Root Hair Cells

Tufted rosettes of long root hairs occur in axils of young lateral roots of peanut (Arachis hypogaea L.). Analyses of serial sections of the axils of emerging lateral roots revealed multiple layers of root hair cells. The cells of the outer layer partially overlie the adjacent cells of the inner layer. When Bradyrhizobium cells with an integrated gusA gene were inoculated onto peanut roots and the roots subsequently stained with X-gluc, blue spots indicating the presence of colonies of Bradyrhizobium were observed in the axils of lateral roots. Blue spots were also observed in other areas on the root surface. Transmission electron microscopy revealed that the primary wall of the base of root hair cells has a loose construction. Upon inoculation of Bradyrhizobium, bacteria entered only between root hair cells through the middle lamella. In other areas of the root surface other than axils of lateral roots, the cells had modified walls similar to those at the base of root hair cells. However, invasion by Bradyrhizobium of the cell wall was not observed.Key words: Arachis hypogaea, gusA-marked Bradyrhizobium, cell wall, invasion, root hair cell, root nodules.

A field experiment was conducted during 2018-19 and 2019-20 to study the effect of vermicompost and foliar spray of zinc on growth, quality and productivity of groundnut (Arachis hypogaea L.) The experiment comprising of ten treatments viz., T1 (NPK), T2 (NPK +VC), T3 (NPK +VC+ Soil Zn 100%), T4 (NPK + VC+ Soil Zn 75%), T5 (NPK + foliar spray of 0.25% ZnSO4), T6 (NPK + foliar spray of 0.50% ZnSO4), T7 (NPK + foliar spray of 0.75% ZnSO4), T8 (NPK + VC + foliar spray of 0.25% ZnSO4), T9 (NPK + VC + foliar spray of 0.50% ZnSO4) and T10 (NPK + VC + foliar spray of 0.75% ZnSO4) were replicated thrice and evaluated in the randomized block design (RBD). The experimental soil was loamy sand in texture, low in N, high in available P and medium in K. Groundnut variety, RG 559-3 was tested. The results of the experiment revealed that significantly higher values of growth parameters viz., plant height and number of root nodules plant-1; yield viz., pod yield (44.3, 47.2 q ha-1) and haulm yield (54.03, 58.8 q ha-1); quality parameters viz., oil content and protein content were recorded under the treatment receiving NPK (15:60:30) +VC (5 t ha-1) + Soil Zn 100% (T3) over control (T1) while at par with the application of NPK + VC+ Soil Zn 75% (T4), NPK + VC + foliar spray of 0.25% ZnSO4 (T8), NPK + VC + foliar spray of 0.50% ZnSO4 (T9) and NPK + VC + foliar spray of 0.75% ZnSO4 (T10).

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.
