background & aim: the pigments inside the leaf chloroplasts receive sunlight energy and transport it to photosynthesis reaction center. the most important of these pigments is chlorophyll. in this study, the pigments existence in medicinal plant, sumac (rhus coriaria l.), was investigated at biotechnology laboratory, isfahan university of technology. experimental: experiments were performed...

A library cataloguing the electron paramagnetic resonance (EPR) spectra of artists’ pigments has been created. It contains spectral data collected using several spectrometers that operate at different frequencies for, currently, 51 pigments. The is intended to serve as an open-access reference database for scientific studies cultural heritage objects utilize this analytical technique. Furthermo...

o investigate the role of selenomethionine (SeMet) in regulating drought tolerance strawberry plants, we explored effects SeMet on antioxidative enzymes, water physiology and fruit quality plants under stress (DS). In this study, used variety ‘Sweet Charlie’ as material investigated through foliar spraying pot experiments. The results showed that DS obviously enhanced activities antioxidant enz...

Objective: In the present study described here, we set out to look into quorum sensing inhibitory activity of methanolic seed extract Berberis crataegina DC. through -controlled inhibition violacein pigment production in Chromobacterium violaceum ATCC 12472. addition, antibacterial on various Gram-negative and Gram-positive standard strains was evaluated. Also phenolic contents were detected by...

As the periodic emission of light pulses by emitting diodes (LEDs) is known to stimulate growth or induce high value biocompounds in microalgae, this flashing regime was tested on and biochemical composition microalgae Nannochloropsis gaditana, Koliella antarctica Tetraselmis chui. At low frequencies (e.g., 5 50 Hz, Duty cycle = 0.05), a strain-dependent inhibition an accumulation protein, poly...

background and objectives:hormozgan province is located in the south of iran, bordering waters of the persian gulf and oman sea. due to the antioxidant potential of plants which might be responsible for their medicinal properties, the antioxidant properties of four medicinal plants of the region were evaluated. methods: the antioxidant properties of chrozophora obliqua, daphne mucronata, salvia...

This study was conducted to determine the effects of growth regulator prohexadione calcium (Pro-Ca) and inhibitor gibberellic acid on some parameters (yield, pigment levels leaves, nutrient contents, proline, enzyme activities fruit quality) when applied at different doses (0, 15, 30, 45, 60 mg L-1). Chemicals were after transplanting seedlings. A total 12 plots including 3 plants for each dose...
