DEF

The ability of plants to either postpone dehydration or tolerate dehydration during a period of drought such that damage is prevented, reduced, or repaired.

CONT

Most species of plants can survive short dry periods without serious injury, but a prolonged period of soil water deficiency is highly injurious or lethal to all except those species of plants with a well-developed capacity for drought resistance ... A fundamental factor in the drought resistance of plants therefore appears to be a capacity of the cells to endure a substantial reduction in their water content without suffering injury.

OBS

Drought tolerance is often assessed relative to the plant's natural environment or when plants are placed together in the same environment.

DEF

Capacité d'une plante à retarder la déshydratation ou à la tolérer pendant une période de sécheresse, qui lui permet d'empêcher ou de réduire les dommages qui en découlent ou d'y remédier.

CONT

Ainsi, une diminution progressive de l'arrosage semble propice pour certaines essences, de même qu'une ventilation plus forte aurait un effet bénéfique sur la tolérance à la sécheresse.

OBS

On écrirait mieux «sècheresse».

sècheresse : Cette graphie, puisée des Rectifications de l'orthographe recommandées par le Conseil supérieur de la langue française, est attestée dans le Petit Robert (2006).
