Question

Which of the following is use to enhance colour of fruits and more juice in fruits unnaturally?

• A. Sodium chloride
• B. IAA
• C. Ethylene gas
• D. Kinetin

Answer 1

The correct option is C Ethylene gas

Exposure to ethylene enhanced peel color break, and respiration. The plant hormone ethylene plays a major role in the ripening process of climacteric fruits and the presence of ethylene and its perception is required for the expression of ripening-related genes even at advance stages of fruit ripening.

IAA is the main auxin present in the plants. It regulates cell expansion, differentiation, division, etc. IAA promotes apical dominance by inhibiting lateral bud growth. IAA is present in the apical bud that inhibits the growth of lateral or axillary buds. Sodium chloride has an effect on almost all the aspects of plant development which includes – germination, vegetative growth and even reproductive development. Kinetin is a cytokinin-like synthetic compound that regulates cell growth in plants.

So, the correct answer is "Ethylene gas"
