in this research, the effects of thidiazuron pulse treatment and salicylic acid were examined to improve vase life and maintain the quality of alstroemeria ҅modena҆ cut flowers. the experiment was done in a factorial experiment based on rcd with 16 treatments, 3 replications and 48 plots. the flowers were placed in different concentrations of thidiazuron (0, 10, 20, and 50 μm) and salicylic acid ...

Hydrostatic pressure may affect the intracellular pH of microorganisms by (i) enhancing the dissociation of weak organic acids and (ii) increasing the permeability of the cytoplasmic membrane and inactivation of enzymes required for pH homeostasis. The internal pHs of Lactococcus lactis and Lactobacillus plantarum during and after pressure treatment at 200 and 300 MPa and at pH values ranging f...

The effects of savory, caraway, and rose extracts and 8-HQS were studied on the vase life of Alstroemeria cut flowers. The plant extracts at three levels (10, 20, and 40 %), 8-HQS at three levels (100, 200, and 300 mg l-1), and control (distilled water) with 3 % sucrose were continuously applied on the basis of a Completely Randomized Design with three replications. It was f...

the effects of salicylic acid (sa) and putrescine (put), on cut gladioluswas studied. sa (0, 150, 300 and 450 mg l-1) and put (0, 100, 200 and 300 mg l-1), their combinations were tested as preservative mixture. this study was conducted in a factorial experiment with complete randomized design on 192 gladioluscut flowers in horticulture laboratory of agriculture faculty of islamic azad universi...

  The involvement of nitric oxide (NO) in the reinforcing properties of opioids was studied by examining the effect of a NO precursor (L-arginine) and NO synthase inhibitor (L-nitro-amino-methyl-ester, L-NAME) on the conditioned place preference (CPP) induced by morphine. The experiment was performed on male albino Swiss- White mice (25 ± 5 g). L-arginine in doses of 100, 200 and 500 mg/kg (i.p...

experiments were carried out in a commercial orchard during 1994, 1995 and 1996 to determine the influence of chemical thinning on characterisics of fruit and alternate bearing of native olive (olea europea l) cvs. dezfoul and fishomi at early fruitlet stage. in 1994, branch sprays of naphthalene acetic acid (100, 150 and 200 mg/l), naphthalene acetamide (200 and 300 mg/l) and urea (0.6 and 1.2...

Ibuprofen is an effective, cheap, and frequently used non-steroidal anti-inflammatory drug. The present study investigated the doseand time-dependent effects of ibuprofen on hepatic, renal, and hematological functions in rats. Groups of rats (n=6) were given ibuprofen (20, 40 mgkg -1 day -1 ) for 7, 14 or 28 days; or vehicle (control), orally. Blood samples were obtained, and hematological indi...

objective: to evaluate the effect of chemical stimuli on germination and seedling growth of caper (capparis spinosa) under drought stress. methods: factorial experiment in a completely randomized design with four replicates per treatment were performed. first factor of priming include three levels of acetylsalicylic acid (300, 200 and 100 mg/l), gibberellic acid levels (500, 250 and 125 ppm), a...

The aims of the present study were to investigate the effect of Gokshura and nettle root extracts on growth rate and sex reversal in Convict cichlid fish. Seven-day hatchlings were immersed in water containing 0 (Control, T1), 200 mg/l nettle root extract (T2), 300 mg/l nettle root extract (T3), 10 mg/l Gokshura extract (T4) and 10 mg/l Gokshura plus 200 mg/l nettle root extracts (T5) for two m...
