The abscission of Alstroemeria petals is the serious problem at the industry of cut flowers of this plant. In this study, cut Alstroemeria cv. Bridal flowers were pulsed with solutions containing natural essential oil carvacrol, gibberellic acid and benzyladenine (50 and 100 mg L-1), -5-sulfosalicylic acid (1 and 1.5 mM) and sucrose (5 and 10%) for 24 hours. The distilled water was used as cont...

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 ...

The postharvest life of cut Eustoma grandiflorum flowers is limited in open flowers. Therefore a factorial experiment based on a completely randomized design with ascorbic acid (AsA) at 4 levels (0, 100, 200, 300mg L-1) and citric acid (CA) at 3 levels (0, 100, 200 mg L-1) with 3 replications and 3 samples for each replications, was conducted for this purpose. Results indicated that a significa...

tuberose (polianthes tuberosa l.) is an important commercial cut flower that has a short vase life. an experiment was carried out by using five different levels of humic acid (ha) (0, 25, 50, 75, and 100 mg l-1) and seven different levels of silver nano-particles (snp) (0, 0.5, 1, 2, 3, 4 and 5 mg l-1) mixed with 1.5% sucrose on cut tuberosa cv. single flower. the loss of fresh weight on third ...

OBJECTIVE The objectives of this study were to evaluate the microtensile bond strength (μTBS) of one-step self-etch adhesive systems to Er:YAG laser-irradiated and bur-cut dentin after water storage and thermocycling. BACKGROUND DATA The Er:YAG laser is a promising alternative method for cavity preparation; however, no study has compared the effect of laser irradiation and aging procedures on...

An experimental investigation has been carried out to study the flow regimes and pressure gradients of air-oil-water three-phase flows in 2.25 ID horizontal pipe at different flow conditions. The effects of water cuts, liquid and gas velocities on flow patterns and pressure gradients have been studied. The experiments have been conducted at 20 °C using low viscosity Safrasol D80 oil, tap water ...

This study investigated the role of extracellular cellulose production by Shiga toxin-producing Escherichia coli (STEC) on attachment to lettuce and spinach in different water hardness environments. Two cellulose-producing wild-type STEC strains, 19 (O5:H-) and 49 (O103:H2), and their cellulose-deficient derivatives were used. Strain 49 also produced colanic acid as a constituent of its extrace...

salicylic acid (sa) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. the physiological mechanism of exogenous sa to affect the senescence of cut lisianthus flowers during vase life was investigated. fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mm sa and then held at 25◦c up to 12 days. ...

the effects of salicylic acid (sa) and putrescine (put), on cut narcissus was studied. sa (0, 100 and 200 mg l-1) and put (0, 150 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 108 narcissus cut flowers in horticulture laboratory of agriculture faculty of islamic azad university, jiro...

Herbivory can affect plant carbon gain directly by removing photosynthetic leaf tissue and indirectly by inducing the production of costly defensive compounds or disrupting the movement of water and nutrients. The indirect effects of herbivory on carbon and water fluxes of soybean leaves were investigated using gas exchange, chlorophyll fluorescence and thermal imaging. Herbivory by Popillia ja...
