The Colorado wild potato (Solanum jamesii) is the only species among more than 100 different kinds of plants that the writer (6) has irradiated in which a plant organ has made greater growth leading to increased weight as a result of the treatment. The growth and development of the underground parts of 22 species (7) exposed to medium doses showed detrimental effects to adventitious, fibrous, a...

a factorial experiment based on a randomized complete block design with three replications was carried out in order to study the effects of tuber size, nitrogen fertilizer and harvest date on yield and yield components of potato. this experiment was conducted in a grower’s farm in uraki village located in chabahar city, in 2011. in this experiment, the treatments were two levels of tuber size (...

background: p. atrosepticum is a commercially important pathogen. it causes blackleg in the field and soft rot of tubers after the harvest. this effect is due to secretion of depolymerases and other virulence factors by several mechanisms including t3ss objectives: the effect of bacterial t3ss on solanum tuberosum (s. tuberosum) varieties and its relationship with s. tuberosum resistance gene e...

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...

Near-infrared (NIR) diffuse reflectance has been extensively and successfully applied on quality assurance for fruits, vegetables, and food products. This study is principally aimed to extract the primary wavelengths related to the prediction of glucose and sucrose for potato tubers (of Frito Lay 1879 (FL), a chipping cultivar, and Russet Norkotah (RN), a table use cultivar, and investigating t...

An investigation was carried out to reveal the changes in the concentration of soluble carbohydrates under tuber dormancy in food yam (Dioscorea esculenta) tubers and in an economically important spice cum medicinal plant turmeric (Curcuma longa) rhizomes under storage. Harvested, fully matured tubers of yam and rhizomes of turmeric were stored in wooden boxes under the conditions of 28 ? 2?C t...

3.5 ha of sweet potato were used to feed 30 crossbred Brahman bulls with an average weight of 184 kg and approximately one year old in an experiment to study the use of sweet potato in beef production. The five treatments were allocated to the experimental units in an unrestricted randomized block design. Treatments contained 0:100, 25:75, 75:25, 50:50 ant 100:0 ratios of tubers to sweet potato...

Heterotrophic carbon metabolism has been demonstrated to be limited by oxygen availability in a variety of plant tissues, which in turn inevitably affects the adenylate status. To study the effect of altering adenylate energy metabolism, without changing the oxygen supply, we expressed a plastidially targeted ATP/ADP hydrolyzing phosphatase (apyrase) in tubers of growing potato (Solanum tuberos...
