Effects of Pseudomonas putida strains on growth promotion of poinsettia Prestige cultivar.

Strain; P. putida	Fresh biomass		Area of bracts (cm^2)
	Leaves	Bracts
Control	68.24^c	40.2^b	1,862.6^b
FCA-8	79.25^abc	48.1^ab	2,440.3^a
FCA-56	78.58^abc	45.6^ab	2,010^b
FCA-60	83.32^ab	51.7^ab	2,173^ab

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.
