, because most fruit trees and many vegetables are grafted ( Lee, 1994 ). So we grafted potato ( Solanum tuberosum L.) scions onto Me tomato rootstock to test whether the RNA molecule can move from Me tomato and whether it alters the potato leaf

Potato response to water stress and changes in soil available-N levels in relation to irrigation management were evaluated in 1992, 1993, and 1994. Potatoes were grown on silt loam with sprinkler irrigation in an adequately irrigated check (100% of crop evapotranspiration replaced at –60 kPa) and three deficit irrigation regimes. Water stress treatments were achieved by partial or complete replacement of crop evapotranspiration when soil water potential reached –80 kPa. In 1992 and 1994, relatively warm years, tuber yield and grade were significantly reduced by water stress. In 1993, a relatively cool year, yield was reduced by water stress, but grade was not. Each year, soil available-N accounting for the season showed large surpluses for all treatments. Potato cultivars grown as subplots varied in their response to deficit irrigation.

Potato ( Solanum tuberosum L.) was domesticated in the Andes Mountains of South America ( Spooner et al., 2006 ). At the time of European contact, potato was and continues to be a staple of the numerous societies living in the Andes. Potato was

Potato ( Solanum tuberosum L.) is an annual dicotyledonous herbaceous tuber crop that grows best in cool temperate climates under full sunlight, moderate daytime temperatures, and cool nights ( Hawkes and Harris, 1992 ). However, potato plants are

Wisconsin is ranked fourth in U.S. potato production, behind Idaho, Washington, and North Dakota, with 63,500 acres planted in 2009 [ U.S. Department of Agriculture (USDA), 2010a ]. The 2009 U.S. potato crop was worth $3.52 billion, and potato

The main quality defect in fresh-cut potato is enzymatic browning that develops on the cut surfaces of the tissue. Peeling and slicing of tubers cause cellular disruption leading to decompartmentalization of substrates and enzymes ( Brecht et al
