| Abstract | ||||
| 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. | ||||
