Abstract

Iron-stress tolerance and susceptibility were examined in two sorghum (Sorghum vulgare Pers.) hybrids CSH-7 and CSH-8 and compared with those of their parents, 36-A, 168 and PD-3-1-11. The capacity to reduce the pH of the root medium and recovery from chlorosis were significantly greater in the two hybrids which manifested hybrid vigour or heterosis in their iron-stress response. Further, it is suggested that the chlorotic leaf of an iron-stress tolerant variety transmits a "signal' to the root and this "signal" is probably hormonal in nature.
