In addition to common vegetative multiplication, potato crop can be reproduced by true potato seed (TPS). Only the limited number of pests and diseases, which are the most important causes of a decrease in potato production, can be transmitted by true potato seed. Hence, to evaluate the potential of true potato seed in comparison to potato seed tuber and mini tuber, an experiment was conducted ...
Potato (Solanum tuberosum L.) has relatively weak root system and requires high nitrogen fertilizer which is costly and may pose environmental pollution. This study was conducted to compare root morphological characteristics and nitrogen uptake of some potato cultivars growing in Iran. A greenhouse experiment using a completely randomized design with 3 replications and 8 potato cultivars includ...
the use of nitrogen in nutrient media is essential for growth and helps identify highly productive media for potato (solanum tuberosum l.) micropropagation and adventitious shoot formation. three potato cultivars (agria, marfona and savalan cultivars) were examined for their growth response with medium containing four different levels of kno3 (1, 1.25, 1.5 and 1.75 times as much 1.9 g l-1) and ...

Physicochemical characteristics of potato (Solanum tuberosum L.) are very important for storage and processing qualities. The amount of reducing sugars (glucose and fructose) and organic acids at harvest, during and after storage is the most important factor. In this study, three potato cultivars (Moran, Marfona and Agria) were collected, dry cleaned and graded into three sizes. They were analy...
This study was carried out to evaluate the effects of salicylic acid in Marfona potato cultivar (Solanum tuberosum L.) for reducing the pathogenesis of Rizoctonia solani in potato tubers under greenhouse conditions. The pots sterilized soils had been infected by R. solani (21B1 strain) two weeks before transplanting the potato plantlets. The seedlings were treated with 0 (control), 0.1, 0.2, 0....
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...
In order to investigate the effect of different levels of biological fertilizers on potato performance (cv. Marfona), an experiment was carried out as strip plot based on RCB design with 3 replications in 2011 at Isfahan. Treatments included Nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and Nitroxin+ Phosphate at 4 levels (0+0: control, 20+100, 30+150...
