Like many plant RNA viruses, infection by potato spindle tuber viroid (PSTVd) is known to lead to RNA silencing and a marked reduction in visible disease. To examine the relationship between RNA silencing and this recovery phenomenon in greater detail, we have carried out time-course analyses of viroid-specific small RNA accumulation using several viroid—host combinations. These analyses reveal...

The Colorado potato beetle, Leptinotarsa decemlineata (Say) Order Coleoptera and the potato leafhopper, Empoasca fabae (Harris) Order Homoptera, are the major insect pests of potato in eastern North America. In two years of field trials, we compared the effectiveness of three pest management options for the control of Colorado potato beetle and potato leafhopper: natural host plant resistance (...

understanding people’s ecological behaviors and the impacts of human activities on natural environment is one of the most important concepts in ecological psychology research. the purpose of this study was to investigate causal relationship between factors and maize growers’ ecological behavior concerning the application of external inputs such as water, fertilizers, chemical pesticides, and ma...

Potato Genebank of the Universidad Austral de Chile (UACh) is an important gene bank in Chile. The accessions collected all over the country possess high genetic diversity, present interesting agronomic and cooking traits, and show resistance to biotic and abiotic stress. A particularly interesting subgroup of the gene bank includes the accessions collected in the South of Chile, the Chilota Po...

Cropping sequence and length of rotation play an important role in potato production. Too often, growers are forced to base their cropping system decisions on short-term economic survival. Our market-based economy rewards economic efficiency and has helped push the trend to larger farms with lower production costs. Improving economic efficiency, with large, specialized potato equipment, means f...

We assess consumer demand for traditional fresh potatoes and processed potato products and willingness to pay for new experimental low-acrylamide and sulfite-free potato products. Demand for fresh potatoes, potato chips, and fries is unaffected by household income or education, but demand for chips and fries is affected by consumer age and exercise habits. Subjects display increased willingness...

ized research and development journals, and provide relevant information proactively by the societies, such as Potato Research by the European Association for Potato Research (EAPR, www.eapr.net) under EUCARPIA and the American Journal of Potato Research by the Potato Association of America (PAA, http://potatoassociation.org), however, a wide range of plant science audiences would be interested...

Background: Spine gourd (Momordica dioica Roxb. Willd) is one of the important cucurbitaceous crops grown across the world for vegetable and medicinal purposes. Diseases caused by the DNA viruses are becoming the limiting factors for the production of spine gourd reducing its potential yield. For the commercial cultivation of the spine gourd, propagation material used by most o...

Knowledge of temperature effects on whole canopy photosynthesis, growth, and development of potato (Solanum tuberosum L.) is important for crop model development and evaluation. The objective of this study was to quantify the effects of temperature on canopy photosynthesis, development, growth, and partitioning of potato cv. Atlantic under elevated atmospheric CO2 concentration (700 mL L 21 CO2...
