However, in some cases, the mineral content of the guttation fluid can burn the tips of the leaves. Guttation, on the other hand, is xylem sap that is secreted from the plant itself. The reason why guttation occurs at night (as opposed to transpiration) is that transpiration depends on stomata. Guttation drops is seen on tips or margins of the leaves while dew drops are present all over the plant and even the soil. Water in the soil is absorbed by the roots of vascular plants by osmosis when the water potential in the roots is lower than the water potential in the soil. As the stomata close at night, transpiration does not occur. Related Videos. Take a small potted plant of Nasturtium and place it over a glass plate.

Guttation: Transpiration: 1: Occurs during night time. Guttation on the other hand is special-occasion process. Continuity of the Process: Guttation does not occur when the plant is under water stress (conditions of water deficiency). These guttation droplets are composed of xylem and phloem sap [15–17], and occur in a wide range of plant species [18–22] including rice , wheat , barley , rye , oats , sorghum , maize , tobacco , tomato , strawberry , cucumber and blueberry . In roses, guttation appears to be very uniform droplets of liquid on each leaf serration early in the morning.
