kasvinheteenestä

Kasvinheteenestä, often translated as "plant dew" or "vegetable dew," refers to small droplets of water that can appear on the surfaces of plant leaves, stems, and flowers, particularly during the early morning hours. This phenomenon is distinct from guttation, which is the exudation of liquid from plant pores, and condensation from external humidity. Kasvinheteenestä is typically formed when the temperature of the plant surface drops below the dew point of the surrounding air, causing atmospheric moisture to condense onto the cooler plant tissue.

The presence of kasvinheteenestä can be influenced by various environmental factors. High humidity levels in the air, clear skies that allow for radiative cooling of plant surfaces, and calm wind conditions all contribute to its formation. Plants with broad, flat leaves tend to accumulate more dew than those with fine or hairy surfaces. This moisture can play a role in the hydration of the plant, especially in arid environments, though excessive amounts can sometimes promote the growth of fungal diseases. Botanists and ecologists study kasvinheteenestä to understand water dynamics in plant ecosystems and its impact on plant physiology and disease development.
