Abstract Peanuts (Arachis hypogaea L.), cultivar Florunner, from plants inoculated with peanut stripe virus (PStV) were evaluated for chemical composition in comparison with peanuts from uninoculated plants. At harvest, seed were collected from plants which had been mechanically inoculated with PStV at emergence, or 20, 40, or 60 days after emergence and from uninoculated plants. The seed from PStV-infected plants had increases in manganese, selenium, zinc, iron, tartaric acid, raffinose, glucose, fructose, and total carbohydrate contents as compared to seed from uninoculated plants. Sucrose was increased in seed from plants inoculated with PStV at time of emergence. There was a decrease in the concentration of potassium, magnesium, protein, and total soluble phenolics of seed from plants inoculated with PStV. There were no changes in the concentration of stachyose, inositol, phosphorus, sulfur, calcium, copper, and oil.

Abstract Most peanut (Arachis hypogaea L.) fields of the Southern Coastal Plain are treated with either vernolate (S-propyl dipropylthiocarbamate) or benefin (N-butyl-N-ethyl-a,a,a-trifluoro-2, 6-dinitro-p-toluidine) or a combination of these two herbicides to control certain weeds. The nematicide DBCP (1,2-dibromo-3-chloropropane) is also used in some fields. Field and greenhouse experiments were conducted to determine the effect of vernolate, benefin, DBCP, and Rhizobium sp. on nodulation, yield, quality, and chemical composition of ‘Starr’ peanuts. The application of herbicides, nematicide, and inoculant had no significant effect on yield, sound mature kernels, or ether extract of ‘Starr’ peanuts. The N content of the leaf and seed and the number of nodules were not affected by the treatments. Nematode infestation was low and did not affect yield. In the greenhouse studies, the application of lime, herbicides, or fertilizer did not affect certain morphological characteristics of the plant or N content of the peanut leaves. Nitrogen fertilization increased the weight of the peanut foliage.

Objetivo: Evaluar la germinación de cacahuate (Arachis hypogaea L.) mediante el uso de diferentes dosis de ácido giberélico (GA3). Diseño/metodología/aproximación: Se empleó un diseño completamente al azar. Se utilizaron tres tratamientos con 20 repeticiones. Tratamiento 1: 0.05gr/L de ácido giberélico (GA3), Tratamiento 2: 0.10gr/L de ácido giberélico (GA3), Tratamiento 3: 0.15gr/L de ácido giberélico (GA3) y Tratamiento 0: Testigo. Se utilizaron semillas de cacahuate de la variedad Virginia. Los parámetros a evaluar fueron, la altura de plántula, número de hojas, medida de raíz y biomasa.  Las medias fueron comparadas por la prueba de Tukey a un nivel del 5% de confianza. Resultados: Los tratamientos indicaron que el Tratamiento 0 (Testigo) obtuvo un porcentaje de germinación de 85%, siendo mayor que el tratamiento 3 (0.15gr/L de GA3) con un 75% de germinación, sin embargo, el tratamiento 1 (0.05gr/L de GA3) y 2 (0.10gr/L de GA3) presentaron una mejor respuesta al obtener un 95% de germinación cada uno. Limitaciones del estudio/implicaciones: El tratamiento 3 causa efectos negativos en la germinación de la planta. Hallazgos/conclusiones: Es necesario dar seguimiento a la investigación para un mejor control del ambiente y ampliar las dosis de GA3, así como aumentar la velocidad de germinación aplicando 0.15gr/L de GA3.
