Fragrant tuberose is the most important scented cut flower of Iran, which rank 4th among other cut flowers, based on the cultivation area and production. Due to the scarcity of water resources, soil constraints, and the aim of comparison and possible substitution of soil cultivation with soilless cultivation of tuberose, a pot experiment was conducted as factorial, based on completely randomize...
Introduction & Objective: With increasing the information about the dangerous side effects of synthetic antibiotics , the demand for natural alternative of these drugs has increased. The purpose of this study is to investigate the antibacterial and antioxidant properties of root and flower extracts of the medicinal plant of Dendrostellera lesserti against some human pathogenic bacteria. Materia...
Sainpaulias are among the most popular flowering plants and there are so many variations in flower shape, size and color. Aqueous solutions of 0 M to 10 M concentrations of salicylic acid (SA) were foliar-applied on two African violet cultivars to evaluate the influence of different rates of SA on growth and flowering of plants. The solutions were applied to leaves of plants 14, 21, 28 and 35 d...
Silicon (Si) is a beneficial element for on plant growth and development that plays an important role in plant resistance to environmental stresses such as salinity and drought. The present research was conducted to study the effect of Si and water deficit on biochemical, physio-morphological and qualitative traits of cut rose cv. Club-Nika under greenhouse conditions. The factorial experimen...
saffron is the most important iranian non oil export. improper conditions of saffron flower storage increases microbial contamination and decreases saffron quality. this study was done for prolonging the shelf life of saffron flower in modified atmosphere packaging and subsequent to producing a new method for exporting the fresh saffron flower as cut flower. saffron flowers were packed in a pol...
The effect of leaf extracts of Psidium guajava and Piper betle on prolonging vase life of cut carnation flowers was studied. "Carola" and "Pallas Orange" carnation flowers, at bud stage, were pulsed 24 hours with a floral preservative. Then, flowers were placed in a vase solution containing sprite and a "germicide" (leaf extracts of P. guajava and P. betle, 8-HQC, or a copper coin). Flowers tre...
The main objective of this study was to determine the effects of vermicompost and amino acids on the qualitative and quantitative yield of chamomile. The experiment was conducted during the growing season of 2010 at the Alborz Medical Research Center. The Treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the sprays of amino acids (budding stag, flowering stage, and bu...
This research was performed to evaluate the effects of foliar application of nano-silicon (NSi), as a quasi-essential element, on yield, flower quality, vase life and infestation percentage of gerbera by greenhouse whitefly. Treatments were preharvest foliar application of different levels of NSi (0, 50 and100 mg/L) on gerbera 'Stanza' in a soilless system (to eliminate the effects of soil's Si...
In order to identify ecotyps of field binweed (Convolvulus arvensis L.), seeds from eight proviences, including 125 populations were gathered and sent to Weed Research Department of Plant Pests & Diseases Research Institute, Tehran, Iran. These seeds planted in a uniform environment condition in Tehran. On the base of 24 morphological and physiological characteristics of seedling that derived f...
this study performed to evaluate genetic diversity of some wild and domesticated (unknown foreign cultivars) blackberries in sanru collection based on morphological traits. results showed high diversity for flowering, ripening time and fruit juice. wild genotypes showed significant differences in leaf, flower, thorn number, fruits and seed fresh weight compared to domesticated cultivars. based ...
