what is plant growth retardants definition
The most common growth regulators used in greenhouse crop production are the plant growth retardants. Quality standards dictate that most container-grown greenhouse crops be compact, have short internodes, have a height consistent with the container they are grown in and have strong stems.rowth regulators may also be used to slow growth or hold plant material in the greenhouse. The growth retardants function by inhibiting gibberellin synthesis. If gibberellins are applied to a plant, it will become tall and spindly.
