Which of the following is a function of ethene?
A
It can be used to alter dormancy
B
It stimulates seed germination
C
It induces flowering
D
It stimulates the enzyme that causes fruit to ripen
Explanation: 

Detailed explanation-1: -What is the important function of ethylene in plants? Ethylene acts as a plant growth regulator. It accelerates the development process in plants such as senescence, ripening, and abscission.

Detailed explanation-2: -Ethylene is a gaseous plant hormone that plays an important role in inducing the ripening process for many fruits, together with other hormones and signals. An unripe fruit generally has low levels of ethylene. As the fruit matures, ethylene is produced as a signal to induce fruit ripening.

Detailed explanation-3: -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.

Detailed explanation-4: -Ethylene: ↑ A gas (C2H4) produced by plants, and known as the “ripening hormone, ” which stimulates fruit ripening.

Detailed explanation-5: -Abscisic acid (ABA) and ethylene are the major regulators of ripening and senescence in both dry and fleshy fruits, as demonstrated by numerous ripening-defective mutants, effects of exogenous hormone application, and transcriptome analyses.
