    Abstract:
    Experiments for uptaking and distribution of the culm stabiliser "camposan" with the agens ethephon are very important to tell something about the dwarf behaviour of the treated plants of rye. The radioactive labelled ethephon is infiltrated through the roots, leaves and cuttings of culms. Uptaking through the roots is more complete than those about the foliar dissepiment. Otherwise uptaking through the foliar dissepiment is higher than about the leaves only. After radioautographic experiments, culmcutting-experiments and experiments with intact rye in the 5--6 leaf-stage we have found that the agens is transported acropetal in the xylem of the plants after uptaking by the roots up to 3 days. The labelled ethephon is translocated in a higher concentration in the phloem after foliar dissepiment application. The concentration of the agens decreases in the investigated plants up to the 5th day enormously (40--50% and after then slightly following the degradation to gaseous compounds. During 4 days ethephon is metabolized to about 5--15% ethylene and additional to about 18--20% carbondioxide.
