| In germinating pea, contents of enodgenous polyamine in the leaf and stem were determined, and protein content, peroxidase activity and pattern of isozymes were examined in the leaf treated with polyamines. During growth of the pea for 14 days in light condition, the polyamines in leaf and stem showed the highest level at the 5th day, and were decreased rapidly at the 7th day, kept almost constant level since then. The putrescine level was relatively higher than those of spermidine and spermine, and cadaverine was also detected. On the other hand, in the leaf treated with spermine (0.01 mM) protein content increased about 250% than that of the control, the peroxidase activity increased ore than 100% in spermine of 0.01 mM and 0.1 mM. In treating with putrescine of 0.1 mM the pattern of peroxidase isozyme appeared 4 new cathodic bands (pI 4.8, 5.6, 5.9 and 6.8) compared with the control, the clear cathodic bands (pI 5.6, 5.9, 6.4 and 6.6) were also observed in spermine of 0.1 mM. These results suggest that polyamines were important factor in the differentiation of pea at the early stage of germination. |
