THE RELATIONSHIP BETWEEN ETHYLENE AND AUXIN ON ADVENTITIOUS ROOT INITIATION IN CUTTINGS OF CUCUMBER

A.F. Abou Hadid
The application of Ag+ as silver thiosulfate and Co+ as cobalt chloride in combination with Indolebutyric acid (IBA) was tested in regards to its effect on root initiation of cucumber. The effect of heavy metal ions on ethylene biosynthesis and the relationship between ethylene and auxin on adventitious root formation were demonstrated. Preliminary results indicated that endogenous levels of ethylene were initially higher in cuttings treated with IBA which significantly inhibited rooting in cuttings treated with silver thiosulfate, but its inhibitory effect could be attributed to increased ethylene biosynthesis.
