Abscisic acid, sometimes known as ABA, is an inhibitor of plant development in general. It causes the plant to go into dormancy and stops the seeds from developing; it causes the leaves, fruits, and flowers to fall off; and it causes the stomata to close up.
Which of the following plant hormone inhibits growth in leaves?
Abscisic acid is a hormone that is produced by plants and has the effect of stunting their growth. It is produced by the leaves of plants. It encourages senescence, often known as withering or the falling off of leaves. Abscisic acid has the additional effect of preventing the germination and growth of seeds.

What are hormones in plants?
Hormones are chemical compounds that are responsible for the growth and development of the plant body. They are secreted by various portions of the plant body and are responsible for the different parts of the plant body to produce them. The plant has a variety of hormones, each of which is responsible for controlling a specific function or process inside the plant itself.
What is an example of a plant growth inhibitor?
Characteristics.Auxins, gibberellins, and cytokinins are some examples of phytohormones.Inhibitors of Plant Development – These compounds cause plants to enter a state of dormancy and abscission, which inhibits their growth.One such compound is known as an abscisic acid.Note that although ethylene may act either as a promoter or an inhibitor of plant growth, it primarily acts as an inhibitor.
Which acid also inhibits seed germination and development?
Abscisic acid has the additional effect of preventing the germination and growth of seeds. Did you find that answer helpful?
