In climacteric fruits (such as tomato, banana, apple and peach) the ripening progression is controlled by ethylene, a plant hormone highly synthetized during the late ripening stage. This burst is moreover accompanied by a rise in respiration rate.

Which of the following hormone is concerned with the climatic respiration?

Ethylene promotes senescence and abscission of plant organs especially of leaves and flowers. Ethylene is highly effective in fruit ripening. It enhances the respiration rate during ripening of the fruits. This rise in rate of respiration is called respiratory climactic.

Which plant hormone is involved in respiration climacteric?

ETHY was also highly sensitive to changes in fruit growth and temperature. The plant hormone ethylene (C₂H₄) plays a major role in the ripening process of climacteric fruits.

Which plant hormone can be used to ripen climacteric fruit?

During flooding, for instance, ethylene induces the formation of aerenchyma tissue (consisting of air-filled cavities) for oxygenation. Ethylene is best known, however, for its essential role in the ripening of climacteric fruits, such as tomatoes, bananas, pears and apples.

What is the role of ethylene hormone in plants?

Ethylene is regarded as a multifunctional phytohormone that regulates both growth, and senescence. It promotes or inhibits growth and senescence processes depending on its concentration, timing of application, and the plant species. ... Ethylene governs the development of leaves, flowers, and fruits.

What is triple response of ethylene?

Ethylene causes what is known as the "triple response" in plants: it causes plants to have short shoots, fat shoots, and increased lateral root growth. ... Inhibition of cell expansion contributes to "thigmotropism" in plants, which is an inhibition of cell expansion by ethylene in response to physical contact.

Which of the following hormone stimulates ethylene release?

Auxin induces ethylene production, and many effects of exogenous auxins are, in fact, ethylene responses (Abeles et al., 1992).

Which of the following is a ripening hormone?

Ethylene is a plant growth regulator or hormone which induces the ripening process in fruits and it hastens the process of ripening. Commercially, ethylene gas is used for fruit ripening.

What are plant hormones 10th?

Plant hormones are chemical compounds present in very low concentration in plants. They are derivatives of indole (auxins), terpenes (Gibberellins), adenine (Cytokinins), carotenoids (Abscisic acid) and gases (Ethylene). ... Roles of different hormones can be complementary or antagonistic.

Which of the following hormone prevents ripening of fruit?

Answer. Hi, The ethylene is a plant hormone which is transported through the spaces between the plant cells. Ethylene is gaseous in nature.

Is ethylene a gaseous hormone?

Ethylene, the Gaseous Plant Hormone.

Which one of the following is synthetic cytokinin?

2,4-5 trichlorophenoxypropionic acid.

What are plant hormones?

Plant hormones (also known as phytohormones) are organic substances that regulate plant growth and development. Plants produce a wide variety of hormones, including auxins, gibberellins (GA), abscisic acid (ABA), cytokinins (CK), salicylic acid (SA), ethylene (ET), jasmonates (JA), brassinosteroids (BR), and peptides.

What is climacteric respiration?

Climacteric is the final physiological process that marks the end of fruit maturation and the beginning of fruit senescence. Its defining point is a sudden rise in respiration of the fruit, and normally takes place without any external influences.

What is the respiratory climatic?

Ethylene facilitates the respiration rate in the process of ripening of fruits. This surge in the rate of respiration is referred to as respiratory climactic. Stay tuned to BYJU'S to learn similar NEET Questions.

What is natural cytokinin?

Cytokinin is a naturally occurring plant growth hormone (PGR) extracted from coconut milk. Cytokinins are synthesized in root apex, endosperm of seeds, and young fruits where cell division takes place continuously.

What are 12th hormones?

Hormones are various chemicals released within a human body that regulate and control the activities of multiple organs. The introduction of hormones to the blood takes places via endocrine glands. What Is the Function of Hormones? Hormones act as a messenger which are released into the blood.

What are plant hormones class 10th answer?

Plant hormones are chemicals present in plants which help to coordinate growth, development and responses to stimuli and environment. For example, auxins, gibberellins, cytolcinins, abscisic acids are different plant hormones.

What are the 5 plant hormones?

5 groups of plant-growth-regulating compounds. There are five groups of plant-growth-regulating compounds: auxin, gibberellin (GA), cytokinin, ethylene, and abscisic acid (ABA). For the most part, each group contains both naturally occurring hormones and synthetic substances.

What is the function of ethene?

Ethene is a hydrocarbon gas which speeds up ripening in bananas and other fruit as well as causing dropping of leaves. It also controls cell division during plant growth. In the food industry fruit is often picked unripe and then transported. This prevents fruit from over-ripening on the journey.

Which of the following hormone induces cell division?

Cytokinins. The cytokinin hormones promote cell division and tissue growth, and depend upon the presence of auxins to determine the extent of their activity.

What is action of ICI on ethylene?

Answer: Ethylene is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in 2016) exceeds that of any other organic compound. ... Ethylene is also an important natural plant hormone and is used in agriculture to force the ripening of fruits. The hydrate of ethylene is ethanol.

Why is ethene considered a fruit ripening hormone?

Ethylene is the major compound used to aid fruit ripening. When a fruit ripens it produces a lot of Ethyleneand carbon-di oxide. For example, if you close a ripen banana with unripe apples, the Ethylene produced by the Banana would increase the ripeningprocess of the apple. Hence, you getripened fruits faster.

What are the 3 steps of triple response and the hormones involved?

Ethylene-induced inhibition of hypocotyl and root elongation, induction of radial swelling, and the formation of an exaggerated apical hook comprise the three components of what is frequently referred to as the triple response (Guzmán and Ecker 1990; Abeles and others 1992).
