Auxins and giberellins are?
Auxins and gibberellins are plant hormones involved in regulating growth and development processes. Auxins are responsible for cell elongation, root formation, and apical dominance, while gibberellins promote stem elongation, seed germination, and flowering.
How do the effects of abscisic acid differfrom those of gibberellins?
Abscisic acid inhibits seed germination, induces stomatal closure, and promotes dormancy to conserve water in plants, whereas gibberellins promote seed germination, stem elongation, and flowering by stimulating cell division and elongation. Gibberellins also counteract the effects of abscisic acid by promoting growth and development.
Where are gibberellins made?
Gibberellins are primarily synthesized in the shoot tips of plants, particularly in the young leaves and developing seeds. Once produced, gibberellins are then transported to various parts of the plant to regulate growth and development processes.
What plant hormones might be used to enhance stem elongation and fruit growth?
Auxin is a plant hormone that can be used to enhance stem elongation, while gibberellins can stimulate fruit growth. These hormones can be applied through synthetic forms or through natural sources like foliar sprays to promote desired plant growth responses.
Where do gibberellins work in a plant?
= a plant hormone/ endogenous plant growth substance hormone. they promote cell elongation of internodal regions. ie) in a dwarf plant the gene controlling gibberillins is turned off but if it is sprayed with gibberillins they will grow to normal height
A plant that produces too little of the gibberellins might?
A plant that produces too little gibberellins may exhibit stunted growth, reduced stem elongation, and delayed flowering. Gibberellins are important plant hormones that regulate various developmental processes such as germination, stem growth, and flowering.
Why do potato plants follow the sun?
I suspect that like most green plants the potato has gibberellins (growth hormones) in the stem that migrate to the side of the stem opposite the sun. On that side they stimulate stem growth, causing the stem to bend towards the sun.
Auxins and giberellins are?
Auxins and gibberellins are plant hormones involved in regulating growth and development processes. Auxins are responsible for cell elongation, root formation, and apical dominance, while gibberellins promote stem elongation, seed germination, and flowering.
How do the effects of abscisic acid differfrom those of gibberellins?
Abscisic acid inhibits seed germination, induces stomatal closure, and promotes dormancy to conserve water in plants, whereas gibberellins promote seed germination, stem elongation, and flowering by stimulating cell division and elongation. Gibberellins also counteract the effects of abscisic acid by promoting growth and development.
How is auxin different from gibberellins and ethylene in terms of function?
Auxin is involved in cell growth and elongation, while gibberellins are involved in stem elongation, seed germination, and flowering. Ethylene regulates fruit ripening, leaf abscission, and senescence in plants. Each of these plant hormones has distinct functions in growth and development.
What is gibberellins?
Gibberellins are a class of plant hormones that regulate various growth and developmental processes in plants, such as seed germination, stem elongation, and flowering. They are responsible for promoting cell division and elongation, as well as influencing fruit development and dormancy. Gibberellins are produced naturally by plants and can also be artificially synthesized for agricultural purposes.
Which hormone induce Flowering?
The hormone primarily responsible for inducing flowering in plants is gibberellin. Gibberellins promote the transition from vegetative growth to flowering by influencing various developmental processes, including stem elongation and the maturation of floral tissues. Additionally, other hormones like auxins and cytokinins can also play supportive roles in the flowering process, but gibberellins are key in triggering the flowering response.
What stimulates stem elongation seed germination and flowering?
Stem elongation, seed germination, and flowering are primarily stimulated by the plant hormones auxins, gibberellins, and cytokinins. Auxins promote cell elongation and are crucial for directional growth, while gibberellins trigger seed germination by breaking dormancy and promoting growth. Cytokinins support cell division and are involved in regulating growth processes, including flowering. Environmental factors such as light, temperature, and water availability also play significant roles in these developmental stages.
What is the effect of the amount of water or the highlight of the stem of the plant?
it affects plants by the root or stem
Both cytokinins and gibberellins promote plant growth. Compare the ways in which these hormones stimulate growth.?
Cytokinins promote cell division and growth mainly in lateral buds and roots, leading to bushier plants. Gibberellins, on the other hand, primarily promote stem elongation and leaf expansion by stimulating cell elongation. Both hormones work together to regulate various aspects of plant growth and development.
What is the function of gibberlin describe?
Gibberellins are a class of plant hormones that play a crucial role in regulating various growth processes. They promote stem elongation, seed germination, and flowering, as well as the development of fruits. By influencing cell division and elongation, gibberellins help plants adapt to their environment and optimize their growth. Additionally, they are involved in breaking dormancy in seeds and buds, facilitating the transition to active growth.
What has the author Edward P Lhuede written?
Edward P. Lhuede has written: 'Noise levels in Australian sawmills' 'Effect of gibrel on Azotobacter chroococcum' -- subject(s): Azotobacter, Gibberellins
