Foliar resistance of two potato clones was tested against a Columbia Basin field population (CBFP) and a Colorado laboratory colony (COLC) of the potato tuberworm, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae). The first clone was a cross of a cultivated potato, Solanum tuberosum L. (Solanales: Solanaceae), and a wild potato, Solanum berthaultii Hawkes (Q 174-2); the second clone ...

SHMT, EC 2.1.2.1, catalyzes the interconversion of Ser and Gly accompanied by the production or consumption of one-carbon units. In leaves it is a component of the photorespiratory pathway (Keys et al., 1978). The main function of that pathway is the salvage of reduced carbon and nitrogen withdrawn from the Calvin cycle by the oxygenation of ribulose 1,5-bisphosphate. By the cooFeration of SHMT...

The ability of Fusarium oxysporum Schlect. to cause a rot of the potato tuber has been clearly demonstrated by a number of workers. The influence of temperature on this disease has been reported in a number of papers, but the experimental evidence as a whole is rather meager, usually only extreme temperatures being used. The effect of moisture on the progress of the disease, except under condit...

Objectives: Potato (Solanum tuberosum L.), as a whole food, contains high levels of vitamins and important antioxidants including phenolic acids, carotenoids and flavonoids. The objective of this study was to determine the total phenolic content and antioxidant activities of three common potatoes (Solanum tuberosum) cultivars in Iran i.e., Savalan, Agria and Sante. Materials and Methods: Pheno...
