Effects of Pseudomonas putida strains on the anthocyanin pigment contents of the bracts of poinsettia plants.

Strain; P. putida	Poinsettia cultivars
	Prestige	Sonora Marble
Control	0.7427^a	0.3876^a
FCA-8	0.7230^ab	0.3371^a
FCA-56	0.6212^ab	0.3150^a

Mean followed by the same letter in a column is not significantly different (Tukey, 𝑃>0.05).
All plants were fertilized with the recommended commercial dose of 0.75 g L⁻¹ of NO₃ : P₂O₅ : K₂O (15 : 05 : 25), calcium nitrate (100 mg L⁻¹), micronutrients (60 mg L⁻¹), and molybdenum (0.05 mL L⁻¹).
MIX: plants simultaneously inoculated with strains FCA-8, FCA-56, and FCA-60 of P. putida.
