Plant growth regulators (also called plant hormones) ... Ethylene: Ethylene is a simple gaseous hydrocarbon with the chemical structure H2C=CH2. Ethylene is apparently not required for normal vegetative growth. However, it can have a significant impact on development of root and shoots. Usually, ethylene is not used in plant tissue culture.

Ethylene, a gaseous hormone, is well known for its role in promoting fruit ripening. In addition, it plays a major role in leaf, flower, and fruit abscission. Ethylene also affects cell growth, shape, expansion, and differentiation. Plants under biotic or abiotic stresses produce high levels of ethylene which triggers an array of responses.

Plant Growth Regulators: Type # 4. Ethylene: This is a simple gaseous PGR. It is synthesised in large amounts by tissues undergoing senescence and ripening of fruits. Ethylene influences of plants include horizontal growth of seedlings, swelling of the axis, tighter apical look formation in dicot seedlings.

growth regulators often act by modifying the action of the natural hormones. For example, naphthyl phthalamic acid (NPA), a synthetic plant growth regulator and herbicide, acts by inhibiting movement of auxin.

Ethephon, an ethylene-realising compound, can induce leaf senescence as well as generation of reactive oxygen species, which in turn leads to cell death (Chen et al., 2010).

Plant Hormones: Describing the Big 5 - Untamed Science

Auxin itself wasn't discovered until the late 1920s, and it was the first of the 5 major types of plant hormones to be studied. Auxin has lots of jobs but most importantly it stimulates growth, and if a plant doesn't naturally produce auxin itself, it will die. So you can see auxin is pretty important.

Oct 27, 2017 · Have you ever tried putting an unripe pear in a paper bag with a ripe banana to ripen the pear more quickly? Go ahead! It works. The reason this works is because many ripe fruits give off ethylene, a gaseous growth hormone, when they are ripe, and ethylene triggers the generation of more ethylene, in a cascading, snowball effect within these 'climacteric' fruits.
