Cecropia glaziovii is a tree with used in Brazilian popular medicine. Methods allowing the clonal propagation of this species are of great interest for superior genotype multiplication and perpetuation. For this reason, we examined the effect of different culture media and different types of explants on adventitious shoot regeneration from callus and buds of C. glaziovii. Leaves, petioles and s...

strawberry is a valuable, nutritious, and economically important fruit all over the world including bangladesh. therefore, there is a demand to develop a suitable variety of strawberry. for this purpose, leaf explants from in vitro grown strawberry plantlets were cultured onto ms medium supplemented with different concentrations and combinations of 2,4-d, naa and ba for callus induction. the mo...

To achieve large-scale low-cost ex vitro acclimatization of Siberian ginseng plants, heart- and torpedo-shaped secondary somatic embryos (SEs) induced from germinated SEs on agar medium were collected and then inoculated to 10-l bubble column bioreactor, respectively. For plantlet conversion, inoculation of torpedo-shaped secondary SEs was more effective than heart-shaped SEs. TS2 (culture of t...

Cattleya intermedia is an Atlantic Forest species endemic to Brazil that is classed as vulnerable on the list of threatened species. In this study, C. intermedia plantlets were micropropagated in an asymbiotic culture and the influence of different concentrations of sucrose (15, 30, 45 and 60 g L-1, plus a zero sucrose medium) and macronutrient salts (complete Murashige and Skoog (MS) medium an...

Physiological characteristics of in vitro and field cultivated Leucojum aestivum l. Plants stanilova m. summary. A living collection of Leucojum aestivum L. (Amaryllidaceae) was established at the Institute of Botany, Sofia, in 2001. In vitro cultures originating from a single mother bulb have been maintained since 2003 on MS-based agar-solidified medium supplemented with 30 g L-1 sucrose, 2 mg...

Somatic embryogenesis is one of good examples of the basic research for plant embryo development as well as an important technique for plant biotechnology such as medicinally important plants. Single embryos develop into normal plantlets with shoots and roots. Therefore, direct single embryogenesis derived from single cells is highly important for normal plant regeneration. Here we demonstrate ...

Hairy root cultures of Mitragyna speciosa were established by infection of Agrobacterium rhizogenes ATCC 15834 and maintained in McCown woody plant medium (WPM) supplemented with 0.5 mg/1 naphthaleneacetic acid. The hairy roots were identified for the rooting genes loci of rolA and rolB by polymerase chain reaction. For studying the secondary metabolite production, the n-hexane extract of the h...

In this study, several methods have been used to facilitate shoot formation from nodal explants of local almond ecotypes known as “Beldi” grown in Eastern Morocco. Nodal segments divers old genotypes were cultured on various concentrations auxin (indole-3-butyric acid (IBA)) and cytokinins (6-benzyl-aminopurine (BAP), thidiazuron (TDZ), kinetin (KIN)) added two different media (Murashige Skoog ...
