Guttation is the exudation of water from the surface of leaves in the form of drops and unlike transpiration it usually occurs at night. Furthermore, guttation takes through the special openings known as hydathodes which are present at the margins of leaves.

I don't think that flowers of any plant including strawberry show guttation.

You are right. However, I found young flower of strawberry show guttation.

I have never see guttation in flowers of strawberries.

Dear Prosanta

Guttation is the appearance of drops of xylem sap on the tips or edges of leaves of some vascular plants. Guttation is not to be confused with dew, which condenses from the atmosphere onto the plant surface. At night, transpiration usually does not occur because most plants have their stomata closed. When there is a high soil moisture level, water will enter plant roots, because the water potential of the roots is lower than in the soil solution. The water will accumulate in the plant, creating a slight root pressure. The root pressure forces some water to exude through special leaf tip or edge structures, hydathodes, forming drops. Root pressure provides the impetus for this flow, rather than transpirational pull.

Guttation is the process of secretion of water droplets from the pores of some vascular plants like grass. Guttation is often confused with dew droplets that condense from the atmosphere on to the plants surface. The liquid of guttation comprises a variety of inorganic and organic compounds which mainly include potassium and sugars. A white crust remains on the leaf surface.

Under the condition, where the soil is flooded with rainwater and humidity is high in the atmosphere, the plant’s root system absorbs excess water. As a result, hydrostatic pressure develops in the roots that forces water upwards. Hence the water involving other soluble cell components is forced out of the xylem present in the Epithem tissue. As a result, stomata which are filled with water is forced out by the root pressure. The liquid is forced out of the pores where the stomata offer no resistance. Transfer cells can also help in the retrieval of minerals from xylem elements and secrete it out along with water.
