Root-tips, 1-cm, of Sorghum bicolor (L.) Moench cv SC283, SC574, GP-10, and Funk G522DR were exposed to 1 mM PCMBS for 10-min and then to 45Ca2+ in the presence of cation channel blockers nifedipine (0, 0.001, 0.01, 0.1, or 1.0 μM), diltiazem (0, 0.001, 0.01, 0.1, 1.0, or 10.0 mM), or verapamil (0, 0.01, 0.1, 1.0, or 10.0 mM)] at pH 5.5 for 2-hr. Significant differences in total 45Ca2+ absorption between cultivars without cation channel-blockers was observed. Each channel-blocker was effective at concentrations that were interactions of channel-blocker and cultivar.
