'Jones Hybrid' hickory is an accession in the National Collection of Genetic Resources for Pecans and Hickories for which information about origin, identity and characteristics is very incomplete. Phenotypic and genetic profiles, when examined in the context of historic literature, provide evidence that the accession in question is 'Siers' a cultivar of Carya × laneyi (an interspecific hybrid b...

An investigation on fatty acid, triacylglycerol, tocopherol, and xanthophyll contents thermal properties of pecan (Carya illinoinensis) kernel oils from two cultivars was carried out. The main acids were oleic followed by linoleic palmitic acids. predominant triacylglycerols OOL, OOO, OLL (where O stands for oleoyl L linoleoyl). Pecan oil is a rich source tocopherols, mainly γ-tocopherol. Two x...

Pecan (Carya illinoinensis) kernels have a high phenolics content and a high antioxidant capacity compared to other nuts-traits that have attracted great interest of late. Changes in the total phenolic content (TPC), condensed tannins (CT), total flavonoid content (TFC), five individual phenolics, and antioxidant capacity of five pecan cultivars were investigated during the process of kernel ri...

Thepecanweevil,Curculio caryae (Horn), and its primaryhost, pecan,Carya illinoinensis (Wagenheim) K. Kochare indigenous to North America east of the Rocky Mountains. This review is presented to describe the biology, life stages, crop injury, monitoring approaches, and primary control strategies currently used for pecan weevil in pecan. Suggested economic thresholds are extrapolated from several...

this study was conducted to determine the best pollinizer for five selected pecan cultivars in southwest of iran at safiabad agricultural research center in 2014-2015. the cultivars included: 'gratex', '10j', 'wichita 6j', 'graking', 'choctaw' as pollinated cultivars (♀) and 'gratex', 'peruque', 'comanche 4m', &apos...

The nature of the interaction between the black pecan aphid, Melanocallis caryaefoliae (Davis) (Hemiptera: Aphididae), and the chlorosis it causes to foliage of its pecan [Carya illinoinensis (Wangenh.) K. Koch)] host is poorly understood. Laboratory experiments were conducted on the settling behavior of the black pecan aphid, when provided chlorotic pecan leaf discs resulting from previous bla...

Three species of aphids attack pecan foliage, Carya illinoensis (Wang.) K. Koch, and cause economic damage. We tested a kaolin-based particle film against one of these aphid species, black pecan aphid, Melanocallis caryaefoliae (Davis). Effect of particle film on host selection, adult mortality, and production of nymphs by M. caryaefoliae was tested on seedling pecans in the laboratory. Fewer M...

Vegetation control with herbicides is a common practice in pecan [Carya illinoinensis (Wangenh.) K. Koch] orchards that benefits both non-bearing and bearing trees. However, the appropriate size for the vegetation-free area surrounding bearing trees had not been resolved. Vegetation-free circles centered on the Tree 0, 0.9, 1.8, 3.7, and 7.3m in diameter were established at planting and tree pe...

Meloidogyne partityla is a parasite of pecan and walnut. Our objective was to determine interactions between the entomopathogenic nematode-bacterium complex and M. partityla. Specifically, we investigated suppressive effects of Steinernema feltiae (strain SN) and S. riobrave (strain 7-12) applied as infective juveniles and in infected host insects, as well as application of S. feltiae's bacteri...
