Effect of diammonium phosphate on germination of the seeds of congress
grass (Parthenium hysterophorus L.). finger miller [Eleusine coracana
(L.) Gaertn.] and wheat (Triticum aestivum L. emend. Fiori & Paol.) w
as investigated. The sensitivity of the seeds to diammonium phosphate
(18% N, 46% P + inert material) during germination was in the order: c
ongress grass > finger millet > wheat. The germination of these seeds
was completely inhibited by diammonium phosphate (w/v) respectively at
0.25, 2.5 and 5.0% concentrations; and by 50% at 0.1, 2.4 and 4.2%. T
he dehydrogenase activity in the seeds of congress grass appeared more
sensitive to diammonium phosphate concentration than in those of fing
er miller and wheat. A major reason for relative tolerance of the latt
er 2 crops to higher concentrations of diammonium phosphate appears to
be the retention of higher levels of dehydrogenase activity and thus
higher level of mitochondrial functions.
