Phenolic compounds are related to high biological activity,avoiding oxidation in food and human systems.Nutshells are by-products derived from the pecan nut processing that contain important amounts of phenols which biological activity must be studied.This research aimed to evaluate the antioxidant(DPPH,ABTS,FRAP and hemolysis)and anti-inflammatory activities of shell extracts from pecan nuts harvested during the crop production cycle 2018 and 2019,as well as the in vitro digestibility of their phenolic compounds,including flavonoids.Results showed that extracts from the crop production cycle 2018 obtained the highest yield,while those from 2019 contained the highest concentration of phenolic compounds,flavonoids and antioxidant capacity determined by DPPH(22.96 mmol ET),ABTS(91.55 mmol ET)and inhibition of hemolysis(92.12%).The anti-inflammatory activity exhibited an inhibition of the elastase enzyme up to 50 min and the bioaccessibility of phenolic compounds reached up to 32%.These results showed that pecan nutshell extracts are an important source of biologically active compounds,thus,they are suitable to be used as commodities in different fields such as agricultural,food and pharmaceutical industries.Future studies must be carried out in order to elucidate the activity of nutshell extracts within in vivo systems.

The pecan nut is considered one of the most important dried fruits in the world by its classification as healthy food. The nutritional balance in the harvest is crucial for its impact on the production, quality and content of bioactive compounds. This research was carried out in the city of Aldama, Chihuahua (Mexico), where doses of mineral and organic fertilization were tested in L25 Taguchi structure with 6 factors and 5 levels by factor: nitrogen (N) 0 - 240 kg·ha-1, phosphate (P2O5) 0 - 120 kg·ha-1, potassium (K2O) 0 - 100 kg·ha-1, calcium (CaO) 0 - 400 kg·ha-1, liquid humus 0 - 3600 L·ha-1 and solid humus 0 - 8000 kg·ha-1. An average yield of 2.2 t·ha-1 was obtained;145 nuts per kilogram, 60% of the edible part of the nut. The total phenolic content was 225.9 mg gallic acid g-1 and the antioxidant capacity was 180.9 mg Trolox g-1. It is concluded that the factor with the greatest impact on yield, quality and antioxidant capacity in pecan nut was nitrogen. It was also found that the combination of mineral and organic fertilization helps to maintain the production and quality ranges of the nut. In turn, these factors contribute to the increase in the phenolic strength and antioxidant capacity. The optimal fertilization dosis to obtain the maximum levels in production of 3.2 t·ha-1;decrease the number of nuts per kilogram to 135, increase the percentage of the edible part of the nut to 61.8%, the increase in the total phenolic content to 318.6 mg of gallic acid g-1 and in the antioxidant capacity with 187.2 mg of Trolox g-1, was 184 kg·ha-1 of N, 107.4 kg·ha-1 of P2O5, 50 kg·ha-1 of K2O y 2777 L·ha-1 of liquid humus. Finally, the mineral fertilization complemented with organic fertilization is considered a good fertilization strategy for pecan trees and its possible benefits to health and the environment.

Antibiotics are widely used in fire blight management programs,yet there are no studies that demonstrate the evaluation of their efficacy in Mexico.Therefore,the present study was conducted to investigate the effects of the active ingredients in five commercial products(Kasumin■2L,Agrygent Plus■,Agricultural Terramycin■,Agrimicin100,and Actigard■)on fire blight suppression,and fruit yield and quality of apple(Malus domestica Borkh.)cv.Golden Glory.The experiment was conducted in a commercial orchard using a completely randomized block design,with six treatments:(1)Oxytetracycline[Ox],110 mg L^(−1);(2)Kasugamycin[Kas],4.7 mL L^(−1);(3)Oxytetracycline+Gentamicin[Ox+Gen],48 mg L^(−1)+12 mg L^(−1);(4)Streptomycin+Oxytetracycline[Str+Ox],90 mg L^(−1)+9 mg L^(−1);(5)Acibenzolar-S-methyl[ASM],70 mg L^(−1);and(6)Control,only water,with four replications,and three 11-year-old trees as an experimental unit.Variables of infection including flowers,shoots and fruits,yield and fruit quality were evaluated.All treatments suppressed infection in flowers,shoots,and fruits.ASM provided the highest levels of reduction of flower and shoot infection,while Kas had the least effect on the reduction of infection in these variables.The Ox+Gen treatment had the greatest suppression of fruit infection,and the best results on fruit yield and quality,followed by Ox and ASM.This is the first study conducted to evaluate the efficacy of the active ingredients of five commercial products used for the management of fire blight in apple trees in Mexico.
