Aim: To evaluate the
effect of different rooting media and naphthalene acetic acid on rooting
abilities and shoot growth of Nerium oleander cuttings.
Red and Petite Salmon (Dwarf Nerium), the experiment was designed randomly to
obtain data from three replicates (ten cuttings per replicate). The cuttings
taken during mid February were rooted at different concentrations of NAA (500
and 1000 mg l-1) and in growth media (peat, per lite and municipal
sewage sludge) for 45 days. The shoot length and number, fresh and dry weight
of shoots, rooting ratios, root number and length, fresh and dry weight of
roots were measured.
results showed that the best rooting medium was peat and 500 mg l-1
of NAA increased rooting ratio by 60%, no difference was found between other
two NAA concentrations. Moreover, in both varieties, peat growth media plus
500 mg l-1 NAA yielded the best results and addition of NAA
positively affected shoot fresh and dry weight.
the basis of this study, it can be concluded that peat was found to be the
best rooting media and NAA addition in rooting media positively affected
plant growth. Moreover, recycled municipal sewage sludge can be used in
ornamental plant cultivation.
