This study reports the optimised conditions (temperature, ethanol concentration and processing-time) for antioxidant extraction from potato peel (Agria variety) waste. At short extraction times (34 min), optimal yields of phenolic (TP) and flavonoid (Fv) compounds were reached at 89.9°C and ethanol concentrations of 71.2% and 38.6%, respectively. The main phenolic compounds identified in the ex...

the cultivar khavaran has come out of the national potato breeding program started in 2001 and continued for ten years in the seed and plant improvement institute karaj, iran. the breeding methodology has initiated by selection among germplasm consisting an open pollination of the clone 397097-13. the khavaran release included single plant selection, visual assessment, preliminary observation n...

In this research, the acclimatized in vitro plants were transferred to the aeroponic system and the effects of paclobutrazol (PBZ) and jasmonic acid (JA) were investigated on the production of potato (Solanum tuberosum L. cvs Agria and Svalan) minitubers. Some plant characteristics were also investigated in this cultivation system, under greenhouse conditions. Plants were foliar sprayed with PB...

potato is one of the most productive crops in agriculture and is a valuable food source in developing countries. mycorrhizal fungi involve a symbiosis with most of crop roots and leads to improve the crops growth and yield. in order to investigate the effect of mycorrhiza fungi species on yield of potato cultivars a factorial experiment was arranged in a randomized complete block design with ei...

to shorten the dormancy period of potato minitubers and to increase a tuber's capacity to be planted sooner after being harvested, an experiment was conducted at pishtaz tissue culture company in karaj, using factorial experiment on the basis of a completely randomized design with three replications. the first factor was comprised of cultivars (agria, marfona and burren), the second minitu...

introduction in recent years, rainfall deficiency was an increasing problem in most countries; which limited the production of agricultural crops. among abiotic stresses the plants encountered, drought stress is considered as the most important limiting factor in plants growth and reproduction in natural and agricultural systems through most parts of the world; while drought stress causes 45% i...
