Plant Growth Hormones - The Key Players In The Process Of Seed Germination
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 3
Abstract
Plant growth hormones along with numeral factors are the key players in the process of seed germination and seedling growth. They are produced by both plants and soil bacteria. They are defined as organic compounds other than nutrients, that affects the physiological processes of growth and development in plants when applied in low concentrations. Plant hormones and plant gene interactions also affect seed germination. Hormones activity of plants is controlled by expression of genes at different levels as plant genes are activated in the presence of specific plant hormones. So, seed germination can be enhanced be adjusting gene expression at different levels. The process of seed germination and the establishment of the seedling, the role of soil bacteria are quite significant for the production of plant hormones. The chief important plant hormones which influence germination process are abscisic acid, ethylene, gibberellins, auxin and cytokinins. They are biochemical substances which reins numerous bio-chemical and physiological processes in the plant.
