in this paper the separation of saffron stigma from stamen and petal in a vertical wind tunnel has been evaluated. a wind tunnel with adjustable speed of 0.1 m s-1 intervals has been developed and used for the experiments. floating velocities of flower components (petal, stigma and stamen) were measured at one, eight, 38 and 60 hours after harvesting. subsequently, the separation was tested by ...

As an aromatic and colorful plant of substantive taste, saffron (Crocus sativus L.) owes such properties of matter to growing class of the secondary metabolites derived from the carotenoids, apocarotenoids. Regarding the critical role of microRNAs in secondary metabolic synthesis and the limited number of identified miRNAs in C. sativus, on the other hand, one may see the point how the characte...

To develop saffron planting in Urmia, West Azerbaijan, Iran, a split-split plot experiment based on CRBD was carried out in the Urmia University's research farm for two years (2013-14). Nanofertilizers (Fe, P, K and nofertilizer (control)) as main plots, saffron ecotypes (Mashhad, Torbat-Heydarieh, Torbat-jam, Gonabad, Ghaen and Birjand) as subplots and maternal corm weight (6, 8, 10 and 12 g) ...

Worldwide, lung cancer is the most common form of cancer. Saffron has been used in folk medicine for centuries. We investigated the potential of saffron to induce cytotoxic and apoptotic effects in lung cancer cells (A549). We also examined the caspase-dependent pathways activation of saffron-induced apoptosis against the A549 cells. A549 cells were incubated with different concentrations of sa...

Dried stigma of saffron is the most expensive spice in world. In Iran, majority farms use traditional basin method for irrigation, which, together with other irrigation methods may soon face serious problems because droughts future. Making an evaluation regional crop response to important adoption a proper management strategy. this study, effect employing different methods, including sprinkler,...

to evaluate the effect of nano-iron chelate and also to make a comparison with effect of eddha iron chelate on saffron, an experiment was conducted as factorial based on a randomized complete block design with six treatments and three replications in shahed university, tehran in 2011 and 2012. treatments included iron fertilizer (nano chelate and common chelate) in three levels (zero, 450 and 9...

OBJECTIVES Ischemia/reperfusion (I/R) injury of spinal cord is leading to the paraplegia observed. In this study, we investigated the protective effect of the saffron extract on spinal cord I/R injury. MATERIALS AND METHODS Thirty five male Sprague-Dawley rats were divided into 5 groups: intact, sham surgery, normal saline (NS), low dose saffron aqua extract, high dose saffron aqua extract. ...

More and more saffron has been cultivated in China because of the increasing saffron demand, but no paper has studied the influence of drying methods on the quality of Chinese saffron. In this paper, three different dehydration treatments applied in actual production were evaluated: dehydration with electric oven, vacuum oven, and microwave. We determined that the highest quality of saffron wil...

Crocus sativus is the source of saffron spice, the processed stigma which accumulates glucosylated apocarotenoids known as crocins. Crocins are found in the stigmas of other Crocuses, determining the colourations observed from pale yellow to dark red. By contrast, tepals in Crocus species display a wider diversity of colours which range from purple, blue, yellow to white. In this study, we inve...
