Abstract
This study was carried out in both of Plant Tissue Culture Laboratory and Medicinal and Aromatic Plant research Station of Olericulture and Floriculture Dept., Fac. Agric., Mansoura Univ. to attain two main purposes. The first was finding an efficacious method to propagate Egyptian taro crop by plant tissue culture technique and the second was evaluation of field performance of taro plants obtained from tissue culture as compared with conventional planting materials used in commercial propagation of this plant. This study had been carried out during the period from 2002 to 2005. All in vitro experiments were laid out as completely randomized design, while, in vivo experiments were designed as a randomized complete block design, and all means of obtained data were compared by Duncan’s test except in establishment experiment, data were statistically analyzed using standard error (S.E.). • This study revealed the following results :- A. In vitro part. 1. Using meristem tips of axillary buds of taro corm in establishment stage. 2. Culturing of taro shoots for 8 weeks on MS medium with 1.0 mg TDZ /l in multiplication stage. 3. Subculturing of healthy taro shoots in the same medium for 7 weeks for obtaining the best multiplication rate of shoots. 4. Rooting taro shoots on rooting medium containing MS medium plus 1.0 mg NAA /l + 60 mg PG /l. 5. Adaptation of taro plantlets in agricultural medium including a mixture of peat moss : vermiculite : perlite : sand at 1:1:1:1, v/v/v/v. B. In vivo part. 1. Application of adapted transplants regenerated from plant tissue culture technique as a new method for propagation is better than the traditional methods i. e. (apical piece, corm piece and cormel) in field cultivation of taro plant for its several advantages
