the changes in viscoelastic properties of potatoes (tubuls agria) stored at 4 ˚c for 4 months were modeled and evaluated by using the creep-recovery test. cylindrical specimens with 15 mm in diameter and 35 mm long were used. the samples were allowed to deform gradually under the constant stress (110 kpa) for about 30 min. after removing the load, the sample recovery was registered. deformation...

this study was conducted to evaluate different nutrient solutions effects on agria potato mini-tubers production under aeroponic system. the experiment was conducted in the laboratory and greenhouse of ardabil sabalan behparvar company in 2013. four recommended nutrient solutions including: lommen and struik (1992), kang and han (2005), otazu (2010) and hoagland and arnon (1950) were used in a ...

storage of potatoes is very important because fresh potatoes are available only for a few months in a year. thus, any treatment such as irradiation that controls sprout growth and extends shelf life of potatoes could be beneficial. in this study, potato sprout inhibition and tuber quality after treatment with various levels of gamma irradiation (0, 50, 100 and 150 gy) on different dates (10, 30...

Preadult determinants of adult fitness and behaviour have been documented in a variety of organisms with complex life cycles, but little is known about expression patterns of genes underlying these adult traits. We explored the effects of differences in egg-to-adult development time on adult transcriptome and cuticular hydrocarbon variation in order to understand the nature of the genetic corre...

in order to evaluate the effect of rimsulfuron, eptc (eradican), oxadiargyl, metribuzin and metribuzin herbicides for controling of lambsquarter (chenopodium album) and prostrate pigweed (amaranthus retroflexus), an experiment was conducted at the mohaghegh ardabili university green house in 2008. a dose-response assay was conducted based on completely randomized design with four replications. ...

to determine the effects of pre-germinating of tubers and plant density on yield and some agronomic traits of six commercial potato cultivars, an experiment was carried out in ardebil agricultural research station for two years (2001 and 2002). the experiment was in a split split splot on the basis of completely randomized block design with three replications. pre-germination and non pre-germin...

Given the importance of potato in the economy and people’s nutrition, as well as planting of disease-free seeds, it seems necessary to produce healthy seeds through tissue culture. This study was conducted during 2012-2013 at the Research Center of Agricultural University of Tajikistan aiming to evaluate the effect of different sizes of mini-tuber on yield and yield components of potato crop. A...
