The experiment was carried out at the Experimental Farm of Faculty of
Environmental Agricultural Sciences. in El-Arish, Suez Canal University. during 2000-
2001 and 2001-2002 seasons. The main object of this research was to study the
effect of fSA concentrations and different media types and their interactions on the
vegetative growth and chemical constituents of Hibiscus rose-sinensis l. nurslings. The obtained results showed that dipping Hibiscus rosa-sinensis l. semi
hard stem cuttings in ISA up to 4 000 P pm for 3 0 second enhanced fresh and dry
weights of root and shoots (leaves + stems) in addition to leaves number and shoots
height I nursling. The tested media including [peatmoss, sand, composted olive cake
and mixtures of peatmoss + sand, peatmoss + composted olive cake. sand +
composted olive cake at rate of (t.t-v.v) and mixture of peatmoss + sand +
composted olive cake at rates of (1:1 :l-v.v)] showed that cornposted olive cake media
alone or combined with peatmoss (1:1) proved to be the efficient media to raise the
nurslings concerning the vegetative characters. Also, the interaction treatments
between the tested media and ISA were significani and indicated that the best
combination treatment for raising the nurslings was dipping cuttings in 16A at 4000
ppm and planted them in composted olive cake medium or composted olive cake +
peatmoss medium. The highest percentages of NPK and total carbohydrate in the
leaves were also obtained from the previously mentioned treatments, hence using
composted olive cake media in raising the nurslings of Hibiscus rose-sinensis L. under
Sinai conditions can be advised since it is available as a side product of olive oil
pressing manufacture which save the costs of USing peatmoss.
