Answer 2

Plant Growth Regulators are described as small, simplistic chemicals generated naturally by plants to monitor their maturity and evolution.

Plant Growth Regulators can be of distinct synthetic components such as gasoline in the form of ethylene, terpenes in the form of gibberellic acid. They are also referred to as plant growth materials, phytohormones or plant hormones. Plant growth regulators like GA3, IBA, and IAA intensify the germination, maturity, and durability of seedlings. GA3 is utilized for the weakening of the roots coat so that the radical of the seedling can break by the seed coat.
