Why auxin and cytokinin ratio is more important for callus culture?
The ratio of auxin to cytokinin is crucial in callus culture because it directly influences cell division and differentiation. A higher ratio of cytokinin promotes shoot formation, while a higher ratio of auxin favors root formation. Balancing these hormones is essential for generating healthy and productive callus cultures.
What hormone causes plants to grow toward light?
Auxin is a chemical which makes plants grow faster.Specifically, the chemical in question can be described as a plant hormone or phytohormone to regulate growth. The terms comes from the Greek word αυξειν (auxein) for "to grow, to increase." Auxin may occur naturally -- often in cooperation with the plant hormone cytokinin -- or synthetically.
What are the 4 hormones used in horticulture?
The 4 hormones commonly used in horticulture are auxins, cytokinins, gibberellins, and abscisic acid. These hormones play key roles in plant growth and development, including cell division, shoot elongation, fruit development, and stress responses. By manipulating the levels of these hormones, horticulturists can control various aspects of plant growth and physiology.
Morphogenesis in plants results from what?
Morphogenesis in plants results from the coordination of cell division, elongation, and differentiation. Hormones such as auxin and cytokinin play a key role in regulating these processes, along with environmental factors like light and temperature. The unique cell walls of plant cells also contribute to the overall shape and structure of the plant.
How plant hormones help create seedless fruit?
Plant hormones can stimulate the development of fruit without seeds through a process called parthenocarpy. By manipulating the balance of hormones such as auxin, cytokinin, and gibberellins, seedless fruits can be produced. This can be achieved naturally or through genetic modification techniques.
What are the five plants?
Auxin,Cytokinin,Abscic Acids,Gibberellin,&Ethylene

What media is recommended for tissue culture of alstonia scholaris?
For the tissue culture/callus culture of Alstonia scholaris MS media supplemented with a balanced concentrations of 2,4-D(auxin) and FAP(cytokinin) can be used.The concentrations of auxin/cytokinin are*****mg/l [(kumarsumit90@gmail.com :) ;)]
What is thidiazuron?
It is plant growth regulator. it is a cytokinin. Cytokinin is involved in both local and long distance signalling; as a long distance signal CK shares the same transport systems used by the plant for moving purines and nucleosides. Cytokinins are involved in many plant processes, including cell division, shoot and root morphogenesis, chloroplast maturation, cell enlargement, auxiliary bud release and senescence. The ratio of auxin to cytokinin is crucial during cell division and the differentiation of plant tissues and auxin is known to regulate the biosynthesis of cytokinin
Are plant hormones an example of an internal stimuli?
Yes many plant hormones are secreted by plants internally. Such as auxin, gibbrailin, cytokinin etc.

Is giberellin a misspelling of gibberellin Gibberellin has an answers.com entry while giberellin only has a 'Food and Nutrition' entry.?
Gibberellin is a hormone that regulates growth. Its effects are typically seen in plant stem elongation.
Is Cytokinin poisonous?
i have never used Cytokinin, like other orchid growers i am looking at any way to improve my plants
Crop physiological role of cytokinin?
Cytokinin are made in greatest amounts in the roots. Simply put, they may be an indication that things are going well for the root and shoot growth may therefore commence. The principle roles of the root are to take in water and minerals from the soil, to anchor the plant and to store nutrients like starch that has been made by the leaves (the last in some but not all plants). Since it's possible that salicylic acid acting as a hormone may be an indicator of an abundance of water, cytokinin may indicate that the plant is taking in more than enough minerals from the soil to just survive, so that it is OK to start growing more stems and leaves. In fact cytokinin inhibits senescence of leaves, and promotes new stem growth. Whether it needs a high level of salicylic acid also as indicator to give the green light to stem growth, is a good question... It's also quit probable that even if the plant is taking in good amounts of water and minerals from the roots they would not make salicylic acid and cytokinin if the root were under duress for other reasons, say by infestation, flooding or dislodging. In other words any condition that plant is in where it might be good to wait to start growth until a better situation is achieved. It's possible cytokinin is still made under these circumstances but the minerals are instead store for a better day. One last possibility is cytokinin alone indicates root prospering just as perhaps auxin alone indicates stem prospering. The reason for saying this is that cloning a single isolated plant cell into a full new plant, seems to require only cytokinin and auxin, not the additional salicylic and jasmonic acid (jasmonate is proposed in this present author's scheme as a sugar indicator with Auxin relegated to a role as a carbon dioxide and oxygen uptake indicator). Mind you most scientist woulds consider this entire answer highly speculative.
Is gibberellin a plant growth hormone?
true
What plant hormone causes to grow rapidly?
Gibberellin
