What are the reasons behind flower and fruit drop in plants? (CG RHEO 2017)

✅Explanation: Flower and fruit drop in plants can occur due to a combination of factors:
-(a) Development of abscission layer: This is a natural process where a plant forms a specialized layer of cells at the base of a flower or fruit. When triggered by various factors (such as hormonal changes, lack of pollination, or stress), the abscission layer weakens and eventually severs the flower or fruit from the plant.
-(b) Lack of nutrition: Inadequate nutrition, especially deficiencies in essential nutrients like nitrogen, phosphorus, potassium, or micronutrients, can hinder flower and fruit development, leading to their premature drop.
-(c) Environmental factors: Environmental stresses like extreme temperatures, insufficient light, wind, or fluctuations in humidity can disrupt plant growth and lead to flower or fruit drop. Plants may abort flower or fruit development to conserve resources during unfavorable conditions.
-(d) Insect and disease: Insect pests and diseases can damage flowers and fruits, making them susceptible to premature drop.
