Entry: wilting point

URI: https://data.geoscience.earth/ncl/ISO11074v2015/2.1.23

water content of the soil below which the plants are not able to uptake water with their root system. Note: Permanent wilting point (PWP) is the moisture content below which a sunflower seedling cannot recover from wilt. It is generally taken to equal a suction of 1 500 kilopascals.

de Wassergehalt des Bodens, unterhalb dessen Pflanzen Wasser nicht über ihr Wurzelsystem aufnehmen können. Note: Der permanente Welkepunkt (PWP) ist der Feuchtegehalt, unterhalb dessen sich ein Sonnenblumenkeimling nicht vom Welken erholen kann. Er wird im Allgemeinen einer Saugspannung von 1 500 Kilopascal gleichgesetzt.
fr teneur en eau du sol au-dessous de laquelle les plantes ne sont plus capables de prélever de l'eau par leur système racinaire. Note: Le point de flétrissement permanent (PFP) est le taux d’humidité au-dessous duquel le flétrissement d’un plant de tournesol devient irréversible. En général, on le considère égal à une aspiration de 1 500 kilopascals.
