Contrary to Lentz et al. (1), I suggested that the sunflower was carried from North America to Europe, not from North America to Mexico. They also misinterpret a number of early documents. In the original Mexican edition of Hernández, Ximénez (2) neither included a drawing of sunflower nor indicated its use by Indians (indios). Hernández called the sunflower chimalacatl and variants, which tran...

Since 1979, the Denver Wildlife Research Center, U.S. Fish and Wildlife Service, has conducted an accelerated research program on the blackbird-sunflower problem which occurs annually in the Dakotas and Minnesota. The objective is to develop effective, cost beneficial and environmentally safe methods for reducing blackbird damage to ripening sunflower. A multidisciplinary approach involving int...

The development of ultra-dense genetic maps has the potential to facilitate detailed comparative genomic analyses and whole genome sequence assemblies. Here we describe the use of a custom Affymetrix GeneChip containing nearly 2.4 million features (25 bp sequences) targeting 86,023 unigenes from sunflower (Helianthus annuus L.) and related species to test for single-feature polymorphisms (SFPs)...

Recently, thermoanalytic methods have frequently been used in the characterization of oils and fats. In this work, thermoanalytic and kinetic parameters of sunflower oils, with and without antioxidants, were evaluated using thermogravimetry / derivative thermogravimetry and differential scanning calorimetry. The thermogravimetric profiles for the sunflower oils had similar characteristics, show...

Dectes texanus LeConte (Coleoptera: Cerambycidae) has become a serious pest of two different crops in the American Midwest, sunflower, Helianthus annuus L. and soybean, Glycines max (L.). Laboratory and field studies were used to compare the effects of these two host plants on D. texanus life history and behavior. Insects from soybean were 40-60% smaller than those from sunflower and larval wei...

Background: Foods have been many changes from production to tables and continuous control is necessary to maintain food safety and supply foods with good quality. The aim of this study was to evaluate the quality of some foods with high consumption in Zanjan city during the 5 years from 2009 to 2013. Methods: In a case-control descriptive study with an annually control program during 5 years f...

Three variations of tomato fudge were prepared using tomato powder at different proportions with sugar, whole milk and honey and evaluated for sensory quality, antioxidant activity, microbial count and consumer acceptability. It was observed that the fudge prepared by using 1-3 g of tomato powder were having higher sensory scores while antioxidant activity was found highest in fudge having 5 g ...

Red-winged blackbird (Agelaiu^ phoeniceus) acceptance of corn as a bait for use in ripening sunflower has been questioned. This study demonstrated that sunflower meats, sunflower achenes, and pearled barley all have potential as alternative bait carriers for 4-AP. Each can be treated with 4-AP so that individual bait particles carry dosages equivalent to those of cracked corn in the registered ...
