One of the commonly used plant growth hormone in tea plantations is
Ethylene
Abscisic acid
Zeatin
Indole - 3 - acetic acid
Indole-3-acetic acid (IAA) is a naturally occurring plant hormone that plays a role in various growth and developmental processes. It is considered an auxin, which is a class of plant hormones that promote cell elongation and division. In tea plantations, IAA is commonly used as a plant growth hormone to promote the growth and development of tea plants. It can be applied to the leaves or roots of the plant to stimulate growth, increase yield, and improve the quality of the tea leaves. However, overuse of IAA can lead to negative effects on the plant, such as distorted growth and reduced yield.
