ROOT FEEDER [6 records]

Record 1 2026-02-11

English

Subject field(s)
  • Horticulture
  • Plant and Crop Production
CONT

When a tree seed germinates, the first(primary) root grows down in the soil in response to gravity. Secondary roots then branch off horizontally, with subsequent branching into tertiary roots, etc. Absorption of water and mineral nutrients is the function of the very fine, non-woody roots(the feeder roots). With continued growth, each root will lose its ability for absorption. These larger woody roots then function as the transport system for water and nutrients from the new feeder roots to the stem. They are also the tree's system of anchorage and a food storage area. The resulting system thus consists of several main transport roots that extend radically and horizontally from the tree base and divide into ever smaller roots, each ending in a dense mass of fine feeder roots.

CONT

Les racines des arbres et des arbustes assurent leur ancrage dans le sol, l'absorption d'eau et de minéraux, le transport de la sève et le stockage de matière nutritive. Elles peuvent être grossièrement divisées en deux grandes catégories : • les racines ligneuses qui forment la structure du système racinaire et assurent l'ancrage ainsi que le support de la plante; • les racines non ligneuses, souvent appelées «racines nourricières», «racines fines» ou «racines absorbantes», qui ont pour principale fonction d'absorber l'eau et les éléments minéraux.

El oxígeno tomado mediante las lenticelas se transporta hasta las raíces finas, en donde se excreta y forma una rizosfera oxigenada, en donde las raíces de alimentación absorben nutrientes elementales como nitratos y fosfatos.

Subject field(s)
  • Plant Diseases
CONT

Infected roots of plants with corky root rot are distinctly corky. Extensive brown lesions, often arranged in bands with lengthwise cracking of the cortex, develop on the larger roots. The tips of infected older roots are pinched off. Small feeder roots may be completely decayed. Infected plants are stunted and slow growing. Branches on mature plants may die back from the tips.

L'ennemi des plantes le plus sournois est un champignon qui provoque la maladie de la racine liégeuse. La racine liégeuse est une maladie qui s'attaque aux cultures de serre. Les premiers symptômes de la racine liégeuse sont des taches brun clair qui apparaissent sur les racines périphériques et qui peuvent avoir jusqu'à cinq millimètres de long.

Seedlings grown outdoors and pulled from the ground for transplanting.

CONT

Choose a tree with a good strong root system, that is, with a healthy main root and many fine feeder roots. Being able to see the roots is the main advantage of buying bareroot!... It's very important to keep the roots of bareroot stock moist. Soaking the roots in a bucket of water for an hour before planting is an excellent idea. After this soaking, handle the tree quickly so it doesn’t dry out, especially if it's a windy day. Any bareroot stock bought before you’ve prepared a planting area should be heeled into a moist planting medium. Sawdust works well for this because you can lift the plant out easily, with minimal damage to roots.
