(460) De-greening of Early Season Satsumas in Louisiana

Chlorophyll Formation in Greening Bean Leaves during the Early Stages.

In the evolution of the absorption spectrum of etiolated bean leaves (Phaseolus vulgaris L.) following illumination, a rapid photoconversion of 50% or more of the active protochlorophyllide at room temperature is followed by a shift of the chlorophyll(ide) absorption maximum: C(678)--> -->C(684)-->C(672 nm). Kinetic studies at 2 C and the absence of an isosbestic point provide evidence for an i...

The Importance of Early Season Phosphorus Nutrition

Phosphorus (P) fertilization is a major input in crop production on the Great Plains, as many soils lack sufficient P for effective crop production. To optimize crop nutrition, P must be available to the crop in adequate amounts early in the growing season. Phosphorus is needed from the earliest stages of crop growth, because it is important in nearly all energy-requiring processes in the plant...

Association of transpiration efficiency with N2 fixation of peanut under early season drought

Peanut is grown mostly in rainfed areas where drought is a recurring problem. Peanut genotypes with high transpiration efficiency (TE) use less water and produced yield better under drought conditions. Specific leaf area and SPAD chlorophyll meter reading are used as surrogate traits for TE. N2 fixation (NF) is also used as a surrogate trait for yield under drought. The objective of this study ...

Complications maternelles précoces de la césarienne: à propos de 460 cas dans deux hôpitaux universitaires de Yaoundé, Cameroun

Introduction: La césarienne est l'une des interventions chirurgicales courantes en obstétrique. L'objectif de cette étude était de déterminer l'incidence des complications maternelles précoces de la césarienne dans deux hôpitaux universitaires de Yaoundé. Méthodes: Il s'agissait d'une analyse descriptive d'une cohorte de 460 cas de césariennes à l'Hôpital Central de Yaoundé (HCY) et à l'Hôpital...
