What Is Cytokinin? (And How It Affects Your Plants)


Cytokinin, also known as auxinic acid, is a plant hormone that is involved in the process of flowering. Learn more about Cytokinin’s function and how it affects plant life by reading this article!


What is Cytokinin?


Cytokinin is a plant growth hormone that stimulates and controls plant growth, specifically root development. It stimulates the production of auxin in plants and helps to promote average, healthy growth. Cytokinin is a type of plant growth hormone and is initiated by girdling roots. Girdling refers to removing tissue from the roots preventing the flow of water and nutrients to the rest of the plant. This treatment promotes root growth, which stimulates more outstanding Cytokinin production. In combination with other hormones, Cytokinin was initially used as a pest-control measure against Japanese beetles on citrus trees.


What is Lint Exposure? Lint Exposure refers to the accumulation of dust, lint, and pet hair on patients’ tracheas. If left untreated, lint exposure can cause respiratory problems, including but not limited to pneumonia. What are the Symptoms? Lint exposure symptoms vary in severity depending on how long it has been present and whether or not any damage has occurred to the trachea. Some patients may experience discharge from their nose, which can potentially turn into an infected condition known as Sinusitis. Patients with this symptom may also have a decreased response to oxygen therapy.


How is Lint Exposure treated? If a patient is diagnosed with lint exposure, treatment will consist of managing their symptoms and the condition of their trachea until it heals. Several different methods can be used to help treat this condition.


How does Cytokinin work?


Cytokinin is a plant hormone that controls the development of plant organs, such as leaves and fruit. Cytokinin also makes plants more resistant to environmental stressors like cold, drought, and high temperature. The proper levels of Cytokinin in the leaves play an essential role in plant development and growth, especially when plants experience a period of drought.


Cytokinins are produced naturally by many plants during total daylight hours, with the highest levels being produced by seedlings and newly developing leaves. Cytokinin production declines as the season progresses and increases at night when the day’s length is shorter. For this reason, producers often tend to increase cytokinin production when they begin harvesting their crops at the end of summer, producing a spike in cytokinins during crop development. Cytokinins are not produced in high concentrations all year long but rather increase and decrease with the seasons. Cytokinin production is a function of several factors, including day length, temperature, relative humidity, and photoperiod length. Each of these factors can significantly affect the amount of Cytokinin produced in a given period. The most crucial factor is day length. Under short photoperiods, such as during winter months or when it is cloudy during harvesting, there may be no fall cytokinin peak at all because the plants cannot produce enough cytokinins to reach the fields in time. Therefore, it is essential to determine the time of year that production will occur and plan accordingly.


What Does Cytokinin Do?


Cytokinin is a hormone that stimulates the production of chlorophyll in plants. The plant produces it to help bloom and fruit during the summer season. In winter, it can be used as an internal cue for a plant to stop producing chlorophyll and start resting in preparation for springtime. Cytokinin is also known as auxins, plant hormones that regulate growth and development. All plants naturally produce this hormone. A critical function of Cytokinin is to signal the stem cells to divide accordingly to help maintain the size of a plant throughout its life cycle, from seedling through maturity.


How Does Cytokinin Work?


Cytokinins work by signaling the stem cells to divide and increase for the plant to survive. In this way, the stem cells proliferate and grow taller, thus allowing the plant to produce more chlorophyll and food. Cytokinins are also known as auxins, and all plants naturally produce them. This works by signaling the stem cells to produce chlorophyll and food for the plant to survive. The production of Cytokinin is controlled by light intensity or temperature. The light intensity that triggers cytokinin production is not necessarily in direct proportion to the sunlight that reaches the plant. The temperature of the plant also plays a role in triggering cytokinin production. In general, if there is an increase in temperature or nighttime temperatures are more relaxed than daytime ones, then cytokinin production will be triggered. Cytokinins work by signaling the stem cells to divide and increase for the plant to survive.


Plant Diseases Involving Cytokinin


Cytokinin is also known as a plant growth hormone. It affects how plants grow and survive. Plants in a darker location need more Cytokinin to grow because there’s less sunlight for them. Darker plants tend to be slower growing, so it helps them to compete for resources against other plants. Cytokinin also plays a role in how plants are affected by pesticides. In general, plants exposed to highly toxic chemicals tend to exhibit less cytokinin production than plants that aren’t exposed to the same chemical. Finally, when using some types of insecticides and fungicides on plants, such as the organophosphate pesticides, there’s been a link made in studies to decreased cytokinin levels among plants.


Plant Diseases Involving Ethylene. Ethylene gas is produced naturally in the plant as part of metabolizing carbohydrates. It also is an important signal that plays a role in keeping plants healthy and disease-free. Ethylene is involved in many plant diseases, especially potatoes and tomatoes. When other plants are exposed to ethylene gas, they tend to become more sensitive to infections by various fungi or bacteria. Again, this results in less vitality and malnourishment among plants under such conditions. Other diseases that have been linked to elevated levels of ethylene gas include the following:6—altered sugar metabolism. When ethylene gas is present in excess, it can act as a stimulator of sugar metabolism. This results in plants having an enlarged root system, making them more susceptible to fungal infections and diseases.7—poor nutrient absorption.




In conclusion, Cytokinin is an important hormone that regulates growth and development in plants. This hormone is produced in the plant leaves and seeds, and it controls how plants receive nutrients from the soil. It also decreases the amount of water and nutrients in the soil by causing plants to produce their own.


Cytokinin is not just a hormone for plants; its compounds can also be found in animal tissues. A couple of Cytokinin’s uses are being used for food preservation, such as making foods last longer giving the cheese its flavor. Cytokinins have also been used in treating cancerous cells and are found in many other natural remedies like garlic.
