Abstract
Three propagation methods by seeds, cuttings and micropropagation of
Jatropha curcas L. have been conducted in plant tissue culture laboratory and
experimental farm of Faculty of Environmental Agricultural Sciences -EL-
Arish. North Sinai, Suez Canal University to identify the best propagation
method of Jatropha curcas L. Seed propagation was conducted in the two
successive seasons of 2009 and 2010 to determine the best pre-treatment of
seeds( soaking in warm water for 12 hr - soaking in tap water for 24 hr - seed
clipping -seed scarification and the control ) suitable for the germination of
J.curcas seedlings. The results indicate that pre - treatment of seeds
( scarification and clipping) gave higher germination percentage and rate and
highest values in seedling stem height, root length, number of leaves, dry matter
of” leaves, stem, roots” and higher chlorophyll content. The effects of Indole-3-
Butyric Acid ( IBA) concentrations ”500, 1 000, 1500 mg/L” on rooting and
sprouting behaviors of stem cuttings of .Lcurcas under field conditions have
been conducted also in the two successive seasons of 2009 and 2010. pre-
treatment with ”IBA” especially concentration of IBA ( 1500 mg/L ) increased
sprouting, rooting and survival percentage of cuttings more than other
concentrations of IBA and control treatment.
