Las semillas de hortalizas hoja son más sensibles al ataque patógenos, por lo que es necesario estudiar el potencial fisiológico las misma. Para ello se evaluó la calidad fisiológica semilla acelga (Fordhook Giant), ajo porro (Large American Flag y Flag) espinaca (New Zealand Viroflay). determinó porcentaje germinación, emergencia (PE), velocidad (VE), índice (IVE), microbiota metabolitos secun...

Isolated envelope membranes of spinach chloroplasts (Spinacia oleracea L. var. Viroflay) exhibited selective permeability. Metabolites such as 3-phosphoglycerate, bicarbonate, glyoxylate, and acetate were transported rapidly; 6-phosphogluconate, glycolate, glycine, l-malate, and succinate were intermediate; whereas glucose 6-phosphate, fructose 1,6-diphosphate, and sucrose were hardly transport...

Bicarbonate uptake by isolated chloroplast envelope membranes and intact chloroplasts of spinach (Spinacia oleracea L. var. Viroflay) in darkness exhibited a similar dependency upon temperature, pH, time, and concentrations of isolated or attached envelope membranes. This similarity in uptake properties demonstrates the usefulness of the envelope membranes for the study of chloroplast permeabil...

Downy mildew is a destructive disease of spinach worldwide. There have been 10 races described since 1824, six of which have been identified in the past 10 years. Race identification is based on qualitative disease reactions on a set of diverse host differentials which include open-pollinated cultivars, contemporary hybrid cultivars, and older hybrid cultivars that are no longer produced. The d...

The present study employed white (W), blue (B: 468 nm), red (R: 629 nm) and green (G: 524 monochromatic LED lights for 26 days, from 11:00 to 18:00 (7 h per day), with a average of photosynthetic photon flux density (PPFD) 26.00 m-2 s-1 on two baby leaves spinach (Spinacia oleracea L.) cultivars (Falcon F1 Viroflay) grown in hydroponic system. Regardless the cultivar, fresh dry weights were pos...

Spinach is one of the most important green leafy vegetables (Spinacia oleracea L.). The qualitative and quantitative trait of the spinach depends on the weather conditions. Screening the foreign accession compare with Iranian ones is necessary for breeding purposes. In order to study the vegetative characteristics of 44 endemic and foreign accessions, an experiment was conducted in a r...
