The aim of this study was to evaluate the effect of high dilutions of Pulsatilla
nigricans in dinamisations 6, 12, 18, 24 and 30 CH on the vigour of soybean seeds
subjected to accelerated aging. The experiment was conducted according to a
randomised design with 6 treatments and 10 replicates. The treatments consisted of
dinamisations 6, 12, 18, 24 and 30 CH and a distilled-water control. After the
treatments, the seeds were subjected to accelerated aging (48h at 42ºC) in a growth
chamber (25 ± 2ºC). The study evaluated the germination, the length of primary roots
and shoots, the fresh weight of roots and shoots and the enzymatic activity of
peroxidase (POX-EC18.104.22.168). The variables were analysed by ANOVA, and the
means were compared using the Scott-Knott test (p = 0.05). The germination and the
fresh weight of roots and shoots of the seedlings treated with Pulsatilla nigricans
were higher than the water control, except that CH 30 did not significantly increase
the fresh weight of shoots. The dinamisations 6, 24 and 30 CH produced a lower
primary root length compared with the control. The dinamisations 12, 18 and 30 CH
yielded a greater length of shoots. The total length of seedlings was reduced by the
high dilutions 6 and 24 CH.
