“…Samples of C. illinoinensis varieties Wichita and Western were obtained from adult trees (approx. 40 years old) using a systematic sampling procedure (Briceño-Contreras et al, 2018); two samples were taken from root and stem during each month of an annual productive year (from July 2016 to June 2017). Root and stem samples were obtained and processed after field sampling and transferred to the laboratory according to procedures published Total soluble sugar concentration was determined using the method published by Van Handel (1968).…”

“…Soluble sugars can be stored in different vegetable tissues (Davidson, 2019;Liu et al, 2018;Smith et al, 2018;Pallardy, 2008) during time periods when either their production is abundant (Briceño-Contreras et al, 2021;Magel, Eining, & Hampp, 2000), or their demand is lower than their synthesis (Pérez-Urria, 2009). It has been reported that the highest total soluble sugars (TSS) production and accumulation rate occurs prior to flowering (Briceño-Contreras et al, 2018), and these soluble sugars are used when either the plant's energetic demand overcomes the production, or the plant could be facing some stress level (Valenzuela-Núñez et al, 2019;Pérez-Urria et al, 2009). Plants can dispose of energy required for their growth, reproduction, defence against diseases, as well as to withstand adverse environmental conditions or any other type of stress (Aluko et al, 2021;Ok et al, 2021;Liu et al, 2018;Pinkard et al, 2018;Martínez-Trinidad, Plascencia-Escalante & Islas-Rodríguez, 2013).…”

“…Moreover, the soluble sugar concentration can be affected by the plant hydration level, as in sweet cherry (Vosnjak et al, 2021); on the other hand, TSS concentration in species like C. illinoinensis depends on the phenological crop stage (Valenzuela-Núñez et al, 2019). Thus, there is a lack of information regarding the dynamics of the total soluble sugar concentration in vegetable tissues, considering parameters such as variety and season of the year given that TSS concentration in plant organs depends on diverse factors (Briceño-Contreras et al, 2018).…”

The aim of the current study was to determine the monthly total soluble sugar concentration in the stem and root of the Wichita and Western walnut (Carya illinoinensis) varieties during a productive cycle in northern Mexico. Vegetable samples were obtained using a systematic sampling method, and processed by means of a spectrophotometric assay to determine the total soluble sugars (TSS) concentration in productive walnut trees. Data analysis was performed by means of a 2-way ANOVA. The results of the TSS concentration had differences throughout the months of an annual productive cycle, and were also different between the evaluated walnut varieties. The highest total soluble sugar concentration in stem and root were in the lowest temperature months, and it decreases in both tissues when the environmental temperature rises. The Wichita variety had a higher total soluble sugar concentration than the Western in every month during the productive cycle. Further research is required to assess the effect of other type of factors including environmental or agronomic over the dynamics of the total soluble sugars in productive walnut trees.

The study took as a purpose to determine the Total Carbon (TC) content in the biomass, the Starch Carbon fraction (SC) and its annual dynamics in the biomass of perennial organs (stem and root) in adult trees of two of walnut tree (Carya illinoinensis). Four adult Western and Wichita tree stem and root samples were carried out monthly for a whole year. The TC was determined with an elemental analyser and the SC has gotten based on the molecular mass of the glucose (0.40 gC/gGlucose). t-Student test was performed between varieties per organ for the comparison of TC and SC through the program SPSS 15.0 with a significance of p ≤ 0.05. The results in Western variety were 160.02 kg TC and 4.90 kg SC to 7.54 kg SC in the stem; 64.58 kg TC and 1.74 kg SC to 3.09 kg SC in the root; in Wichita variety were presented 119.72 kg TC and 4.49 kg SC to 6.83 kg SC in the stem; 45.72 kg TC and 1.35 kg SC to 2.75 kg SC in the root. The root was the organ where the greatest amount of SC was stored in relation to the stem, due this latter constitutes a transport organ. Temperature has a marked inversely proportional influence on the accumulation of SC in both varieties. Global solar radiation and solar radiation proportionally influence the accumulation of SC.

“…El muestreo realizado fue de tipo sistemático para cada una de las variedades (Western y Wichita) y de acuerdo con la metodología desarrollada por Briceño et al (2018). Se seleccionaron cuatro árboles jóvenes de manera intercalada de una edad cercana a los 30 años en el centro de la huerta (con una extensión de 4 ha) para minimizar el efecto borde.…”

El nitrógeno es uno de los elementos nutritivos más importantes para el crecimiento y desarrollo de las plantas. Este se almacena en los órganos perennes en forma de proteínas durante el otoño e invierno y se moviliza hacia los brotes durante la primavera. El presente estudio pretendió determinar qué variables ambientales tienen un efecto en el contenido de nitrógeno proteico almacenado en el tallo de nogal pecanero. Se seleccionaron cuatro árboles de cada variedad, y se extrajeron muestras de tronco mensualmente durante un ciclo anual productivo. Se realizó un análisis de regresión lineal múltiple para observar la influencia de las variables ambientales. Los resultados obtenidos sugieren que se puede predecir significativamente el contenido de nitrógeno proteico a partir de las variables temperatura, irradiación y humedad relativa.
