Light emitting diodes (LEDs) are potential light sources for in vitro plant cultures. Here, axillary blackberry shoots were grown MS medium with indole-3-butyric acid (1 mg L−1), naphthalene acetic (0.5 and sucrose supplementation (0–60 g L−1) the cultures incubated under four treatments: three LED treatments (blue + red (2:1 spectral ratio), blue (1:2), cool warm white (1:1)) a standard flores...

Foodborne illness outbreaks have significantly impacted public health. The contact antibacterial nanomaterials may potential migration of and thus bring safety concerns. In this work, we develop photo-triggered nano-generators for on-demand release essential oil vapor to achieve a non-contact strategy between target bacteria. This nano-generator (Fe3O4@[email protected]/carvacrol, FPZC) is comp...

Duckweed (Lemna minor L.) is a model plant suitable for investigation into plant physiology, biochemistry and ecotoxicology. Depending on the type of the experiment, duckweed is cultivated on different nutrient media under various chamber conditions. In our work, duckweed was cultivated on Pirson-Seidel’s nutrient solution supplemented with 5, 7.5 or 10 g L–1 sucrose under cool white (CW) or Gr...

The effects of major mineral salts, L-glutamine, myo-inositol and carbon source on shoot bud proliferation of date palm (Phoenix dactylifera L.) cv. Mejhoul were evaluated. Different concentrations of ammonium nitrate (NH4NO3; 550, 825 or 1650 mg/L), potassium nitrate (KNO3; 633.3, 950 or 1900 mg/L), calcium chloride dehydrate (CaCl2·2H2O; 147, 220 or 440 mg/L), potassium dihydrogen phosphate (...

The incretin hormones, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), play an important role in glucose homeostasis in both health and diabetes. In mice, sucralose, an artificial sweetener, stimulates GLP-1 release via sweet taste receptors on enteroendocrine cells. We studied blood glucose, plasma levels of insulin, GLP-1, and GIP, and gastric emptying ...

BACKGROUND Essential oil components eugenol and carvacrol (ranging between 100 and 200 ppm for carvacrol and between 250 and 750 ppm for eugenol) were tested for antifungal activity against foodborne pathogenic fungal species Aspergillus carbonarius A1102 and Penicillium roqueforti PTFKK29 in in vitro and in situ conditions. MATERIALS AND METHODS In vitro antifungal activity of eugenol and ca...

We studied the influence of sucrose and nitrogen concentration on in vitro flowering and fruit setting in elongated shoots of Withania somnifera. BA (1.5 mg/l) and IAA (0.3 mg/l) on MS medium supplemented with 4% sucrose showed 67% of in vitro flower induction frequency, 9 flowers/shoot, 4 fruits/shoot and 11 seeds/fruit in elongated-shoots. Different concentrations of nitrogen sources (L-gluta...

The dormancy characteristics and optimum conditions for seed germination of Alstroemeria ligtu had not been explained. In vitro and in vivo alstroemeria (A. ligtu hybrid) seed germination tests were conducted in a Randomized Completely Design at two different treatments (gibberellic acid (GA3) 0, 100, 200 and 400 mg/l with and without stratification in 5±1oC) in four replications. Seeds were pl...

Rosa persica with a distinctive red eye is a good candidate for addition to the breeding pool of roses. In order to optimize micropropagation of R. persica, three culture media (MS, QL and VS) were compared. The maximum growth rate was observed in the VS medium. Addition of FeEDTA (Fe: 65.4 mg/l), calcium gluconate (Cg: 2.7 g/l) and Gamborg vitamins (B5) instead of VS vitamins, alone or in comb...
