Physiological disorder
✅Explanation: Physiological disorder is the most likely cause of blind shoots in roses. Blind shoots are flowerless stems that develop on rose bushes. While the exact cause is not fully understood, several factors can contribute to their formation, including:
-Temperature Fluctuations: Significant swings in day and night temperatures during growth stages can disrupt flower bud development.
-Nutrient Imbalance: An improper balance of nutrients, particularly a lack of boron or potassium, can affect flower formation.
-Insufficient Light: Roses need adequate sunlight for healthy growth and flower production. Shaded conditions can promote blind shoots.
-Hormonal Imbalance: Disruptions in the plant's natural hormone balance can lead to blind shoots.
