-
Promotion of Shoot and Bud Development: 6-BA stimulates shoot proliferation in tissue culture and encourages lateral bud development in adult plants. This makes it valuable in ornamental horticulture and crop propagation.
-
Delaying Senescence: It inhibits chlorophyll degradation, thereby prolonging leaf lifespan and improving photosynthetic capacity.
-
Stress Tolerance: 6-BA can enhance plant tolerance to abiotic stresses such as drought and cold by regulating hormonal balance and antioxidant enzyme activities.
-
Fruit Set and Yield Enhancement: Exogenous application of 6-BA can induce flowering, increase fruit set, and improve the quality and size of fruits in crops like citrus, grapes, tomatoes, and berries.
-
Regulation of Nutrient Utilization: Cytokinins, including 6-BA, help in efficient nutrient allocation from older tissues to younger growing tissues, optimizing plant growth.
