Show Hint
Avoid over-fertilizing pineapple crops with nitrogen during early vegetative phases to minimize the risk of fasciation.
Balanced nutrition with adequate potassium helps maintain proper meristematic development.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Fasciation (spelled "fascination" in the question paper) is a physiological disorder characterized by abnormal, flattened, or ribbon-like growth of plant organs.
In pineapple (Ananas comosus), it affects the fruit development and the crown, rendering the fruit unmarketable.
Step 2: Detailed Explanation:
In pineapple, fasciation causes the fruit to become excessively broad, flat, and multi-headed with multiple crowns.
This disorder is strongly linked to high plant vigor.
When plants grow too rapidly due to excess nitrogenous fertilizers, warm temperatures, and abundant water, the apical meristem undergoes abnormal cell division.
This cellular malfunction spreads horizontally instead of vertically, leading to fasciation.
Consequently, highly vigorous plants are more prone to this disorder, whereas weak plants are rarely affected.
Additionally, the incidence of fasciation increases significantly in ratoon crops.
Ratoon plants utilize the well-established root system of the mother plant, allowing them to absorb nutrients and water very quickly.
This rapid absorption leads to high vegetative vigor and increases the risk of developmental anomalies like fasciation.
Therefore, fruit and crown fasciation is associated with vigorous pineapples, and its incidence increases with ratooning.
Step 3: Final Answer:
Fasciation is a pineapple disorder associated with highly vigorous plants and increases in ratoon crops.
