Karrikins – effect on plants, interaction with other growth regulators, and potential use in horticulture

Karrikins are a group of chemicals found in plant-derived smoke from burning plant material. Till now, scientists concentrated on their effect seed germination plants sensitive to smoke. However, there reports the karrikins physiology and morphology which do not occur fire areas naturally treated by These positively affect biometric parameters vitro cultured plants. Recently, rate pollen several species has been confirmed. They interact with growth regulators enhancing effects, for example using them together auxins, cytokinins, gibberellins, abscisic acid or ethylene. This paper contains review present research proposes perspectives further investigations, as well application these horticultural production new regulators.
