Resumen

In this work, the influence of the bioregulators gibberellic acid, calcium prohexadione and thidiazuron on nutrition, soluble carbohydrates and yield components to mitigate alternation in pecan walnut varieties Western Schley and Wichita was analysed. The experiment was conducted at the Nogalera "Loma Bonita" commercial orchard, located in Sacramento, Chihuahua, during 2017-2018. Treatments were applied at 0, 56, 70 and 84 days after full flowering (DDPF). Working with vegetable leaves in the Chemistry laboratory of the Faculty of Agrotechnical Sciences. Using a completely randomised design, with four treatments: three bioregulators and a control, with six replicates, according to the results, a general linear model was used with the effects of year, variety and treatment with their interactions of two and three effects, the data were analysed in the statistical programme SAS software, ver 9.3, complying with the Shapiro-Wilk Normality. The results indicate that there is a significant difference in the foliar application of bioregulators: GA3, PCa and TDZ, influenced the nutrients Zn, Nt and P, soluble carbohydrates: sucrose and starch, and yield components: kernel percentage, grams per nut, in pecan nut for both varieties from one cycle to another.
