Phaseolus vulgaris L.) cultivar Aura yield. The trial was carried out during 2010-2011 years on the experimental field of Institute of Agricultural Sciences The State School of Higher Education in Chełm. Treatments with Kelpak were carried out in 2 different concentrations (0.2 % and 0.4%) and in two application frequencies (one application in the 2-3 leaves stage or two applicationsfirst in the 2-3 leaves stage and second at the beginning of the bean's blooming). Received results were compared with the control where Kelpak was not applied. The number and the weight of seeds, the number of pods and the weight of thousand seeds per 1 m 2 were recorded. The beneficial effect of seaweed extract of Ecklonia maxima on the yield of beans (Phaseolus vulgaris L.) was demonstrated. The highest number and weight of seeds and number of pods were obtainment in the combination of once application with 0.2 % solution of Kelpak SL in 2010 and once application with 0.4 % solution of Kelpak SL in 2011. Application of Kelpak SL significantly increased number and weight of seeds and number of pods compared with the control where Kelpak SL was not applied.
