Abstract. This study was conducted in the tissue culture laboratory at
the Department of Arid Land Agriculture, Faculty of Meteorology,
Environment and Arid Land Agriculture, King Abdulaziz University,
Jeddah. It aimed to study the effect of BA and IBA concentrations on
shoot tips multiplication and rooting formation under Murashige and
Skoog medium with Yucca elephantipes micropropagation.
The results showed that BA with 2, 3 and 1 mg/l concentrations
produced the highest number of developed vegetative branches with
values of 8.750, 6815 and 5.625, respectively, but the zero BA did not
produce any developed branches. No significant differences were
shown for the vegetative branches heights under the effects of the
studied BA concentrations (from 1 to 7mg/l).
Also, the effects of IBA concentrations on rooting of plantlets of
Yucca elephantipes roots under the Murashige and Skoog medium
were studied. The results showed that the 1 mg/l IBA produced the
highest number of roots (18) and equally significant with the 0.6 mg/l
IBA which produced 14 roots. But it differed from the 0.2 and 0.4
mg/l concentrations which produced 10 roots. The highest root length
was produced from the concentrations of 1 and 0.4 mg/l IBA with
values of 15.666 cm and 14.813 cm, respectively.
Concerning transplanting and acclimatization, all Yucca plants
were acclimated then, they were transported to the greenhouse in the
Agricultural Experimental Station in Hada El-Sham. |
