The peanut plant (Arachis hypogaea L.) produces flowers aerially, but it is able to "sow" its own seeds as a result of the growth of a specialized organ called the gynophore. The peanut gynophore is sensitive to light, touch, and gravity, and it is capable of transporting the recently fertilized ovules into the soil. For gynophore growth to occur, many physiological changes in plant hormone accumulation and distribution take place throughout its development. The unique characteristics and physiological events occurring during the gynophore's growth and development, such as its growth rates and indole-3-acetic acid redistribution during gravistimulation, will be reviewed. The peanut gynophore illustrates that the study of the odd or unusual can often provide valuable answers about the typical.Key words: Arachis hypogaea, geocarpy, gravitropism, gynophore, indole-3-acetic acid (IAA), peanut.

Abstract Two experiments were conducted to determine the contribution of leaves at different stem positions to photosynthesis of peanut plants, and the change in this contribution with plant age. Apparent photosynthesis (AP) and translocation of assimilated 14C were determined on leaves 3, 5, and 8 from the tip of a cotyledonary lateral branch of the “Florunner” cultivar of peanut (Arachis hypogaea L.) at 80, 110 and 140 days after planting. To determine 14C-photo-synthate translocation individual leaves were exposed for 15 min to 14CO2 and plants harvested 24 hr later were analyzed for 14C. Translocation was computed as the percentage of total 14C in the plant which was in plant parts other than the labeled leaf. Highest AP was observed for leaf 3, the youngest fully expanded leaf on the branch, and the lowest AP for leaf 8. Leaf 5 exhibited intermediate AP rates. AP decreased with plant age, the average decrease in two experiments being 21 and 58% from 80 to 110 and 140 days, respectively. The decline in AP with plant age was similar in both experiments. The percentage of 14C translocated from labeled leaves for the two experiments averaged 64% and was not significantly affected by plant age. A significantly greater percentage (76%) of the 14C fixed was translocated from leaf 3 in Experiment II than from leaves 5 and 8 which averaged 55%. Leaf position had no effect on 14C translocation in Experiment I. These data indicate that leaves near the periphery of the peanut plant contribute most during pod filling and that the photo-synthetic capacity of all leaves decreases during this period.

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.
