Abstract excerpt
Responses to Al3+ of embryogenic callus cells of an Al-sensitive (Al-S) and Al-resistant (Al-R) Cynodon dactylon genotype were evaluated with regard to Al3+ toxicity and resistance. A chemical equilibrium speciation model (MINTEQA2) was used to ensure the availability of the Al3+ ion in culture media, which was supplied as 0.08-2.3 mM Al3+ for 2-8 weeks. Increasing Al3+ concentration and exposure time had a...
