Characterization of Resistance to Squash Silverleaf Disorder in Summer Squash
Feeding nymphs of the silverleaf whitefly, Bemisia argentifolii (formerly known as Bemisia tabaci Gennadius, B strain), cause a physiological disorder known as squash silverleaf (SSL) in summer squash (Cucurbita pepo L.). This disorder is characterized by a progressive silvering on the upper leaf surface caused by the development of large air spaces between the palisade mesophyll cells and the ...
متن کاملTransplant Age Influences Summer Squash Growth and Yield
Greenhouse and field experiments were conducted to determine the influence of transplant age on growth and yield of ‘Dixie’ and ‘Senator’ summer squash (Cucurbita pepo L.). Dry weight and leaf area measurements indicated that 28to 35-day-old greenhouse-grown transplants grew more slowly after transplanting than plants that were 10,14, or 21 days old. Older transplants flowered earlier; however,...
متن کاملControl of yellow and purple nutsedge in elevated CO2 environments with glyphosate and halosulfuron
Atmospheric concentrations of carbon dioxide (CO2) have significantly increased over the past century and are expected to continue rising in the future. While elevated levels of CO2 will likely result in higher crop yields, weed growth is also highly likely to increase, which could increase the incidence of herbicide resistant biotypes. An experiment was conducted in 2012 to determine the effec...
متن کاملEvaluation of Imazosulfuron for Yellow Nutsedge (Cyperus esculentus) and Broadleaf Weed Control in Potato
Field studies were conducted in 2007 and 2008 near Nyssa, OR, and Pasco and Paterson, WA to evaluate yellow nutsedge and broadleaf weed control and potato tolerance to imazosulfuron. No injury symptoms from imazosulfuron were evident on potato at Nyssa, whereas in Washington, imazosulfuron caused some chlorosis of potato foliage ranging from 6 to 15% and , 4% at 6 and 15 d after POST applicatio...
متن کاملCombining ability of summer-squash lines with different degrees of parthenocarpy and PRSV-W resistance
The aim was to assess heterosis in a set of 16 summer-squash hybrids, and evaluate the combining capacity of the respective parental lines, which differed as to the degree of parthenocarpy and resistance to PRSV-W (Papaya Ringspot Virus-Watermelon strain). The hybrids were obtained using a partial diallel cross design (4 × 4). The lines of parental group I were 1 = ABX-037G-77-03-05-01-01-bulk,...
