HELLO;
I hope that you are fine and me am fine too.
Human being have different hormones which enable him or her self in different ways, for example adrenaline hormone help you to prepare you are body in dangerous condition.
Simirally plants have different hormones which regulate their growth. Plants hormones are also known as phytohormones or plant growth regulators.
Plant hormones are signal molecules produced within the plants and usually occurs in extremely low concentrations, they regulate cellular processes in targeted cells within the plant.
CHARACTERISTICS OF PLANT HORMONES.
1.Plant hormones are chemicals that are required in small amounts to promote and influence growth, development and differentiation of plant cells and tissues. They are active even at very low concentrations.
2.They are produced in certain parts of the plant and transported to other part of the plant where they elicit specific biochemical, physiological or morphological responses.
3.They are transported within the plant by four different types of movement namely; localized movement, cytoplasmic streaming, slow diffusion of ions and through vascular tissues, xylem and phloem.
Today I would like to share with you about one of the important plant hormone called Auxins.
Auxin are chemical compounds produced in the root and shoot apices of the plants. One of their common forms is Indoleacetic acid. Auxins play different roles in the plant, they influence cell enlargement, bud formation and root intiation, they facillitate production of phototropic response, auxins together with cytokinins control the growth of stem, roots and fruits.
They also affect cell elongation by altering cell wall plasticity and they regulate specific protein synthesis in seeds as they develop within the flower after pollination. they stimulate development of fruits without fertilisation .
There are application of synthetic of auxin in crop production such as promote rooting in cuttings, weed killers and prevent sprouting in potatoes.
SAVE PLANTS TO SAVE LIFE.
