“…The hypocotyl explants of F.vulgare were successfully induced on MS, NN and SH basal media with PGR for callus formation. These observations conforms to the earlier observations on callus induction from hypocotyl and radical explants of Asparagus densiflorus on MS medium (21), whereas in vitro cultures of fennel reported 100% callus formation on MS medium with IAA, Kn and 2-iP each at 0.5 mg/l (3). Similarly, hypocotyl and radical explants of Asparagus densiflorus were induced to maximum callus induction and proliferations (95%) on MS medium with 0.5 mg/l BA and 0.3 mg/l NAA (21), while in Ammi majus cotyledonary leaves produced callus on MS medium supplemented with 2 mg/l IAA, 0.5 mg/l Kn and 40 ml Adenine (14).…”

“…Peters et al (1976) have reported that~ regeneration efficierlcies are very low in a kinetin-free medium, and that root formation is significantly enhanced in media supplemented with IAA, kini~tln, and 50 mg/mL ni(:otine as alkaloids. These developmental steps have also been reported by Halperin (1966), Nuti Ronchi (1981), Davies et al (1982), Howarth et al (1983), and Anzidei et al (1996). !h our study, calli developed from the excised stem fragments, originating from the cambium cells that were formed from the connections of actively dividing Concurrently, most of the explant ceils, including the vascular bundle and pith, became meristematic and started to divide.…”

We have established a reproducible culture system for callus formation and root development from juvenile stem sesments of mung bean (V'~,na radiata). In particular, we have studied the influence of plant growth regulators.Induction of calli from young stem explants was very effective on MS inorganic salts supplemented with 0.5 ms/L 2,4-D and 1.0 n~ kinetin. In reseneratin 8 adventitious roots from callus tissues, we found that a combination of 0.75 mg/I. NAA, 1.5 mg/IL kinetin, and MS sails resulted in 20% efficiency. H~ examination showed that callus tissues oHSinated fromout-growths of the cambium rings through de-navo rneristematic activity. Those rings were localized outside the vascular cambium. AdventitJmJs tools that developed from root primordia originated from the center of the Callus masses. These primordia produced tracheid-like cells, which then became meristemoid cells for the cambium. Newly formed adventitious roots had the typical tetrarche aclinostele type. Park et al.Calli were induced from young stems 4 to 5 d after culturing in an MS medium containing 0.75 mg/L NAA and 1.50 mg/L kinelJn (Fig. 3A). The explants were fixed and sectioned every 12 h after culture. By that

“…This was found in regenerated shoot bud, which was similar to organogenesis in leaf-derived callus of black pepper (Sujatha et al 2003) and endospermderived callus of kiwifruit (Popielarska et al 2006). This tunica-corpus resembled bud meristem in Foeniculum vulgare callus (Anzidei et al 1996). Histological analysis of bud-like structure of coconut endosperm showed clearly that there were a meristematic layer with a dermal layer, cortex-like region and central vascular tissue.…”

Coconut is a very important plant for the livelihood of people in tropical countries. It is also used as an icon of tropical region. Coconut fruit is very heavy and can cause injuries if the fruit falls down and hits somebody who happens to be underneath a coconut tree. In order to avoid the accident, the coconut fruits have to be regularly cut off. Coconut tree originated from in vitro cultured endosperm is a triploid plant that produces seedless fruit (without endocarp). Coconut fruit without endocarp is not heavy. The objective of this study was to investigate plant regeneration of fresh and in vitro cultured coconut endosperms. The fresh and developed in vitro cultured coconut endosperms were observed using histological analysis. Solid endosperm of seven month-old postanthesis coconut from "Samoan Dwarf " cultivar was freshly picked up and cultured in vitro on modified Branton & Blake formula. Histological study of fresh coconut endosperm showed that the endosperm consisted of parenchyma cells, which were relatively uniform in shape and size, with some nuclei consisted of 1 -5 nucleoli. Three month-old calli of in vitro grown coconut endosperm in semi solid media showed that its cells varied in shape and size, characterized by high nucleus to cytoplasm ratio, high starch, protein and lipid contents which underwent many divisions. Seven month-old calli of in vitro grown coconut endosperm in liquid media showed embryogenic cells which resembled proembryos. Fourteen month-old bud-like structure of coconut endosperm in semi solid media showed a meristematic layer, tunica-corpus structure, cortex-like region and tracheids of xylem. These results indicated that the bud-like structure was an early stage of shoot bud formation in coconut endosperm. This is the first report of early stage of shoot bud formation occurring on coconut endosperm cultured in vitro.
