Abstract:
Violation of homeostasis is often connected with a deficiency or excess of certain elements. Undeniable value of biologically active substances of plants is that they are contained in plant raw material in natural balanced complexes and they are an important source of macro- and microelements for a human organism. Study of a chemical composition, including macro- and microelements, a pharmacological effect of Verbena species is a basis for conduction of further researches. There are 250 species of Verbena genus, 3 of which, namely Verbena officinalis L., Verbena supina L. and Verbena hybrida Hort are growing in Ukraine. The aim of our research was to study macro- and microelements in the raw material of Verbena genus species, to reveal the influence of the conditions of growing on the content of elements in the Verbena officinalis L. herb, to compare element composition of the Verbena officinalis L. herb and herbal extracts. Macro- and microelement composition of raw material was researched by using the method of atom-emission spectrometry with inductively bounded plasma iCAP 7000 Duo. To determine the influence of the conditions of increase of macro- and microelements in Verbena officinalis L. herb, their quantity in soils and plants from different areas of growing was defined. To reveal the intensity of absorption of macro- and microelements from the soil by the plants, the coefficients of their biological accumulation were calculated. The comparative determination of the element composition of Verbena officinalis L. herb and herbal extracts VOH-0 (extractant – purified water) and VOH-7 (extractant – 70% ethanol) was also carried out to determine the degree of elements transfer from plant raw material into extracts. Results of the research show that in the samples of Verbena officinalis L. herb, Verbena hybrida Hort. herb and Verbena supine L. leaves there are 22 inorganic elements. Results of studying of element composition of Verbena officinalis L. herb and samples of soil from different areas of growing in Ivano-Frankivsk and Ternopil regions show that the quantitative and qualitative compositions of microelements depend on element exchange of these plants, conditions of growing and element composition of soil. The reverse dependence between the content of most elements in the soil and the coefficient of their accumulation in plants was found out. Concentration of elements in the herb and extracts was identified to have the same profile, but the quantitative content of elements was different, which was influenced by the extractor (purified water, 70% ethanol). Results of our research are currently relevant; they should be taken into account in the development of new herbal medicines, which would have desirable pharmacological effect in the future.

Abstract:
Abstract Verbena officinalis (common vervain) is a medicinal plant species widely distributed in the world and commonly used in folk medicine of different countries, including traditional Chinese medicine. Monographs on “Verbenae herba” have been included in the European Pharmacopoeia since 2008, and in the Chinese Pharmacopoeia since 1995. This work presents botanical characteristics of this species. It reviews the current knowledge of its chemical composition, which is a rich source mostly of iridoids, phenylpropanoid glycosides, phenolic acids, flavonoids, terpenoids, and essential oil. A large part of this article summarizes traditional medicinal uses and professional pharmacological in vitro and in vivo studies that prove new important applications, e.g., antioxidant, antimicrobial, anti-inflammatory, neuroprotective anticancer, analgesic, or anticonvulsant of verbena herb extracts and individual metabolites. Moreover, emphasis is put on the use of V. officinalis in the food and cosmetics industries, especially due to its antioxidant, antibacterial, and anti-inflammatory properties, and the presence of essential oil with an attractive fragrance composition. This paper also presents the state of biotechnological studies of this species.

Abstract:
The nutritional profiles of common and lemon verbena leaves were analyzed (proximate constituents, free sugars, organic acids, tocopherols, and fatty acids) and the leaves were prepared in hydromethanolic and aqueous (decoctions and infusions) extracts. The phenolic compound composition and antioxidant activity (2,2-Diphenyl-1-picrylhydrazyl (DPPH); 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), ferric-reducing antioxidant power (FRAP); and cupric-reducing antioxidant capacity (CUPRAC) assays) of the extracts were characterized. The nutritional composition varied between the studied species, with lemon verbena showing higher amounts of protein, ash, and fat than common verbena, whereas the opposite trend was recorded for the dietary fiber content. The main free sugars detected in both species were fructose, glucose, and sucrose, which were present in higher amounts in the common verbena samples. Succinic acid was the most abundant organic acid in both species while high amounts of oxalic acid were detected in lemon verbena. The main fatty acids in both species were α-linolenic, palmitic, and linoleic acid. Regarding the phenolic compound content, the extracts of lemon verbena presented higher amounts of total phenolic compounds (TPCs), total flavonoids (TFs) and total phenolic acids (TPAs) than the common verbena extracts while the aqueous extracts (infusions and decoctions) were richer in TPCs, TFs, and TPAs than the hydromethanolic ones in both species. Nine phenolic compounds were identified and quantified, including seven phenolic acids and two flavonoids. The lemon verbena samples were characterized by higher antioxidant activity compared to the common verbena samples while the aqueous extracts showed higher antioxidant efficacy than the hydromethanolic ones. In conclusion, both species showed promising results in terms of the nutritional value, chemical composition, and antioxidant activities, which were positively correlated with the phenolic compound contents. Moreover, the extraction protocol may affect the chemical composition and bioactive properties of both species, with aqueous extracts showing better results than hydromethanolic ones.

Abstract:
Abstract Poultry litter ash (PLA) is a byproduct of bioenergy production and an effective P source for horticultural crops since it reduces P losses from container production due to its low P solubility. Experiments were conducted to determine effects of rate and placement of PLA on P loss from greenhouse crop production and growth and quality of two commonly-grown greenhouse crops, Verbena canadensis Britton ‘Homestead Purple' and Lantana camara L. ‘New Gold', by comparing two rates (140 and 280 g·m−3 P or 0.4 and 0.8 lb·yd−3) and two application methods (post-plant topdressed and pre-plant incorporated). Leachate-dissolved reactive phosphorus (DRP) concentrations were reduced by an average of 24% as P rate was reduced from 280 to 140 g·m−3, but were 134% less on average when PLA was topdressed instead of incorporated. Foliar P concentrations were less 33% and 44% for verbena and lantana, respectively when plants were topdressed compared to incorporated. Shoot biomass of verbena and lantana was 9% and 24% greater, respectively, when incorporating instead of topdressing PLA. As a P source, PLA should be pre-plant incorporated within the substrate at a total P rate between 140 g·m−3 (0.4 lb·yd−3) and 280 g·m−3 (0.8 lb·yd−3). Index words: phosphorus, poultry litter ash, Verbena canadensis Britton ‘Homestead Purple', Lantana camara L. ‘New Gold', dissolved reactive phosphorus. Species used in this study: ‘Homestead Purple' verbena (Verbena canadensis Britton); ‘New Gold' lantana (Lantana camara L.).

Abstract:
Lemon verbena (Aloysia triphylla) infusion, a widely consumed herbal tea, contains significant amounts of polyphenols such as flavone diglucuronides and phenylpropanoid glycosides (mainly verbascoside). We have recently shown that lemon verbena infusion offers beneficial effects against dextran sodium sulphate (DSS)-induced colonic inflammation in rats. The present study aimed to evaluate the bioavailability and intestinal absorption of polyphenols derived from lemon verbena infusion in both healthy and colitic rats. For this purpose, lemon verbena infusion was given to rats ad libitum for 14 d, and then 4 % DSS was added to the infusion for 7 d. Before and after DSS administration, 24 h urinary excretion of polyphenols was determined. Flavones were excreted in the urine as conjugated aglycones, and their excretion was not significantly altered by colonic inflammation. Only trace amounts of verbascoside were excreted in the urine, but various metabolites (hydroxycinnamic acids) were detected. The urinary excretion of hydroxycinnamic acids, particularly that of caffeic acid, increased after DSS administration (P< 0·05). Only flavone aglycones (luteolin and diosmetin) were excreted in the faeces in small proportions (3·2 % of ingested flavones). Intestinal absorption of lemon verbena polyphenols was examined using an in situ intestinal perfusion model. Intestinal absorption of verbascoside and flavone diglucuronides did not significantly differ between the healthy and colitic rats. Collectively, these results show that intestinal absorption and urinary excretion of lemon verbena flavone diglucuronides were not altered by colonic inflammation, but that urinary excretion of hydroxycinnamic acids derived from verbascoside was affected in a colitic situation.

Abstract:
Shoot stretching in plug production reduces quality and makes mechanized transplanting difficult. The objectives of this study were to measure seedling emergence and shoot height of plugs as affected by paclobutrazol application during seed soaking, priming, or coating on seedling emergence and height. Verbena (Verbena ×hybrida Voss. `Quartz White'), pansy (Viola wittrockiana L. `Bingo Yellow Blotch'), and celosia (Celosia cristata L. `New Look') seeds were soaked in water solutions of paclobutrazol and subsequently dried on filter paper at 20 °C for 24 h. Soaking seeds in paclobutrazol solutions before sowing reduced growth and percentage seedling emergence of verbena and pansy but had little effect on those of celosia. Verbena seeds soaked in 50, 200, or 500 mg paclobutrazol/L for 5, 45, or 180 min produced fewer and shorter seedlings than controls. Osmopriming verbena seeds with 10 to 500 mg paclobutrazol/L reduced seedling emergence. Seedling height and emergence percentage of pansy decreased with increasing paclobutrazol concentrations from 2 to 30 mg·L–1 and with soaking time from 1 to 5 min. The elongation of celosia seedlings was reduced by soaking seeds in 10, 50, 200, or 500 mg paclobutrazol/L solutions for 5, 180, or 360 min. However, these reductions were negligible and without any practical application.

Abstract:
Verbena × hybrida is an ornamental annual used in rock gardens as an edging plant and hanging baskets. It comes in a variety of colors and grows approximately 1.5 to 2.5 cm (6 to 10 inches) high. In the spring of 2002, verbena cv. Lavender Shades plants from California showing leaf mosaic symptoms tested positive for potyvirus using an antigen-coated plate enzyme-linked immunosorbent assay with our genus Potyvirus broad spectrum reacting PTY-1 monoclonal as the detecting antibody (3). The virus was transmitted mechanically to Nicotiana benthamiana by sap inoculation from infected verbena plants. Infected tobacco showed systemic mild mosaic symptoms. Total RNA extractions from infected verbena and tobacco leaves were used in reverse transcription-polymerase chain reaction (RT-PCR) assays with generic potyvirus-specific primers that amplify highly conserved 700-bp or 1,600-bp fragments from the 3′ terminus of most potyviruses. This region includes the 3′ noncoding region (3′NCR) and the potyviral coat protein (CP). The PCR-amplified fragments were cloned by using standard TA cloning procedures and sequenced using dye-terminator chemistry. The cloned nucleotide and putative coat protein amino acid sequences from the infected verbena and tobacco plants were compared with the corresponding regions of other potyviruses. Amino acid comparison of the CP region of the verbena po-tyvirus showed 95 to 96% identity to four pea mosaic strains (PMV) of Bean yellow mosaic virus (BYMV), 85 to 89% identity to 20 other strains of BYMV, 74 to 76% identity with six strains of Clover yellow vein virus (CYVV), and only 50 to 64% identity with 28 other potyviruses. Pairwise comparisons among and between the CP sequences of PMV, BYMV, CYVV, and other potyviruses revealed identities of 92 to 99% for BYMV∷ BYMV, PMV∷PMV, and CYVV∷CYVV; 84 to 89% for BYMV∷ PMV, 69 to 78% for BYMV∷CYVV and PMV∷CYVV, and 50 to 64% for all other potyvirus combinations. Additionally, similar pairwise analysis of the 3′NCR of the verbena potyvirus revealed 98 to 99% identity to PMV strains, 81 to 94% to other BYMVs, 68 to 75% to CYVVs, and 52 to 64% with other potyviruses. Other 3′NCR pairwise comparisons generally revealed the same identity trend as described for the CP. Further serological analysis with our panel of BYMV-specific, BYMV-subgroup, and potyvirus cross-reactive monoclonal antibodies (3) confirmed the designation of the verbena potyvirus isolate as a pea mosaic strain of BYMV. To our knowledge this is the first confirmed report of BYMV-pea mosaic strain in Verbena (1,2). References: (1) Agdia, Inc. Positive Ornamental Plant Samples. Agdia On-line Publication, 2003. (2) A.

Salt tolerance of seven Texas Superstar® perennials [Malvaviscus arboreus var. drummondii (Turk’s cap), Phlox paniculata ‘John Fanick’ (‘John Fanick’ phlox), Phlox paniculata ‘Texas Pink’ (‘Texas Pink’ phlox), Ruellia brittoniana ‘Katie Blue’ (‘Katie Blue’ ruellia), Salvia farinacea ‘Henry Duelberg’ (‘Henry Duelberg’ salvia), Salvia leucantha (mexican bush sage), and Verbena ×hybrida ‘Blue Princess’ (‘Blue Princess’ verbena)] was evaluated in a greenhouse experiment. Plants were irrigated with a nutrient solution at electrical conductivity (EC) of 1.1 dS·m−1 (control) or a salt solution at EC of 5.0 or 10.0 dS·m−1 (EC 5 or EC 10) for 8 weeks. ‘John Fanick’ and ‘Texas Pink’ phlox plants in EC 5 had severe salt foliage damage, while those in EC 10 were died. Mexican bush sage in EC 10 had severe salt foliage damage. Turk’s cap, ‘Katie Blue’ ruellia, ‘Henry Duelberg’ salvia, and ‘Blue Princess’ verbena had minor foliar damage regardless of treatment. EC 5 reduced the shoot dry weight (DW) by 45% in ‘Texas Pink’ phlox and 11% to 18% in ‘Katie Blue’ ruellia, ‘Henry Duelberg’ salvia, and mexican bush sage, but did not impact the shoot DW of Turk’s cap and ‘John Fanick’ phlox. EC 10 further decreased the shoot DW of ‘Katie Blue’ ruellia, ‘Henry Duelberg’ salvia, and mexican bush sage plants by 32%, 29%, and 56%, respectively. EC 5 decreased leaf net photosynthesis (Pn) of ‘Texas Pink’ phlox and mexican bush sage, while EC 10 reduced Pn of all species except ‘Henry Duelberg’ salvia and ‘Blue Princess’ verbena. ‘Katie Blue’ ruellia and ‘Blue Princess’ verbena had relatively lower leaf Na concentration and ‘John Fanick’ phlox, ‘Texas Pink’phlox, and mexican bush sage had higher leaf Cl concentrations. In summary, Turk’s cap, ‘Katie Blue’ ruellia, ‘Henry Duelberg’ salvia, and ‘Blue Princess’ verbena were the most tolerant perennials, and ‘John Fanick’ phlox, ‘Texas Pink’ phlox, and mexican bush sage were the least tolerant to salinity.

Abstract:
Verbena ‘Taylortown Red’ plants showed virus-like mottling symptoms. Virus purifications disclosed the presence of elongated and spherical particles, evidence of mixed virus infections, whereas double-stranded RNA analysis revealed the presence of several bands absent in healthy plants. After shotgun cloning, three viruses were identified in ‘Taylortown Red’: Broad bean wilt virus-1, Coleus vein necrosis virus, and a previously undescribed potyvirus. Given the importance of verbena to the ornamental industry, we studied the viruses found in ‘Taylortown Red’ and, in this article, we present our findings on the new potyvirus, provisionally named Verbena virus Y (VVY). VVY belongs to the Potato virus Y subgroup in the genus Potyvirus, has solanaceous plants, including potato, as alternative hosts, and can be transmitted by a ubiquitous pest in the ornamental industry, the green peach aphid.

Abstract:
Abstract Salvia leucantha (Mexican sage) and Verbena canadensis ‘Homestead Purple’ were treated with the plant growth retardants (PGRs), Cutless, Sumagic, B-Nine/Cycocel tank mixes, or Pistill under both greenhouse and nursery conditions. Increasing rates of all PGRs applied to both species reduced plant size in the greenhouse for 6 weeks after treatment (WAT). Growth reduction of Mexican sage with the most effective rate (providing greatest growth control) of each PGR over this period averaged 11% with Cutless, 15% with Sumagic, 23% with B-Nine/Cycocel tank mixes, and 25% with Pistill. For verbena, size control with the most effective rate of each PGR averaged 15% with Cutless, 18% with Sumagic, 27% with B-Nine/Cycocel tank mixes, and 29% with Pistill. After transplanting greenhouse-grown plants into outdoor ground beds, only Mexican sage treated with B-Nine/Cycocel were significantly smaller 4 weeks after planting (WAP). Greenhouse-grown verbena treated with Sumagic, B-Nine/Cycocel tank mixes, and Pistill and planted in the landscape were 15—23%, 18–25%, and 0–20% smaller, respectively, than control plants at 2 WAP, but by 4 WAP, all PGR-treated verbena were similar in size to control plants. Under nursery conditions, Cutless and B-Nine/Cycocel tank mix reduced Mexican sage size up to 4 WAT. None of the PGRs affected plant size at 6 WAT. The most effective rate of each PGR (averaged over the duration that a PGR was significant) suppressed shoot growth 16% for Cutless, 12% with Sumagic, 20% for B-Nine/Cycocel tank mixes, and 29% for Pistill. For verbena only, Sumagic suppressed growth up to 10% at 2 WAT, and no PGR effectively controlled growth under nursery conditions 4 WAT.

Abstract:
Web blight was observed on verbena (Verbena × hybrida) during July 1999 in a cultivar trial planting at Burden Research Plantation in Baton Rouge, LA. Foliage blight, stem lesions, and branch death were common symptoms on 12 of 24 cultivars in the trial. Plant death occurred in cvs. Babylon Florena (one of four plants), Purple Princess (two of four plants), and Taylortown Red (two of four plants). Isolations from infected leaves and stems on acidified water agar consistently yielded a fungus with the mycelial and cultural characteristics of Rhizoctonia solani. Pathogenicity tests were carried out by placing 5-day-old fungal mycelial plugs, grown on acidified potato dextrose agar, at the base of healthy verbena stems and holding plants in a dew chamber at 26°C. After 3 days, foliage blight and stem lesions appeared on inoculated plants, and plants were moved to a greenhouse where temperatures ranged from 23 to 32°C. Seven of nine inoculated plants died after 7 days; noninoculated plants remained healthy. The fungal pathogen was reisolated from all inoculated plants. The fungus was identified as R. solani anastomosis group (AG)-1 IB based on multinucleate condition, type of sclerotia produced, and ability to anastomose with R. solani tester isolates of AG-1 IB. This is the first report of web blight on verbena.

Abstract:
Rooting and growth of Verbena cuttings (Verbena × hybrids Voss) were measured to determine response to foliar-applied benzylaminopurine (BA). There was no rooting response to BA application when visible nodal roots were present at the base of the cutting. There was no response to 30, 100, or 300 mg BA/liter applied to the foliage 48 or 96 hours after excision from the stock plant. Rooting-zone dry mass, total cutting dry mass, and number of roots were increased by 30 mg BA/liter applied immediately after excision when there were no visible nodal roots at the base of the cuttings. Foliar application of BA at 10 or 30 mg·liter-1 increased lateral bud elongation of subsequently rooted shoots by 20% and 49%, respectively. Application of BA during cutting propagation to enhance subsequent lateral bud elongation does not appear to inhibit rooting in Verbena stem cuttings. Chemical name used: 6-benzylaminopurine (BA).

Abstract:
Over the last few years, people have been concerned about the narrow relationship between nutrition and health leading to an increasing demand of nutraceutical products and functional food. Lemon verbena (Lippia citriodora Kunth) has been traditionally used for respiratory, digestive, and muscular diseases, showing effects that are promoted by the antioxidant activity of its phytoconstituents. The antioxidant power of several lemon verbena extracts has been tested but its isolated compounds activity has not been described. The aim of the present work was to isolate phytochemicals from a commercial lemon verbena extract through a semi-preparative high-performance liquid chromatography approach for further evaluation of its individual antioxidant activity using three different methods. The structure-antioxidant activity relationships revealed the influence of substitutions in the strong antioxidant power exerted by glycosylated phenylpropanoids, in contrast to the low antioxidant capacity showed by iridoids. Development of enriched extracts in these compounds could lead to greater antioxidant effects and improved functional ingredients to prevent chronic diseases.

Abstract:
Purpose: To investigate the anti-hyperlipidemic effect of Caralluma edulis and Verbena officinalis.Methods: Phytochemical analysis of crude extracts of Caralluma edulis (Ce.Cr) and Verbena officinalis (Vo.Cr) were carried out. Hyperlipidemia was induced in mice with high-fat diet (HFD, 1.25 % w/w cholesterol, 0.5 % w/w cholic acid and 10 % v/w coconut oil). All the groups, except the saline-treated group, were fed on HFD for 4 weeks (lead-in period) to induce hyperlipidemia. Thereafter, the groups were treated with varying doses of the plant extract for 2 weeks (treatment period) as well as atorvastatin (10 mg/kg) reference standard. Body weight was measured fortnightly for all groups. Total cholesterol (TC), triglyceride (TGs) and low density lipoprotein (LDL) were assayed using Merck diagnostic kits. For histopathological analysis, liver slices were fixed in 10 % formalin and embedded in paraffin wax and was examined with the aid of hematoxylin and eosin staining (H & E).Results: Caralluma edulis (Ce.Cr) contains saponins, alkaloids, tannins, phenol, glycosides, terpenoids and flavonoids while Verbena officinalis (Vo.Cr) tested positive for the presence of alkaloids, carbohydrates, flavonoids, saponins and tannins. HFD increased total cholesterol (TC), triglyceride (TGs), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) compared to regulator diet (p < 0.001). Treatment of the animals with Ce.Cr and Vo.Cr dose-dependently (500 - 1000 mg/kg) reduced serum TC, TGs, LDL and VLDL (p < 0.05, p < 0.01, p < 0.001, vs. HFD group) and raised high density lipoprotein (HDL) (p < 0.01, vs. HFD group), similar to that observed with atorvastatin (10 mg/kg). The anti-hyperlipidemic effects of Ce.Cr and Vo.Cr were also confirmed via liver histopathology results, showing improved structure with no hepatocellular necrosis and fat accumulation.Conclusion: These results indicate that Caralluma edulis and Verbena officinalis exhibit antihyperlipidemic effect; thus, the plants have therapeutic potentials for the management of lipid disorders.Keywords: Caralluma edulis, Verbena officinalis, Anti-hyperlipidemia, Hepatocellular necrosis

Abstract:
Lemon verbena infusions are widely appreciated due to their agreeable lemony flavor and medicinal properties. In this study, the antioxidant potential, phenolic profile, and free amino acid profile of lemon verbena infusions from different commercial brands were studied. Characterization by UHPLC-QTOF-HRMS allowed the identification of 34 phenolics. The free amino acid profile (by RP-HPLC-FLD) was assessed for the first time, allowing the quantification of 16 amino acids. Furthermore, the infusions showed high antioxidant activity by different assays (ferric reducing antioxidant power, DPPH• scavenging, and oxygen radical absorbance capacity assays), which in turn were significantly correlated with total phenolics and total flavonoid contents. Notwithstanding, phenylalanine seemed to have also an impact on the antioxidant activity of the infusions, with significant correlations found. Finally, significant differences were found in all the evaluated parameters for one of the four commercial brands herein studied, which was possibly related to the different geographical origins of this sample. Overall, these lemon verbena infusions proved to be rich in a huge variety of bioactive compounds that can provide therapeutic potential.

Abstract:
Stock plants of four vegetatively propagated annual species (Argyranthemum frutescens `Comet Pink', Nemesia fruticans `Plum Sachet' Venten., Osteospermum fruticosum `Zulu' L., and Verbena ×hybrida `Lanai Bright Pink' L.) were grown with one (P), two (PP), or three (PPP) pinches during the scaffold development phase. The number of pinches applied to all four species affected the yield and distribution of cuttings produced over time. P began to produce cuttings first; however, the rate (number of cuttings per week) of cutting production was relatively low resulting in the fewest total cuttings produced by the end of the experiment. Cutting harvest from PPP started 3 to 6 weeks after cuttings were initially harvested from P. However, the rate of increase in cutting production was greater in PPP than P for all species, except Osteospermum, so the total cutting yield of PPP equaled P after 3 to 5 weeks of cutting production. The final cutting yield for PPP was 38%, 38%, 20%, and 8% higher than P for Argyranthemum, Nemesia, Osteospermum, and Verbena, respectively. PP produced 24%, 17%, and 21% more total cuttings than P for Argyranthemum, Nemesia, and Osteospermum, respectively, while Verbena displayed no significant difference. At the termination of the experiment, the weekly rate of cutting production increased 66.3%, 84.0%, and 30.5% as pinch number increased from P to PPP for Argyranthemum, Nemesia, and Verbena, respectively. This study demonstrates that the number of pinches performed on stock plants during scaffold development can have a significant impact on the timing, the weekly production rate, and cumulative yield of cuttings harvested.

Abstract:
The objective was to quantify the effect of supplemental lighting on cutting production for 10 herbaceous annual cultivars. Stock plants of four cultivars (Heliotropium arborescens `Atlantis', Petunia `Supertunia Sun Snow', Scaevola aemula `New Wonder', and Verbena `Tapien Soft Pink') received ambient light [average 6.2 mol·m-2·d-1 photosynthetic photon flux (PPF) during the photoperiod], or ambient light plus either 1.6 or 2.8 mol·m-2·d-1 PPF from high-pressure sodium (HPS) lamps for 11 hours. In a second experiment, the same four species plus six other cultivars were grown under ambient light (average 7.9 mol·m-2·d-1 PPF) or ambient plus 1.9 mol·m-2·d-1 PPF from HPS. The effect of HPS on the production of cuttings varied greatly between species. Growth of Heliotropium was not significantly affected by light level in either experiment. In the first experiment, the addition of 1.6 mol·m-2·d-1 PPF from HPS increased the number of Petunia `Supertunia Sun Snow', Scaevola, and Verbena cuttings by 14%, 51%, and 12%. The addition of 2.8 mol·m-2·d-1 PPF from HPS, increased cuttings harvested from these three species by 23%, 73%, and 22% respectively. In the second experiment, Petunia `Supertunia Sun Snow', Scaevola, Aloysia triphylla (lemon verbena), and Osteospermum `Lemon Symphony' had a positive cutting production response to HPS (17% to 45% increase), whereas cutting numbers of other species (Argyranthemum `Summer Melody', Lantana `Patriot Firewagon', Impatiens New Guinea hybrid `Pedro', Petunia `Supertunia Blue Wren', and Verbena) were not significantly affected by HPS. In both experiments, cutting quality (length, stem caliper, fresh mass, and dry mass) and subsequent rooting of cuttings were not significantly affected by light level.

Abstract:
Abstract Lemon verbena (Lippia citriodora H.B.K., Verbenaceae family) is indigenous to South America and cultivated as an aromatic plant in various parts of world. Lemon thyme (Thymus citriodorus L.), Lamiaceae family, is a perennial medicinal plant native to southern Europe and is cultivated in the Mediterranean region. These species are cultivated mainly for the lemon-like aroma emitted from their leaves due to the presence of dimethyl-2,6- octadienal, also known as lemonal or citral, which is used in food and perfumery for its citrus effect. The aim of this study was to determine the mineral content and essential oil components of L. citriodora and T. citriodorus plants grown under semi-arid climatic conditions in Turkey. The aerial parts of lemon thyme and lemon verbena plants were extracted using hydrodistillation. The essential oil composition was analyzed by gas chromatography-mass spectrometry (GC-MS) and the microelement contents of the herbs were examined via inductively coupled plasmaoptical emission spectrometry (ICP-OES). The microelement contents were 0.249, 1.630, 16.41, 0.106, and 13.1-36.2 mg kg-1 for cadmium (Cd), copper (Cu), iron (Fe), and manganese (Mn), respectively, in lemon thyme, and 0.275, 4.584, 248.1, 15.71, and 1.803 mg kg-1 for Cd, Cu, Fe, Mn, and zinc (Zn), respectively, in lemon verbena. Fifty compounds were identified in lemon verbena essential oil, including limonene (30.33%), trans-citral (17%), cis-citral (12.77%), caryophyllene oxide (5.71%), and geraniol acetate (4.02%) that together constituted 99.86% of the oil composition. We also identified 22 compounds constituting approximately 85.11% of lemon thyme essential oil, including transgeraniol (30.07%), trans-citral (15.06%), cis-citral (11.71%), cis-geraniol (7.65%), and 3-octanol (6.18%).

Abstract:
The objective of this study was to compare the effects of flurprimidol or paclobutrazol on the growth of four bedding plant species: nicotiana (Nicotiana ×sanderae), portulaca (Portulaca grandiflora), verbena (Verbena ×hybrida), and zinnia (Zinnia elegans). Plants were treated 10 days after transplanting with foliar sprays of five concentrations (in mg·L–1): 5, 10, 20, 40, or 80 from each plant growth regulator. Phytotoxicity symptoms were not observed on plants sprayed with flurprimidol or paclobutrazol. Foliar sprays of flurprimidol at 20 mg·L–1 and paclobutrazol at 80 mg·L–1 provided sufficient growth control of nicotiana for retail sales, while concentrations of 40 to 80 mg·L–1 flurprimidol produced more compact plants for wholesale production. For portulaca only flurprimidol sprays of 40 and 80 mg·L–1 produced plants that were proportionate to the container. Foliar sprays of flurprimidol at 20 mg·L–1 and paclobutrazol at 40 mg·L–1 controlled growth of verbena and zinnia suitable for retail sales, while concentrations of 40 mg·L–1 flurprimidol and 80 mg·L–1 paclobutrazol provided more compact plants which may be useful for wholesale growers. Concentrations were based under Florida conditions and should be adjusted for other areas.

The study was planned to determine the chemical composition and antimicrobial properties of the essential oil of Verbena rigida Spreng. cultivated in Egypt. The essential oil from aerial parts of Verbena rigida Spreng. was prepared by hydrodistillation in a yield of 0.26 % v/w. The chemical composition of the essential oil has been elucidated by gas chromatography-mass spectroscopy analysis. The prepared essential oil was tested against selected species of Gram-positive, Gram-negative bacteria and Candida species using disc diffusion method and MICs were determined using broth micro-dilution method. Twenty-eight compounds were identified in the essential oil of Verbena rigida, the major components were isobornyl formate (35.2%) and citral (32.9%). The essential oil showed significant antimicrobial activities against Staphylococcus aureus, Staphylococcus epidermidis, Bacillis subtilis, Escherichia coli and Pseudomonas aeruginosa with MIC 25 µg/mL for E. coli and 50 µg/mL for other sensitive bacteria. This is the first study of the chemical composition and antimicrobial activity of the essential oil of V. rigida, it proved that the essential oil of V. rigida possesses potential antimicrobial properties and could in the future represent a new source of natural antiseptic agents.

Abstract:
Phosphate rock ores, rich in phosphorus (P), are mined in great quantities around the world for the production of P fertilizers. However, availability of phosphate reserves is in question due to decreasing global supplies. Therefore, application of alternative, renewable P sources is of interest. Poultry litter ash (PLA), a byproduct of bioenergy production, contains P concentrations comparable to conventional fertilizers. In this experiment, two P sources, PLA and superphosphate (SP), were compared at two P application rates and two liming rates as fertilizer sources for the production of two commonly-grown greenhouse crops (Verbena canadensis Britton ‘Homestead Purple’ and Lantana camara L.‘New Gold’). Application of PLA produced plants of comparable biomass and quality to those fertilized with SP. Increasing P application rate, across both P sources, increased total flower numbers 42 and 26% for verbena and lantana, respectively. Foliar P concentrations of verbena and lantana increased 27 and 62% for PLA-fertilized plants compared to SP. In addition, substrate pH increased 25% using PLA versus SP. Overall, PLA supplies adequate P fertility and does not reduce pH compared to the more water-soluble, rock phosphate based SP fertilizer.

Abstract:
Abstract The use of native plants enriches the landscape projects, conserves the local flora, creates a local identity and promotes the symbiosis between native fauna and flora. The objective of the present study was to evaluate the vegetative propagation of the native species Calibrachoa sellowiana, Tibouchina dubia and Verbena rigida, using cuttings submitted to different concentrations of indolebutyric acid (IBA), naphthaleneacetic acid (NAA) and substrates. From the stock plants, the cuttings were excised from the apex, with leaves number varying according to the species. In the propagation of Calibrachoa sellowiana, Tibouchina dubia and Verbena rigida under different concentrations of IBA, 4 treatments were carried out, consisting of IBA at concentrations of 0 mg L-1 (control), 500 mg L-1, 1000 mg L-1 and 2,000 mg L-1. In the propagation of Tibouchina dubia under different concentrations of NAA, the experiment was developed using four treatments, NAA was diluted in acetone + talc at concentrations of 0 mg L-1 (control), 2,000 mg L-1, 4,000 mg L-1 and 6,000 mg L-1. The evaluated variables for all the experiments were: percentage of rooted cuttings, number of roots per rooted cutting, average root length (cm) and number of shoots. In the substrate experiment, the treatments were sand, vermiculite, Plantmax® and mixture of soil + sand, for all the species from the previous experiments. Calibrachoa sellowiana and Verbena rigida, rooted with low concentration of IBA, 0 e 500 mg L-1, respectively, but the PGR was not essential to rooting phase, since the control also developed roots. For Tibouchina dubia the IBA and NAA did not promoted rooting. Calibrachoa sellowiana rooted better with soil + sand, differing from Verbena rigida, which rooted better with Plantmax®.

Abstract:
Ethephon [(2-chloroethyl) phosphonic acid] is widely used as a growth regulator in floricultural crop production, with foliar sprays as the typical application method. Ethephon efficacy is determined by rate of uptake and subsequent ethylene evolution, which can be influenced by a number of factors, including solution pH. This study examines whether an ethephon substrate drench (100 mg⋅L−1 at a volume of 296 mL per 2.8-L container) would allow for plant uptake in two herbaceous perennials, Verbena bonariensis (L.) ‘Lollipop’ and Veronica spicata (L.) ‘Goodness Grows’, as measured by subsequent effects on shoot growth and days to flower. We also investigated substrate pH effects on ethephon drench efficacy by analyzing the shoot responses to ethephon applied at a range of starting substrate pH (4.5 to 7.0) compared with untreated plants grown under the same substrate pH conditions (controls). One or more measurements of shoot growth (height, width, shoot dry weight) were reduced in both taxa treated with ethephon as compared with controls. Veronica plant growth was not influenced by substrate pH in either the control or ethephon-drenched plants. For Verbena plants receiving the ethephon drench, as substrate pH increased, height and width increased. For example, when ethephon was applied at substrate pH 4.5, finished plant height averaged 32.0 cm, compared with 43.5 cm for those plants that received the drench at a substrate pH of 7.0. Increasing substrate pH conditions also influenced the days to flower in Verbena plants. Ethephon-treated plants at a substrate pH of 4.5 required an average of 6.5 days longer to flower than those at a substrate pH of 7.0. In summary, ethephon drench applications can result in significant growth regulation effects, as seen in both Veronica and Verbena. Furthermore, increasing substrate pH can reduce the efficacy of ethephon drench applications.

Abstract:
Verbena litoralis, conhecida por gervãozinho-do-campo, dentre outras denominações, é utilizada na medicina popular contra diarreias, desordens gastrointestinais e febres. Recentemente, suas atividades antimicrobiana e antioxidante foram comprovadas. Para auxiliar na sua identificação, o objetivo do presente trabalho foi descrever características anatômicas foliares de V. litoralis. Folhas adultas e expandidas foram coletadas no município de Taubaté-SP. Amostras coletadas do 2º e 3º nós foram fixadas e as secções obtidas à mão livre, com auxílio de lâmina de barbear e isopor foram obtidas no sentido transversal e paradérmico. As lâminas foram preparadas segundo técnicas usuais de anatomia vegetal. As folhas apresentam, em vista frontal da face adaxial, células sinuosas com estômatos anisocíticos, enquanto, na abaxial, estômatos anomocíticos. Tricomas glandulares e tectores unicelulares foram observados em ambas as faces. A nervura central é biconvexa com feixe vascular colateral, o mesofilo dorsiventral com parênquima paliçádico e lacunoso. A região basal do limbo, em vista transversal, apresenta inúmeros tricomas glandulares peltado e subssésis, além de tectores unicelulares, abaixo da epiderme ocorre colênquima angular, o sistema vascular é constituído por um feixe colateral e dois a quatro acessórios. Comparando com dados da literatura, a espécie em estudo se destaca pelas características dos tricomas glandulares.
