The occurrence of Fusarium spp associated with pecan tree (Carya illinoinensis) diseases in Brazil has been observed in recent laboratory analyses in Rio Grande do Sul State. Thus, in this study, we i) obtained Fusarium isolates from plants with disease symptoms; ii) tested the pathogenicity of these Fusarium isolates to pecan; iii) characterized and grouped Fusarium isolates that were pathogen...

In the present study, the efficiency of phenol removal from synthetic aqueous solutions by chemically modified biochar with the use of 1M KOH or 1M FeCl3 was investigated. Initially, biochar was produced after slow pyrolysis of three different agricultural wastes, namely pistachio (Pistacia vera L.) shells, pecan (Carya illinoinensis) shells, and wood sawdust. The quality of biochar was assesse...

A comprehensive method for evaluating kernel quality was established by estimating in detail the of 27 pecan cultivars introduced into China and exploring major trait differences among different pecan. The contents crude fat, protein, soluble sugar, tannin; fatty acid composition; amino mineral element composition were analyzed tested using national standards principal component analysis (PCA),...

The existence of nickel (Ni) deficiency is becoming increasingly apparent in crops, especially for ureide-transporting woody perennials, but its physiological role is poorly understood. We evaluated the concentrations of ureides, amino acids, and organic acids in photosynthetic foliar tissue from Ni-sufficient (Ni-S) versus Ni-deficient (Ni-D) pecan (Carya illinoinensis [Wangenh.] K. Koch). Fol...

Abstract The Soil Management Assessment Framework (SMAF) is a quantitative soil quality (SQ) evaluation tool that widely applied to assess response specific agricultural management practices over time. Considering the reported SQ benefits of agroforestry (AF) systems and potential usefulness SMAF, objective this study was evaluate effects tree species (pecan [ Carya illinoinensis (Wangenh.) K. ...

The rhizosphere microbiome is closely related to forest health and productivity. However, whether soil type affects pecan (Carya illinoinensis) microbiomes unclear. We aimed explore the diversity structural characteristics of bacteria associated with plantations grown in three types (Luvisols, Cambisols, Solonchaks) Eastern China analyze their potential functions through high-throughput sequenc...

Pecans kernels (Kanza and Desirable cultivars) were irradiated with 0, 1.5, and 3.0 kGy using electron-beam (E-beam) irradiation and stored under accelerated conditions [40 degrees C and 55-60% relative humidity (RH)] for 134 days. Antioxidant capacity (AC) using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and oxygen radical absorbance capacity (ORAC) assays, phenolic (TP) and condensed tannin (CT) co...
