Natural seed abortion, also known as fruit drop or fruit abortion, occurs when a plant sheds immature or underdeveloped fruits or seeds. This process can be influenced by various factors, such as inadequate pollination, nutrient deficiencies, hormonal imbalances, diseases, or environmental stressors. The underlying causes of natural seed abortion can be complex and may differ among plant species.
Gibberellic acid treatment during fruit development can potentially improve fruit set and reduce fruit drop in some plant species. The hormone can promote cell elongation and division, leading to larger fruits with more developed seeds. By providing exogenous gibberellic acid, the plant's own natural production of the hormone may be supplemented, potentially enhancing fruit development and reducing seed abortion.
Therefore, statement Q is wrong. Hence, the correct answer is option 3.
