Abstract
Absorption of Mn by root and its distribution vary among plant. Some species accumulate more Mn in the root while others accumulate more Mn in the top. Besides accumulation of Mn in the tissue is time dependent. Two sets of experiment were conducted at the UPM glasshouse during the periods of October-December 1995 and September-December 1996. In the first study 9 levels of Mn concentration 0 75 150 225 300 375 450 525 and 600 mM were used in a sand culture experiment to determine the distribution of Mn in soybean root stem leaves and pod. In the second study 2 levels of Mn concentration 5 and 25 muM were applied in solution culture experiment to determine the timing of the accumulation of Mn in the tissue. It was found that Mn was more concentrated in the leaf than the other parts of the tissue. Manganese concentration in the leaf was 45 mg gE-1 tissue when the Mn rate 75 muM. The concentration increased to 130 mg gE-1 when the rate was 450 mM. Other parts of the tissue stem root and pod accumulated only 15 mg gE-1 when Mn rate was 75 muM. The concentration increased to 54.41 mg gE-1 in the root 43.28 mg gE-1 in the stem and 38.53 mg gE-1 in the pod when the rate was 450 muM. The accumulation Of Mn in middle leaf was reduced when the time was prolonged in both of the treatments 5 and 25 muM Mn. The increase in Mn accumulation would increase N P K concentrations in the tissue under both of the treatments 5 and 25 muM Mn. The study showed that Mn accumulation affected soybean growth.
