Question

Climacteric fruit is the one which shows

• A. Autochory
• B. High respiratory activity at ripening
• C. Sudden change in colour and taste at ripening
• D. Both A and B

Answer 1

Answer: (B)

High respiratory activity at ripening

Climacteric fruits are those fruits which are associated with increased ethylene production and high cellular respiration during ripening such as apple, banana, mango, melon, and apricot. Such fruits ripen after harvesting and it is not essential for them to remain on the tree for ripening. Increase in ethylene production triggers up their ripening process. Certain fruits such as citrus, grapes, and strawberries are non-climacteric as they ripen without ethylene and respiratory bursts.

Autochory is the process of dispersal of seeds and fruits because of some kind of natural physical explosion. It is a kind of self-dispersal of seeds.

Thus, the correct answer is option B.
