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 Induction

<p>Somatic embryogenesis is a technique for regenerating embryos derived from somatic cells of various plant species. This technique along with the utilization of plant growth regulator (PGR) might benefit for mass propagation and improvement of plant species through biotechnological tools. The study aimed to determine the effect of different plant growth regu-lators, namely 6-benzyladenine (BA) and thidiazuron (TDZ) on the embryogenic callus induction as well as casein hydrolysate and malt extract on the somatic embryo development of mangosteen. The explants used were in vitro young stems of mangosteen clone Leuwiliang. This study consisted of two experiments, namely induction of embryogenic callus and formation of somatic embryo. The first experiment was arranged as factorial in a completely randomized design with BA (0 and 0.7 mg l-1) as the first factor and TDZ (0, 0.1, 0.5 and 1.0 mg l-1) as the second factor. The second experiment consisted of four treatments, i.e. casein hydrolysate and malt extract at the rate of 500 and 1,000 mg l-1. The results showed that the best medium for embryogenic callus induction was MS supplemented with 0.1 mg l-1 TDZ, which resulted semifriable calli. Casein hydrolysate and malt extract could not induce the formation of somatic embryos. After two times subcultures on the same MS medium supplemented with 0.5 mg l-1 TDZ and 0.7 mg l-1 BA, a total of 33.8 somatic embryos per explant was induced. The successful somatic embryogenesis would support mangosteen breeding and in vitro mass propagation program.</p>

Aquilaria malaccensis Lam. and Aquilaria subintegra Ding Hou belong to the family of Thymelaeaceae which is commonly known as gaharu or agarwood. It is a commercially important tree and identified as a potential aromatic plant. The overwhelming responses in the lodging sector reduce gaharu species in the forest. Mass propagation through plant tissue culture technology will substitute this problem. The present study was conducted to investigate the embryogenic callus induction between these two species. The most optimum sterilization method for both species was sodium hypochlorite 5.0% which gave the highest percentage of aseptic culture (95%) with the absence of tissue browning. The leaves of both species were cultured on Murashige and Skoog, (1962) (MS) media supplemented with combination of various concentrations of 6-benzylaminopurine (BAP) (0.5, 1.0, 2.0 and 2.5 mg/L) and 2,4-dichlorophenoxyacetic acid (2, 4-D) (0.5, 1.0, 1.5 and 2.0 mg/L) and kept under dark condition. The explants produced embryogenic, white and compact callus at the end cut of the explants after two weeks of culture in all treatments. The highest frequency of embryogenic callus formation was observed in explants cultured on 2.0 mg/L BAP and 0.5 mg/L 2,4-D for both species. From the present study, the optimum sterilization technique and embryogenic callus induction for A. malaccensis Lam. and A. subintegra were established.
