Abstract:
Cytokines and Gibberellins are known as two of the five major plant phytohormones acknowledged to contain a major impact on plant growth. They regulate plant growth and respond to environmental stress conditions. Cytokines hormone plays a role in the promoting of shoot initiation, the development of plant organs, and plant cell differentiation. The roles of gibberellins include stimulation of stem elongation, germination, seed dormancy, and the maturation of fruit and flowers. The phytohormones are customized, delivery or converted, which gives plants the ability to grown and respond against stress environments. Gibberellins have recently been discovered to be one of the main hormones that respond against abiotic stress such as wind and drought. Low levels of gibberellins have controlled plant growth restriction. This allowed plants to use their resources at a more conservative level in times of cold weather and salinity increase. On the other hand, increasing gibberellins levels allows plant to respond to plant growth allowing it to escape shady conditions and reach light. However, despite the acknowledgements of those two plant hormones in relation to regulation of plant growth, environmental stress will negatively impact the
