| Summary: | Acidic soils are approximately 35% of arable soils and
one of the most important limitations in agriculture.
The restriction in the growth and production of the
culture with a pH lower than 5.0 is mainly due to
the formation and migration of aluminum ions (Al3
+). With this background, the growth toxicity of
two varieties of Phaseolus vulgaris L. var. “canario”
and var. “panamito” was analyzed. The completely
randomized experimental block design had the treatments of 50 µM, 25 µM and 0 µM, with three
repetitions each. The seedlings were adapted in a
hydroponic system, which contained the modified
Hoagland nutrient medium and the different
concentrations of aluminum. After three days root
length, fresh and dry weight, accumulation of the
metal in leaves and roots, peroxidase activity, protein
percentage were evaluated. The panamito was more
sensitive in relation to the canario according to the
evaluated variables. Aluminum accumulation was
greater in the leaves for the panamito and in the roots
for the other variety. It is concluded that the canario
is more tolerant than the panamito variety |
