Ethylene has been shown to hasten the aging and death of plant parts, particularly the flowers and leaves of the plant. In the process of ripening fruit, ethylene is quite efficient. During the process of ripening, it speeds up the pace at which the fruits breathe. The term ″respiratory climactic″ refers to this increase in the pace at which one breathes.
Ethylene is a gaseous plant growth regulator that speeds up the pace at which plants breathe when their fruits are ripening. It does this by stimulating the production of ethylene. It is referred to as respiratory climactic when there is an increase in the rate of respiration. Therefore, the answer that you are looking for is ″Ethylene.″
What are plant growth regulators and plant growth hormones?
Plant growth regulators as well as hormones that stimulate plant growth.It plays a part in some stages of plant growth, such as the ripening of unripe fruits and other similar processes.As a result, they play a role in the development of the plant to some extent.Ethylene: Ethylene is a phytohormone that exists in gaseous form.Similar to absicic acid, it has a growth-inhibiting effect.Its primary function is to aid in the maturity and ripening of fruit.
What are some examples of plant growth regulators and inhibitors?
Auxins, gibberellins, and cytokinins are some examples of plant hormones.Inhibitors of Plant Development – These compounds cause plants to enter a state of dormancy and abscission, which inhibits their growth.One such compound is known as an abscisic acid.Note that although ethylene may act either as a promoter or an inhibitor of plant growth, it primarily acts as an inhibitor.Unintentional discovery led to the discovery of all plant growth regulators.
How are phytohormones involved in the growth of plants?
It plays a part in some stages of plant growth, such as the ripening of unripe fruits and other similar processes.As a consequence, they have a role, although a limited one, in the expansion of plant life.Ethylene: Ethylene is a phytohormone that exists in gaseous form.It has the same growth-inhibiting properties as abscisic acid.Its primary function is to aid in the maturity and ripening of fruit.
Which of the following are plant growth promoters?
Plant Growth Promoters are substances that encourage the division and growth of plant cells, as well as blooming, fruiting, and the development of seeds. Auxins, gibberellins, and cytokinins are some examples of phytohormones.
Which plant hormone is involved in respiratory climatic effect?
There is a correlation between ethylene and respiratory climate.
What causes climactic respiration?
During the process of ripening, ethylene speeds up the rate of respiration that occurs in the fruit. The term ″respiratory climactic″ refers to the increase in the rate of breathing that occurs during this phase.
What is ethephon used for?
Ethephon is a plant growth regulator that is used to stimulate the ripening of fruit, abscission, and the induction of flowering, amongst other reactions. Cotton is the primary crop for which ethephon is utilized, despite the fact that it is registered for use on a wide variety of food, feed, and nonfood crops, greenhouse nursery stock, and outdoor residential decorative plants.
What are the 5 major plant growth regulators?
At this time, there are five distinct classes of plant hormones that have been identified: auxins, gibberellins, cytokinins, abscisic acid (ABA), and ethylene. Together, they are responsible for the coordination of the expansion and maturation of cells.
What is respiratory climacteric?
1. An increase in the rate of respiration that occurs at an exponentially increasing pace as the fruit ripens. Thermal Technologies and Systems for Food Preservation is where you can learn more about this topic.
What is the role of ethylene in plant growth?
It is believed that ethylene acts as a multifunctional phytohormone that controls senescence in addition to growth in plants. Depending on its concentration, when it is applied, and the kind of plant it is applied to, it can either encourage or discourage the processes of growth and senescence.
What is climacteric in plants?
The climacteric stage of fruit ripening is the ultimate physiological phase that signals the end of fruit maturation and the beginning of fruit senescence. This stage is associated with increased ethylene production and a rise in cellular respiration.
Which of the following hormone is concerned with climacteric respiration ethylene auxin ga3 cytokinin?
During the process of ripening, ethylene, which has the chemical formula C 2H 4, speeds up the rate of respiration. The term ″climacteric respiration″ refers to this change in the rate of breathing.
What is the difference between ethylene and ethephon?
Phosphonate is the family to which the substance known as ethephon belongs.It acts as a systemic regulator of plant development.It is easily absorbed by the plant, and as a result, it produces ethylene, which is a hormone that occurs naturally in plants.The generation of endogenous ethylene is stimulated by ethylene, which in turn directly regulates various physiological processes (such as ripening and maturity, among others).
What is NAA hormone?
It is a rooting agent and is used for the vegetative multiplication of plants from stem and leaf cuttings. NAA is a synthetic plant hormone in the auxin family and is a component in many commercial plant rooting horticulture products. Additionally, it is utilized in the process of plant tissue culture.
Does gibberellic acid affect plants?
Gibberellic acids, also known as gibberellins, are plant hormones that exist naturally and are employed as plant growth regulators to accelerate both cell division and elongation, which in turn impacts leaves and stems. Gibberellic acids are also known as gibberellins.
What is the common function of auxin and gibberellin?
The Differences Between Auxin and Gibberellin
|Auxin does not help in breaking seed and bud dormancy.||Gibberellin plays a major role in seed germination, breaking seed and bud dormancy.|
|It promotes root formation.||It does not promote rooting.|
Which is the best plant growth regulator?
- Ethylene is the plant growth regulator that is utilized the most frequently because it assists in the regulation of a wide variety of physiological processes. Flowering should be induced in the mango tree
- Stimulates the growth of sprouts on potato tubers
- Causes seeds and buds to awaken from their slumber
- Increases the rate of respiration that occurs as fruits are maturing
What is the function of gibberellins in plants?
Gibberellins are a kind of plant growth regulator that, by encouraging the elongation of plant cells, let plants attain a greater height. They also play important roles in the process of germination, the lengthening of the stem, the ripening of the fruit, and the flowering of the plant.
