1. The process by which plants release water droplets from their leaves, typically at night or early morning when soil moisture is high and transpiration is low.
Usage: plural form of guttation; botanical term; commonly observed on grass blades and plant leaves

Examples

• The gardener noticed guttations on the grass blades early in the morning.
• Guttations are a sign that the plant has absorbed more water than it can transpire.
• These water droplets from guttations are often mistaken for dew by inexperienced gardeners.
• The frequency of guttations increases when soil moisture levels are very high.
• Botanists study guttations to understand plant water regulation and stress responses.
