Question

A particular plant hormone was used to increase the height of dwarf plants. Which hormone was it?

Answer 1

Plants that are genetically dwarf are born with a short stature. Using growth hormones or growth factors, these dwarf plants can be made to grow taller. Plant growth factors are chemical compounds that exist naturally in the environment. These assist plants in a variety of ways. They cause stem cell elongation, differentiation, and division, among other things. The growth hormone that causes plants to grow tall is found in the majority of the plant's actively growing portions.

Complete answer:
Gibberellins are the name of a plant hormone that was once employed to help dwarf plants grow taller.
Plants that are genetically dwarf are less in height than typical plants. Gibberellins are used by scientists to raise their height and cause more cell division, allowing for more longitudinal growth.
Gibberellins are one of the oldest plant hormone classes. These are crucial for seed dormancy to be broken and for shoot growth to begin. Gibberellin promotes cell division and lengthening. Dwarf plants grow higher as a result of this longitudinal stem growth.
Gibberellins are also found in the plant's most active growing areas, such as the shoot apex and tips. They elongate cells and cause them to divide rapidly due to their presence in apical areas. Plants grow taller lengthwise as a result of this.

Note:
Plant hormones are chemical messengers that cause needed changes in plant cells. Plant growth, flowering, stem and root elongation, fruiting, and other processes are induced by these substances. Various plant varieties are produced in plant tissue culturing technology, and various plant hormones are tested on them to see what effect they have.
Gibberellins have a role in a variety of germination processes. They help seedlings grow by inducing germination and giving nourishment. Gibberellins are created in the presence of cold. At lower temperatures, they are actively secreted and functioning.
