Abstract
Polyamines were analyzed in young cotyledons of spring radish. The uptake rate of SPD were transported within 20 min lineary and reached the saturation phase after 1hr. The uptake rate of SPD decreased gradually with the time by the increasing amount of SPD inside the cells. The uptake of PA depends on the external pH. The optimal pH of PA uptake are pH 7.5. <TEX>$K_m-$</TEX> and <TEX>$V_{max}-$</TEX>values depend on external pH also. The uptake rate of PA was inhibited by external KCI, which depolarized membrane potential in the cells.
