The growth and development of plants, from stem elongation to the ripening of fruit, is controlled by internal chemical signals called plant growth regulators, or plant hormones there are five classes of plant hormones: auxins, gibberellins, cytokinins, abscisic acid. Plant growth hormones you have already examined the effect of auxin on causing the growth of roots on treated leaf and stem cuttings small amounts of auxin hormone mixed with talcum powder stimulated roots to form on the leaf petioles of your cuttings. Bi 213 plant hormones 2010 objectives the purpose of this experiment is to demonstrate the ability of phytohormones to regulate growth and development during the life cycle of plants.

Researcher sarah robinson setting up acme in the lab credit: cris kuhlemeier, university of bern determining how various treatments and conditions affect the mechanical properties of plant cells could allow scientists to understand plant growth at the cellular level and devise ways to enhance it.
A plant growth experiment where gibberellic acid is added to pea plants and the growth is compared to non treated plants students design the experiment and write a lab report. Plant growth hormones are sometimes listed on the label other times, they are not if a hormone is made synthetically, it is called a plant growth regulator, or pgr two common pgrs seen on product labels are the auxins indole-3-butyric acid (iba) and napthaleneacetic acid (naa), which you have likely used in rooting hormone products.
Growth hormone (gh) is a hormone that is essential for normal growth and development in children it promotes proper linear bone growth from birth through puberty in both children and adults, growth hormone helps regulate the rate at which the body both produces energy from food and makes lipids, proteins, and glucose (sugar. In general, hormone and vitamin effects are similar and are difficult to distinguish in plants, and both are referred to in general as plant growth regulators plant hormones the growth and development of a plant are influenced by genetic factors, external environmental factors, and chemical hormones inside the plant.
