What do you mean by growth inhibitor?
Growth inhibitors. endogenous or exogenous substances which inhibit the normal growth of human and animal cells or micro-organisms, as distinguished from those affecting plant growth (= plant growth regulators).
What are examples of growth inhibitors?
Examples are auxins, gibberellins and cytokinins. Plant Growth Inhibitors – These chemicals inhibit growth and promote dormancy and abscission in plants. An example is an abscisic acid.
Which one is growth inhibitor?
Solution : ABA (Abscisic Acid) is a naturally occurring growth inhibitor in plants.
What’s another word for inhibitor?
What is another word for inhibitor?

What is natural growth inhibitor?
Hormones like Abscisic Acid (ABA), ethylene are growth inhibitor. These hormones accelerate abscission process and are involved in inhibition of growth.
What do you mean by growth promoters?
Growth promoters are mainly used in farm animals with the purpose to promote growth, to improve the distribution of fat and protein, and to increase the feed-to-muscle conversion rate.
What are growth retardants?
Plant growth retardants are applied in agronomic and horticultural crops to reduce unwanted longitudinal shoot growth without lowering plant productivity. Most growth retardants act by inhibiting gibberellin (GA) biosynthesis.
Why ABA is called growth inhibitors?
The stress hormone abscisic acid (ABA) induces expression of defence genes in many organs, modulates ion homeostasis and metabolism in guard cells, and inhibits germination and seedling growth.
Does inhibit mean decrease?
Definition of inhibit to prohibit; forbid. Psychology. to consciously or unconsciously suppress or restrain (psychologically or sociologically unacceptable behavior). Chemistry. to decrease the rate of action of or stop (a chemical reaction).
What are the growth regulators?
Plant growth regulators (PGRs) are chemicals used to modify plant growth such as increasing branching, suppressing shoot growth, increasing return bloom, removing excess fruit, or altering fruit maturity.
Which includes growth promoters?
So, the correct answer is ‘Auxins and cytokinins’
Which is not a growth retardant?
Abscisic acid is not a growth promoter.
Is ethylene a growth promoter or inhibitor?
Ethylene is used as both plant growth promoters and plant growth inhibitors. Ethylene is synthesized by the ripening fruits and ageing tissues.
Which is powerful growth inhibitor?
ABA is a powerful growth inhibitor.
What is difference between inhibit and prohibit?
As a general rule, it’s safe to use inhibit when you’re talking about internal motivations or an action that’s restricted or limited. It’s generally best to use prohibit when talking about pressure from an external source (like the law) or an action that’s completely prevented.
