Embryogenic Callus Induction

To explore the potential for embryogenic callus induction protocol through cell suspension culture forhigh frequency plant regeneration of Maspine pineapple (Ananas comosus L.), eight different culturemedia formulation were evaluated for their effects on the induction of somatic embryos from suckerexplants. Explants were cultured on MS medium supplemented with various media concentration(NAA, Dicamba and BAP, Picloram, Kinetin and NAA, 2,4-D, TDZ, and TDZ and BAP).Embryogenic callus induction percentage, color and texture of the callus were assessed after fivemonths of culture. The optimum medium for the proliferation of in vitro shoots from sucker explantswas MS medium supplemented with 3 mg/L BAP. Meanwhile, the optimum medium for the inductionof fastest and high percentage of embryogenic callus growth from in vitro leaf-based was MS mediumsupplemented with Picloram. Results of mean comparison showed that 3 mg/L Picloram were moreeffective on explants than 10 mg/L. Results of the double staining method proved that somaticembryogenesis occurred in MS supplemented with 3 mg/L Picloram. Under microscopic observations,the globular-stage of the embryos were revealed in callus cells which is relatively suitable forsuspension cells inoculums, indicating that the tested PGR were significantly effective for somaticembryogenesis formation in this species. Most embryogenic callus from sucker explants wasyellowish-mucilaginous-wet-friable. The developed protocol potentially leads to the production ofembryogenic callus from sucker explants and plant regeneration through somatic embryogenesis.

Embryogenic Callus Formation

Significant variations were observed among six elite Bangladeshi Indica rice cultivars tested in relation to total callus induction frequency (p = 0.017), embryogenic callus formation frequency (p = 0.001) and subsequent plant regeneration responses (p = 0.005). In all the cases, embryogenic callus formation frequency was much more less than the total callus (embryogenic + non-embryonegic) formation frequency. The embryogenic calli derived from mature seed embryos produced green plants, successfully established in soil and produced fertile seeds.Key words: Indica rice, Callus induction, Plant regeneration, Genotypic variationsDOI = 10.3329/ptcb.v17i1.1122Plant Tissue Cult. & Biotech. 17(1): 65-70, 2007 (June)
