Schedorhinotermes termites use hydrophilic surfaces on body and wings to attach themselves to plants they colonize. A hydrophile is a molecule or other molecular entity that is attracted to water molecules and tends to be dissolved by water. [1] In contrast, hydrophobes are not attracted to water and may seem to be repelled by it.
Vallisneria spiralis is an example of hydrophily. Female flowers reach the water's surface temporarily to ensure pollination. Hydrophily is a fairly uncommon form of pollination whereby pollen is distributed by the flow of waters, particularly in rivers and streams.
The flower of Nymphaea alba, a species of water lily Bud of Nelumbo nucifera, an aquatic plant. Aquatic plants also referred to as hydrophytes [ 1 ] are vascular plants and non-vascular plants [ 2 ] that have adapted to live in aquatic environments ( saltwater or freshwater ).
The plant hormone ethylene is a combatant for salinity in most plants. Ethylene is known for regulating plant growth and development and adapted to stress conditions through a complex signal transduction pathway. Central membrane proteins in plants, such as ETO2, ERS1 and EIN2, are used for ethylene signaling in many plant growth processes.
The higher the contact angle the higher the hydrophobicity of a surface. Surfaces with a contact angle < 90° are referred to as hydrophilic and those with an angle >90° as hydrophobic. Some plants show contact angles up to 160° and are called ultrahydrophobic, meaning that only 2–3% of the surface of a droplet (of typical size) is in contact.
Can be toxic to some plants below 10 ppm. [70] Sometimes used to produce flower pigments (e.g. by Hydrangeas). Silicon: Variable micronutrient: SiO 2− 3: 0: 140 [71] K 2 SiO 3, Na 2 SiO 3, and H 2 SiO 3: Present in most plants, abundant in cereal crops, grasses, and tree bark. Evidence that SiO 2− 3 improves plant disease resistance exists ...
Crocin is a carotenoid chemical compound that is found in the flowers of crocus and gardenia. [1] Its oxygen content also chemically makes it a xanthene. Crocin is the chemical primarily responsible for the color of saffron. Chemically, crocin is the diester formed from the disaccharide gentiobiose and the dicarboxylic acid crocetin. When ...
An essential oil extracted from the leaves and flowers is used commercially as a food flavoring and additive (geranium oil, rose geranium oil). This essential oil is classified as Generally Recognized as Safe by the US FDA when small quantities are added to foods. Pelargonium radens is used as a house plant. It is also cultivated as an ...
