ABSTRACT

Toxic effect of aluminum on roots was studied using
seedlings of Capsicum annuum L. Subjected to water culture with different
concentrations of AlCl₃·6 H₂O (10, 20, 30 and 40 mg·dm^-3)
for a period of 14 days. Observations of red pepper root tissues were carried
out by light microscopy and scanning electron microscopy. The roots Al-treated
were characterised by an increased diameter, the shortening or absence of the
cap and cracks on the surface. The length of the elongation and meristematic
region was reduced. Disturbances in the arrangement, size and shape of the cells
of the apical section of the root were observed. The cells of the growing point
were characterised by disturbed division planes. The cells of precortex and primary
cortex underwent necrosis or showed symptoms of destruction. Many cells were
marked by hypertrophy and strong vacuolisation. In the vacuoles of the cells
of the investigated root section, numerous dark bodies were observed.

Key words: Capsicum annum, Al toxicity, root morphology and anatomy.
