Which of the following fruits is commonly affected by blossom-end rot disease?

✅Explanation:
Watermelon is a common fruit that is susceptible to blossom-end rot. This physiological disorder is caused by calcium deficiency in the fruit, often resulting from inconsistent watering or nutrient imbalances.

• Why Watermelons are Susceptible:
Rapid Growth: Watermelons grow quickly, outpacing calcium supply.
Calcium Mobility: Calcium is not easily transported within the plant.
Water Stress: Fluctuating moisture levels disrupt calcium uptake.
High Temperatures: Increase water loss and limit calcium uptake.
Nutrient Imbalances: Excess nitrogen favors vegetative growth over fruit development.
Cultivar Susceptibility: Some varieties are more prone to blossom-end rot.
