Slow Growth on pothos
What's Happening
Pothos (Epipremnum aureum) responds to exogenous estrogenic compounds via cytokinin-like action, triggering enhanced morphological development. Research demonstrates ethinyl estradiol at 0.1 ppm increases plant height, leaf area, and fresh/dry weights of above-ground parts through activation of estrogen receptors in plant tissue or induction of endogenous cytokinins. Optimal BA (2.5 mg/L) + Kn (1.0 mg/L) combinations produce 2.86 shoots per explant with 1.87 cm shoot length for mass propagation.
How to Fix It
- 1
For enhanced growth: Apply ethinyl estradiol at 0.1 ppm via drenching during peak growth periods
- 2
For propagation: Use MS medium with 2.5 mg/L BA + 1.0 mg/L Kn for optimal shoot proliferation
- 3
Transfer micro-shoots to MS + 0.25 mg/L α-NAA + 0.5 g/L activated carbon for 93.33% rooting success
- 4
Acclimate in 1:1 loamy garden soil and coconut coir mix for 75% survival after 40 days
How to Prevent It
Apply diluted growth regulators only during active growth seasons (spring-summer). Maintain consistent nitrogen and phosphorus levels to support enhanced metabolic demands from hormonal stimulation.
