Record 2 2017-04-13

English

Subject field(s)
  • Plant Diseases
CONT

Boron Deficiency. A small quantity of boron is required for normal growth of most plants. For some there is not much leeway between necessary and toxic amounts; other plants require or tolerate large amounts. Deficiency symptoms vary with the crop... Beets, turnips, other root crops. Black Heart, Brown Heart. Roots have dark spots; plants are gradually stunted and dwarfed; leaves are small, variegated, twisted. The interior of the beet or turnip has a dark brown to nearly black water-soaked area, sometimes with a hollow center. The amount of borax that can be added without injury depends on type of soil and moisture content.

French

Domaine(s)
  • Maladies des plantes
CONT

Le manque de bore cause la maladie du «cœur brun» ou «pourriture du cœur» de la betterave. Les feuilles du cœur se développent mal, brunissent et meurent. Une déficience grave se marque par un noircissement subséquent du tissu intérieur, sous la couronne des feuilles. Une vacuole noire se forme, progressant vers l'intérieur de la racine. Parfois, de petites feuilles déformées se développent sur les bords de la vacuole. Lutte : l'application de borax, à raison de 20 à 25 kg/ha, doit être effectuée avant semis ou après la levée.

Record 3 2017-04-13

English

Subject field(s)
  • Plant Diseases
  • Root and Tuber Crops
DEF

A nonparasitic condition of the potato tuber characterized by an internal split or cavity or a central cavity lined with dark brown dead cells. It results from rapid growth induced by abundance of moisture and plant food.

CONT

Potato Hollow Heart.... Hollow heart is when potatoes have a hollow, rotten space in the center. It's caused by fluctuating moisture levels as the tubers develop.

CONT

Mineral imbalances associated with physiological disorders in crops are being studied, e. g., hollow heart in potato and cauliflower, black speck on cabbage, blotchy ripening in tomato.

OBS

Cœur creux : Affection physiologique liée aux alternances de périodes sèches et humides. Cette anomalie se traduit d'abord par l'apparition d'une tache brun clair au centre de la pomme de terre.

Spanish

Campo(s) temático(s)
  • Enfermedades de las plantas
  • Cultivo de raíces y tubérculos
CONT

Corazón hueco. El desarrollo de cavidades en el interior del tubérculo puede ser muy pequeño u ocupar toda el área de la pulpa, asimismo, es posible encontrar uno o varios "huecos" en cualquier parte del tubérculo. En la pared de la cavidad, ocasionalmente se puede formar una capa suberizada, parecida a la piel del tubérculo. El corazón hueco está asociado con periodos de rápido crecimiento del tubérculo y deficiencia de potasio. Las temperaturas frescas del suelo durante el inicio de la formación del tubérculo producen en la pulpa del tubérculo un centro café.

OBS

Cavidad corchosa en el centro del tubérculo.

Record 5 2010-03-02

English

Subject field(s)
  • Plastics Manufacturing
  • Medical and Surgical Equipment
DEF

A cast which is produced by injecting a hollow organ with plastic, allowing it to polymerize and then corroding the surrounding tissue, and which is used to prepare specimens for scanning electron microscopes. [Source: Cell and Tissue Research, 1984.]

CONT

Table I shows some example measurement made from corrosion casts from rat heart and hamster lung under several different conditions..... While the primary application of vascular corrosion casting has been and likely will remain in the elucidation of the 3-dimensional distribution of vessels in tissue and organs, high quality casts also yield valuable quantitative information about that vasculature.... the corrosion casting method [can] be used to describe or measure the internal volume of any hollow or porous structure or material as long as methods are available to remove the surrounding material and leave the cast intact.

CONT

Kidney glomerulus corrosion cast scanned with confocal microscope.

OBS

Incorporation of marker substances in the casting resin (e.g. isotopes, heavy metals, electron dense materials, photosensitive materials, or fluorescent substances) to enhance quantitative measurements are also being considered in some laboratories.

French
