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...

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...

Ceratocystis fimbriata is a widely distributed, plant pathogenic fungus that causes wilts and cankers on many woody hosts. Earlier phylogenetic analyses of DNA sequences revealed three geographic clades within the C. fimbriata complex that are centered respectively in North America, Latin America and Asia. This study looked for cryptic species within the North American clade. The internal trans...

Genetic relationships were studied among eight species of three taxa in the genus Chaenomeles by nuclear ribosomal internal transcribed spacer (ITS) analysis. A genetic distance matrix based on ITS sequences was estimated according to the formula of Kimura-2 parameter and a neighbour-joining phenogram, which were obtained with Clustalx4.1 software. The results showed that the germplasms of Mugu...

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...

The objective of this study was to characterize species of the Cladosporium cladosporioides complex isolated from pecan trees (Carya illinoinensis) with symptoms of leaf spot, based on morphological and molecular approaches. Morphological attributes were assessed using monosporic cultures on potato dextrose agar medium, which were examined for mycelial growth, sporulation, color, and conidia an...
