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 ...

15 صفحه اولTransplant 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 کاملEarly effects of boron deficiency on indoleacetic Acid oxidase levels of squash root tips.
The indoleacetic acid (IAA) oxidase activity of root tips of boron-sufficient, -deficient, recovering, and IAA-treated boron-sufficient squash plants (Cucurbita pepo L.) was determined. Apical and subapical root sections displayed an increase in IAA oxidase activity between 6 and 9 hours after boron was withheld, and after 24 hours the activity of the apical sections showed a 20-fold increase o...
متن کاملEffects of climate change and cultivar on summer maize phenology
To identify countermeasures to the effects of climate warming on crop production, we mustunderstand the changes in crop phenology and the relationships between phenology and climatechange and cultivar. We used summer maize phenological and climate data in the North ChinaPlain, collected from 1981 to 2010. This study analyzed the spatiotemporal trends inphenological data and lengths of different...
