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 or water glands, forming drops. Root pressure provides the impetus for this flow, rat… WebSep 17, 2024 · Hydathode is a plant organ responsible for guttation in vascular plants, i.e. the release of droplets at leaf margin or surface.

WebWater can be rise upwards in the absence of roots. When the water potential of the root becomes more negative than the soil, it causes water to move by osmosis into the root from the soil that creates a positive pressure which forces sap up the xylem to wards the leaf. Then the sap will be forced from the leaf through a hydathodes called guttation. WebJun 12, 2024 · Hydathodes and guttation act harmoniously aiming the flow of water in the plant's body, protecting the mesophyll from damaging the photosynthetic process (Feild et al. 2006; Chen et al. 2014).

A hydathode is a type of pore, commonly found in angiosperms, that secretes water through pores in the epidermis or leaf margin, typically at the tip of a marginal tooth or serration. Hydathodes occur in the leaves of submerged aquatic plants such as Ranunculus fluitans as well as herbaceous plants of drier habitats such as Campanula rotundifolia. They are connected to the plant vascular system by a vascular bundle. Hydathodes are commonly seen in water lettuce, wa… Webis capable of excreting 5–300 mL of guttation fluid per night via the hydathodes under field conditions (Datta, 1994; Flood, 1919; Moore et al., 2003). Hydathode medi-ates guttation under high humidity and in the absence of transpiration at night. A few recent studies have attempted to describe hydathode morphology in some plant species.
