چکیده
ABSTRACT Flame retardants are efficient in fighting wildfire; however, their environmental implications, especially regarding the vegetation, need to be clarified. This work aimed at assessing effects of flame retardant on initial growth Schizolobium amazonicum. Treatments consisted applying different concentrations via substrate and leaf: Phos-Chek WD-881® (0, 3.00, 6.00, 8.00 10.00 mL L-1), Hold Fire® 7.00, 9.00, 12.00 15.00 L-1) water-retaining polymer Nutrigel® used as alternative 0.25, 0.50, 0.75 1.00 g L-1). Growth analyses were carried out assess these substances (10 repetitions per treatment). The aliquot L-1 WD881 applied leaves led an increase 70% leaf area 15% seedling height. same concentration favored height (32%) total dry mass accumulation (33%) throughout time. 15 leaves, compromised 45% biomass seedling. Initially, area, 29% plant height, 89% mass. Therefore, shoot S. impaired seedlings. does not cause long-lasting damage 0.50 administered leave had positive effect shoot.
