Case Study on Plant Growth Hormones
Identification of the Problems and their Causes
The two major problems that were identified by Dr. Sean include;
* Lack of sufficient Gibberellin
A sufficient level of gibberellin would stimulate the plant's development and growth. It would also stimulate the germination of seeds, stimulate the transitions from changes from meristem to the growth of shoots, leaves, flowers, grain development, and the interaction of environmental factors such as water, temperature, and light. Gibberellin plant hormones act as growth regulators. They have diterpenoid and tetracyclic elements. A seed has an embryo that develops into a plant when subjected to the appropriate environmental conditions to continue its life cycle. Physical factors such as water (moisture), temperature, and light help break the seed dormancy and trigger germination. The Gibberellin (GA) and abscisic acid (ABA) hormones help stimulate seed germination. GA triggers the germination of the seed, whereas ABA establishes and maintains the dormancy. GA hormone functions by increasing the growth capability of the embryo by stimulating the hydrolytic enzymes. In the seed germination process, a sufficient amount of GA is released in the seed's embryo, which helps weaken the seed cover by triggering gene expression in the modification and expansion of the cell. After the seed germination, a sufficient level of GA helps stimulate plant root and height development.
