OBJECTIVE To validate a 171-item semi-quantitative food-frequency questionnaire (FFQ) for measurement of nutrient intake in an intervention trial based on walnut supplementation. DESIGN AND SETTING Free-living adults from Southern California were randomly assigned to either an intervention (walnut-supplemented) or a control diet. The prescribed 6-month intervention was > or = 28 g of walnuts ...

The genes encoding the insecticidal crystal proteins (ICPs) of BacIllus thuringiensis are good candidates for protecting walnut plants against insect pests. Ve have estimated the dose response of three important walnut pests (codling moth, navel orangeworm and Indianmeal moth) with two highly purified insecticidal proteins of Bacillus thurJ.nglensis and show that these three insects are highly ...

Walnut blackline disease caused by the cherry leafroll virus (CLRV) causes fatal necrosis at the union between English walnut scions and hypersensitive rootstocks. All English walnut cultivars tested so far are susceptible to blackline girdling. A breeding program for developing a blackline resistant Englishwalnut cultivarwas begun in 1983. The time requiredto breed an English walnut cultivar t...

The black walnut, Junglas nigra, is indigenous to eastern North America, and abscission of its fruit occurs around October. The fruit consists of a husk, a hard shell, and kernel. The husk is commonly discarded in processing, though it contains phenolic compounds that exhibit antioxidant and antimicrobial properties. For this study, black walnut husks were extracted using supercritical carbon d...

in the recent years application of allelopathic effects in weeds managment have attracted the attention of many researchers. to study the effects of water extracts and various amount of plants powder of sinapis, achillea, salvia, artemisia and wanut leaf on seed germination and seedling growth of bean, two separate factorial experiments were carried out in completely randomized design, with 3 a...

BACKGROUND Walnut is unique because they have a perfect balance of n-6 and n-3 polyunsaturated fatty acids. The increasing market demand of walnut lipids results in the large amount of the oil extraction residue. The walnut residue is rich in nutritional proteins, and the uneconomic use of the by-product discouraged the development of walnut industry. Anticancer peptides have recently received ...

Walnut (Juglans regia L.) is a well-known member of the Juglandaceae family and its kernel is widely consumed around the world for both unique nutritional characteristics and health-related benefits. Even though several studies investigated the composition and biological activities of different parts of the walnut tree, the internal septum of the walnut kernel is less evaluated. In the...

The Guthion-resistant strain of walnut aphid parasite, Trio x y s p a II i d us. was mass reared in the greenhouse on potted walnut trees and released into five commercial walnut blocks near Colusa, Stockton, Modesto, and Hanford. Parasites successfully established in four of the five sites, surviving on field rates of Guthion and Supracide. The Guthion-resistant strain persisted in the release...
