To further elucidate the regulation of dormancy release, we followed the natural afterripening of Virginia-type peanut (Arachis hypogaea L.) seeds from about the 5th to 40th week after harvest. Seeds were kept at low temperature (3 +/- 2 C) until just prior to testing for germination, ethylene production, and internal ethylene concentration. Germination tended to fluctuate but did not increase ...

Background and Objectives: Studies on packaged food by activated biopolymer starch films containing antimicrobial material is interesting field of food. Science This study investigates the effect of chitosan and rosemary essential oil on properties of starch films and peanut were packaged in them. Materials and Methods: In this study, composite films based on starch containing 0, 2, 4, 6 and...

Ethylene can induce abscission of leaves and other plant organs. Increased ethylene production by plant tissues can occur after invasion by microorganisms. The fungus Cercospora arachidicola Hori, attacks peanut leaflets and causes defoliation. Our objective was to determine if ethylene was involved in this defoliation. Leaves of three peanut, Arachis sp., genotypes were inoculated with C. arac...

BACKGROUND Peanut (Arachis hypogaea) is an important crop, but droughts often affect peanut production. There is a lack of genomic information available for peanut; therefore, little is known about the molecular basis of its drought stress response. RESULTS Previously, we found that peanut stomata close rapidly during water deficit and in response to abscisic acid (ABA) treatment, and many ge...

BACKGROUND To halt the increase in peanut allergy, we must determine how children become sensitized to peanut. High household peanut consumption used as an indirect marker of environmental peanut exposure is associated with the development of peanut allergy. OBJECTIVE We sought to validate a method to quantify environmental peanut exposure, to determine how peanut is transferred into the envi...

Peanut (Arachis hypogaea L.) is one of the most important crops produced worldwide. dominant crop in typical upland red soil areas China; however, phosphorus bioavailability very low, which severely affects peanut production. To improve bioavailability, substantially promotes green development production, a peanut–green manure rotation field experiment was conducted with six treatments (milkvet...

PURPOSE Clinical features of peanut allergy can range from localized to systemic reactions. Because peanut and birch pollen have cross-reactivity, peanut can lead to localized allergic reaction in Fagales pollen-sensitized oral allergy syndrome (OAS) patients without peanut sensitization per se. The purpose of this study was to discriminate true peanut food allergy from cross-reactive hypersens...

Peanut is a major oilseed crop worldwide. In the Brazilian peanut production, silvering thrips and red necked peanut worm are the most threatening pests. Resistant varieties are considered an alternative to pest control. Many wild diploid Arachis species have shown resistance to these pests, and these can be used in peanut breeding by obtaining hybrid of A and B genomes and subsequent polyploid...

Drought is a serious environmental stress limiting growth and productivity in peanut and other crops. Nutrient uptake of peanut is reduced under drought condition, which reduces yield. The objectives of this study were to investigate nutrient uptake of peanut genotypes in response to drought and to estimate the relationship between nutrient uptake and peanut yield under different water regi...
