Question

Choose the correct answer from the alternatives given.
Fruit drop is caused by:

• A. absence of auxin in the stem
• B. less auxin in the fruit than in the stem
• C. more auxin in the fruit than in the stem
• D. equal distribution of auxin in the stem and fruit

Answer 1

The correct option is B less auxin in the fruit than in the stem

Deficiency of auxins, gibberellins, and cytokinins in fruit coupled with a high level of inhibitors appear to cause fruit drop.

So, the correct option is 'less auxin in the fruit than in the stem'.
