Consider the effects of different hormone treatments on plant growth and development:
A. Seedlings are treated with gibberellin followed by abscisic acid. This hormone sequence promotes stem elongation and seed germination followed by inhibition of growth, reflecting the dynamic balance between growth promotion and stress responses in plants.
B. Seedlings undergo a treatment with cytokinin followed by auxin application. This hormone sequence induces cell division and differentiation, stimulating lateral root formation and shoot branching, crucial for overall plant growth and development.
C. After exposure to auxin, seedlings are treated with gibberellin. This hormone sequence initiates cell elongation and expansion, promoting stem and leaf growth, essential for plant architecture and canopy development.
D. Seedlings are initially treated with abscisic acid, followed by cytokinin application. This hormone sequence triggers stomatal closure and drought stress responses, followed by activation of cell division and shoot growth, allowing plants to adapt to changing environmental conditions.
E. Following treatment with auxin, seedlings are exposed to ethylene. This hormone sequence regulates root development and gravitropism, followed by promotion of fruit ripening and senescence, playing critical roles in plant growth and reproduction.
F. Seedlings undergo treatment with ethylene, followed by gibberellin application. This hormone sequence initiates leaf abscission and fruit ripening, followed by promotion of stem elongation and flowering, marking the transition from vegetative to reproductive growth stages in plants.
Which of the above hormone treatments leads to optimal plant growth and development?
