摘要:
Setaria and paspalum were found to be very tolerant of excess Mn. Green panic and sorghum were somewhat less tolerant with foliar symptoms due to excess Mn being exhibited in plants containing 1000 ppm Mn and yield reductions occurring in plants containing Mn concentrations of the order of 2000 ppm. Excess Mn did not effect the early seedling growth of sabi grass but regrowth was severely depressed. Rhodes grass and buffel grass were severely effected by excess manganese. Regrowth of these two species was more adversely effected than initial seedling growth indicating that these species probably would not survive to maintain a stable pasture in Mn toxic situations.
