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...

Matthiola incana (Brassicaceae) is an important ornamental plant, which is used as cut flower, pot plant, and landscape. Traditionally, it is propagated via seeds, but interest is given in vegetative propagation of parental lines as well as superior single plants. Micropropagation by organogenesis is an efficient in vitro propagation method for Matthiola incana. Starting from seeds, apical bud ...

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...

Abstract. Harahap F, Nusyirwan N, Afiva A, Prasetya E, Suriani C, Hasibuan RFM, Poerwanto R. 2022. Short Communication: Genetic similarity analysis of in vitro cultivated pineapple (Ananas comosus) from Sipahutar, North Sumatra, Indonesia using ISSR markers. Biodiversitas 23: 5623-5628. Sipahutar Indonesia, is considered difficult to breed, resulting a lack seed availability. However, tissue cu...

To know what a physio-chemical situation in the micro-propagating banana variety Basrai under saline conditions, an experiment was conducted. In vitro plantlets were developed by culturing meristematic stem tips (explant) for 3 weeks on organogenesis (8.0 μM BA; 10.0 μM IAA; 3.0 g l phytagel), 3 weeks on shoot induction (15.0 μM BA; 1.0 g l phytagel) and 4 weeks on shoot multiplication (10.0 μM...

A rapid in vitro propagation system leading to the formation of shoots, calli, roots, cell suspensions and plantlets was developed for the Andean medicinal plant Fabiana imbricata (Solanaceae). Massive propagation of shoots and roots was achieved by the temporary immersion system (TIS), morphogenesis and maintenance of cell suspensions by standard in vitro culture techniques. Oleanolic acid (OA...

A non-destructive cultivation system was developed to study the dynamics of phosphorus (Pi) uptake by mycorrhizal and non-mycorrhizal maize plantlets. The system consisted of a plant container connected via silicon tubes to a glass bottle containing a nutrient solution supplemented with Pi. The nutrient solution is pumped with a peristaltic pump to the upper part of the container via the silico...

An efficient method was developed for plant regeneration and establishment from alginate encapsulated synthetic seeds of Rauvolfia serpentina. Synthetic seeds were produced using in vitro proliferated microshoots upon complexation of 3% sodium alginate prepared in Llyod and McCown woody plant medium (WPM) and 100 mM calcium chloride. Re-growth ability of encapsulated nodal segments was evaluate...
