This study showed Strut Lifter Switch that rooting is strongly affected by natural leaf drop occurring during cutting collection.Observations carried out during sampling showed that cultivars with more than 80% leaf drop had lower rooting percentages than cuttings from cultivars with leaf drop between 44 to 75%, and that generally, the peaks of leaf drop coincide very closely with low rooting.Besides, it was found that there is a relation between Fe and N content in the bark of cuttings and their rooting.The peaks of Fe content coincide with the peaks of rooting.In contrast, the peaks of N content Phosphatidylserine coincide with the lowest percentage of rooting.
Overall, there seems to be no clear-cut relation between rooting and contents of P, K, Ca, Mg, Mn and Zn.
