To Select an appropriate medium for the growth of plant is one of the problems of most greenhouse owners in production of pot ornamentals. So, current research was conducted to evaluate effect of some available media in mixtured by perlite on the growth of pothos. Study was based on a completely randomized design with 5 treatments, 8 measuring times and 6 replications in a fiberglass greenhouse of Gorgan University of Agricultural Sciences and Natural Resources during 2009-2010. The treatments include ratios of perlite+ leaf compost, perlite+ rice husk, perlite+ cocopeat, perlite+ composted forest trees and perlite+ mushroom compost. Parameters such as plant height, stem diameter, leaf number, leaf fresh and dry weight and chlorophyll content were measured. Moreover, plants were compared according to their overall shape and appearance. The results of data analysis showed that the effect of medium, measuring time and their interaction were significant in all traits. The marketing val...

Mulches bring several benefits to lettuce cultivation.A study on the lettuce ‘Red Rapids’ has been conducted to determine the influence of the different colored plastic mulch on its growth. The experiment consisted of five color treatments as follows; treatment 1- metallic silver (control), treatment 2- red, treatment 3- orange, treatment 4- yellow and treatment 5green. Results showed that the colored mulch treatments had significant influenced on the different parameters including: root length at harvest, average leaf length, leaf diameter, plant height, plant weight, number of leaves at harvest and percentage survival. Lettuce grown in red mulch had significantly outperformed the other colored treatments.

During this experiment, the effects of cow manure and cow manure + sawdust vermicompost replacement instead of peat in the growth media were investigated on the growth of ornamental foliage plants Aglaonema (Chinese evergreen), Dracaena marginata and Spathiphyllum wallisii. To produce vermicompost, cow manure and cow manure + sawdust (volume ratio 80 to 20) was added to Eisenia fetida earthworm medium. After preparation of vermicomposts for preparation of growth media, volumetric values of 25, 50, 75, and 100% vermicompost of cow manure and cow manure + sawdust replaced peat in the control (peat + perlite with a volume ratio of 2 to 1). After preparing the growth media, rooted cuttings were planted in them. Measured factors were nitrogen, potassium, calcium and magnesium in leaves and growth medium, height, diameter, fresh weight of stems and leaves, dry weight of stems and leaves and fresh and dry weight of plant roots. The results showed that increasing the levels of two types of vermicompost in peat replacement increased nitrogen, phosphorus, potassium, calcium and magnesium of the leaves in Aglaonema, Dracaena marginata and Spathiphyllumwallisii. With increasing two types of vermicompost in the growth medium, water holding capacity increased compared to peat and 100% vermicompost had the highest water holding capacity. Application of 25% of each vermicompost increased the height, diameter, fresh weight and dry weight of branches and leaves in plants compared to the control. Due to the problems caused by the accumulation of sawdust in the environment and the high cost of peat in the ornamental plant industry, the use of 25% cow manure + sawdust vermicompost is a more economical recommendation.

Different extraction methods (organic solvent and water extraction with the assistance of heat or ultrasound) were investigated for their effects on the phytochemical profile and antioxidant activity of Clitoria ternatea flowers. For solvent extraction (30%, 50%, 80%, or 100% methanol, ethanol, or acetone), 50% ethanol was considered to be the best solvent for the extraction with an extract yield of 57.3%, a total anthocyanin content of 5.1 mg of cyanidin 3-glucoside equivalent/g of dry weight of extract, and a total phenolic content of 59.4 mg of gallic acid equivalent/g of dry weight of extract. Similar results were obtained for the best water extract at 50°C for 1 h. A larger number of phytochemicals were identified using LC-MS analysis in the solvent extract (28 compounds). Kaempferol hexosyl-rhamnosyl-rhamnoside was the major compound detected in both the solvent and the water extract. Both extracts showed equally potent antioxidant activity in chemical [IC 50 = 1.24 ± 0.05 (solvent extract) and 1.18 ± 0.07 (water extract) mg/mL in the 2,2-diphenyl-1-picryl-hydrazyl-hydrate assay] and cellular (75−80% inhibition) antioxidant assays.

Colletotrichum gloeosporioides is the causal agent of anthracnose disease of several fruits such as mango, papaya and avocado affecting both its pre-and post-harvest quality. This economically-important fungal disease is usually controlled by synthetic fungicides causing an increase in the production cost of the mango growers. The utilization of chemical pesticides is widely common due to its effectiveness, convenience, and availability in the market however, the abusive use of these synthetic chemicals posed harmful effects to environment and living organisms including humans. Hence, exploration of botanical pesticides with pesticidal properties is being investigated worldwide as an ecofriendly substitute for synthetic chemicals. The aqueous and ethanolic plant extract derived from leaves of marigold (Tagetes patula), lantana (Lantana camara), tamarind (Tamarindus indica), and cosmos (Cosmos sulphureus) were tested against C. gloeosporioides. Results showed that all aqueous extracts did not show any inhibitory effects on the growth of the test fungus in-vitro when compared to the negative (sterile distilled water)and positive (fungicide) control. No reduction in the radial growth of the fungus suggested that the tested aqueous plant extracts were non-fungicidal against the pathogen. However, it was observed that ethanolic extracts from tamarind and marigold showed 42% and 34% inhibition, respectively. These two ethanolic extracts can be further tested in-vivo using different mode of inoculation and application to elucidate their antifungal action.

Rose breeders need reliable and efficient germination protocols to exploit all viable embryos in their breeding programme. A combined physical restriction of the seed coat and a physiological dormancy are present in the achenes of hybrid tea roses resulting in variable and not uniform seed germination. In this study, different treatment combinations were assessed to overcome the mechanical resistence of the pericarp and enhance germination. Both chemical and microbial seed scarification were carried out. A mild scarification with sodium hypochlorite (NaOCl) before stratification promoted a more uniform germination and enhanced the percentage of germination from 49.2% to 65.9%. Epiphytic bacteria, Emercal (TM) (a product composed by bacteria and co-metabolites produced by bacterial fermentation), or Remedier (R) (a commercial formulation of Trichoderma harzianum and Trichoderma viridae), added to the stratification sand, enhanced percentage of germinated seeds but had no effect on th...

The most widespread invasive alien plant species in South Africa’s Kruger National Park (KNP) were either introduced unintentionally along rivers and roads, or intentionally for use as ornamentals. We examine the spatial distribution of ornamental alien plants in KNP, look at the link between human population size, history, and species richness, and show how the distribution of particular species reflects the likely history of ornamental plantings. Results are used to assess whether past management actions have been appropriately directed. Two hundred and fifty-eight alien species have been recorded in the 36 tourist camps and staff villages. The number of staff housed in villages explains much of the diversity of cultivated alien plant species. Older camps also tend to have more ornamental alien plant species. However, the lack of a strong link between camp age and number of cultivated species suggests that ornamental plants have been widely spread around the KNP by humans. We also show that increased camp activity (either size or age) has led to more ornamental species, while, with the notable exception of Skukuza, camp activity has had a much smaller effect on the number of noncultivated species. Noncultivated species tend to be naturally dispersed, as opposed to directly spread by humans between camps. Past management prioritized certain species on the basis of their potential to invade KNP and on the prevailing national legislation. These species were removed manually and follow-up control was carried out. Once the priority species were deemed to be under control, less invasive species were targeted. All alien species were removed from vacated houses, regardless of the potential invasiveness of the species.

Gas chromatography-flame ionisation detection (GC-FID) and gas chromatography–mass spectrometry (GC–MS) analyses of the essential oils of leaves and fruits of the ornamental Shinus molle L. were reported and their allelopathic effect on wheat (Triticum aestivum L.) was evaluated. Qualitative and quantitative differences between fruit and leaf oils were observed. Both oils were rich in monoterpene hydrocarbons and the major constituents were limonene and β-phellendrene (35.9–65.4%), α-phellendrene (24.3–20.1%), myrcene (12.8–7.7%) and α-pinene (5.9–1.7%) for fruits and leaves, respectively. Both essential oils showed a dose-dependent allelopathic activity on wheat germination and radicle elongation with leaf oil being the more phytotoxic.

Bir kenti oluşturan en önemli ögelerden biri de kamu kurum ve kuruluşlarıdır. Çeşitli
kurumlara ait binaların kent içinde önemli sayıda yer aldığı düşünüldüğünde, bu binaların kullanımında bulunan dış mekanların da kent yapısında ne denli büyük rol oynadığı ortaya çıkmaktadır. Bu alanlar kent yaşamına hem ekolojik hem de estetik boyutta farklı kazanımlar sağlamaktadır. Kurumların verdikleri hizmetle bağlantılı olarak dış mekan özellikleri konusunda beklentileri çok çeşitli olabilmektedir. Örneğin; bir hastane bahçesi ile bir okul bahçesinin gerektirdiği detaylar bazı noktalarda birleşirken bazı kullanımlarda ise oldukça farklı olabilmektedir. Kamu binalarının dış mekanları tasarlanırken ekolojik, sosyal, ergonomik ve psikolojik tüm boyutlarıyla ele alınmalıdır. Ayrıca bu alanların kent yaşamına görsel katkı sağlaması da gereklidir. Ancak genel yaklaşım ne yazık ki bina yapımı tamamlandıktan sonra kalan alana birkaç bitki dikilmesiyle sınırlı olmaktadır. Dolayısıyla kamu binalarının dış mekan özellikleri, bu kurumlardan hizmet alan bireylerin ve buralarda görev yapanların kullanıcı olarak beklentilerini karşılayamamaktadır. Çalışmada Çanakkale kent merkezindeki bazı kamu binalarının dış mekanları irdelenmiş, kullanım yeterlilikleri saptanmıştır. Ayrıca saptanan eksik noktaların tamamlanmasına ve yanlış uygulamaların çözümüne yönelik çeşitli yaklaşımlar ortaya konulmuştur. Anahtar kelimeler: Açık-yeşil alan sistemi, kamu binaları dış mekanları, Çanakkale Valiliği, Çanakkale Devlet Hastanesi

The goal of this paper is to implement modern, up-to-date, geomatics technique and technologies in the environment. The base is made in GIS software, a GPS device is used to record detailed points on the field and for recording and preparing a new orthophoto was used a modern sophisticated drone DJI Mavic Pro. QGIS (Quantum Geographic Information System), as a key software, was used for computer data processing and recordings obtained from the field research, and other utility programs were used to perform the tasks. The subject of the article is the Kumanovo city promenade in Macedonia, which is a convenient place to try to implement this data processing method. The results obtained give us a map of the entire urban dendroflora on the river bank in the city of Kumanovo. In fact, an inventory of all trees and shrubs was carried out, 4 projections were prepared with the help of modern applications, and as the ultimate goal, and a web digital map of the riverbank was prepared. This method can be applied in forestry, agriculture, water management, geodesy, space planning, sustainable development and environmental protection.

The present study was conducted to find out the role of Consolida ambigua and Calendula officinalis L. ornamental plants along with Kocuria rhizophila bacterium in phytoremediation of the nickel contaminated soil. One group of ornamental plants was grown in control environment (C), while the other groups were subjected to stress conditions i.e., Treatment with Bacteria (T1), Treatment with Bacteria þ Chelator (T2) and Treatment with Chelator (T3). Nickel Chloride (100 mg/kg) and citric acid (5 mM) were applied when the plant species started its normal photosynthetic activity. Preliminary results showed that plant biomass i.e., plant height (cm), fresh and dry weights (g), proline content (mg/g) and photosynthetic pigments (mg/g) were significantly increased with co-application of bacteria and citric acid as compared to non-inoculated and inoculated plant species. The growth pattern observed in order of T2 > T1 > T3 > C. The statistical significant growth with T2 at p 0.05 suggested the role of Consolida ambigua and Calendula officinalis L. ornamental plants in association with Kocuria rhizophila bacterium were beneficial for phyto-extraction purposes. It was concluded that the aforementioned plants can safely be grown for phytoremediation purposes to reduce soil pollution in term of heavy metal accumulation.

Surveys of Impatiens and Verbena species in local nurseries in Fredericton, Canada and Verbena species in New Delhi, India showed widespread infection of Citrus exocortis viroid (CEVd) in vegetatively-propagated and seed-grown plants. To determine viroid seed transmission, samples of eight varieties of Impatiens and 11 varieties of Verbena were obtained from four commercial sources. All 19 samples collected contained viroid infection irrespective of variety. The presence of viroid in non-germinated seed was 21%, while the transmission rate in seedlings was 66% in Impatiens walleriana in 2006. Following 2 years of seed storage, the respective figures were 6% and 26%. Similarly, in Verbena x hybrida the presence of viroid in seed was 13% in 2006 with a seed-transmission rate in seedlings of 28%, while the respective figures after 2 years of storage were 5% and 45%.

Phytophagous mites living on ornamental plants growing in parks, streets and residential gardens from Ilha Solteira, State of São Paulo, were studied. Leaves of 20 plant species were sampled and some specimens of the different morphospecies found were mounted in microscopy slides with Hoyer's medium for posterior identification under phase contrast microscope. Twenty three species belonging to 15 genera of eight families were recorded. From these, 13 species are phytophagous, nine are predator and one is of unknown feeding habits. The family Tetranychidae presented the highest richness, with nine species registered, being one of these recorded for the first time after the original description and another one being registered for the first time in Brazil. Lorryia formosa Cooremann, 1958 (Tydeidae) occurred on the highest number of hosts. The host plants that harbored the highest number of mite species were Lagerstroemia indica L., Mussaenda alicia Hort. and Tabebuia sp., with six species recorded on each.
