摘要
Calcium (Ca2+) and aluminum induced unilateral root growth inhibitions (i.e. root curvature) when applied in agar to one side of sorghum [Sorghum bicolor (L.) Moench] roots. PCMBS (p-chloromercuribenzenesulfonic acid) (10 mM) stopped the root growth inhibition (i.e. curvature) by aluminum in SC574 and SC283 (acid-soil-stress tolerant cultivars) but not in Funk G522DR (acid-soil-stress sensitive). PCMBS influenced Ca2+-induced root growth inhibition (i.e. curvature) in Funk G522DR and SC283, but not in SC574.
