1. Feasibility of the new method for orchid in vitro rooting using liquid and chemical sterilized culture medium under different sucrose concentration
Resumo A propagação in vitro de orquídeas é a única técnica comercial em larga escala para obtenção de plântulas saudáveis e de alta qualidade com origem clonal. O uso de novas tecnologias em sistemas de cultura de tecidos vegetais pode levar a aumentos de eficiência e redução de custos dos sistemas de micropropagação. O principal sistema de m

2. Tissue culture and biotechnological techniques applied to passion fruit with ornamental potential: an overview
Resumo O setor de flores ornamentais vem crescendo ao longo dos últimos anos em todo o mundo com potencial expansao. Entre as plantas ornamentais, espécies de Passiflora vem ganhando espaço no mercado, principalmente nos países da Europa e América do Norte. Contudo, o uso destas espécies na ornamentação ainda é pouco explorado. A inclusão da flor d

3. Advances and challenges on the in vitro production of secondary metabolites from medicinal plants
RESUMO A produção de metabólitos secundários de plantas medicinais, também chamados de Compostos Medicinais Derivados de Plantas (PDMC), vem ganhando importância na última década. Concomitante ao aumento do conhecimento sobre as propriedades farmacológicas destes compostos, as plantas da horticultura tornam-se a fonte de biomassa mais importante, su

4. In vitro propagation of alpinia cultivars in different light sources
Resumo A fonte de luz na cultura de tecidos muitas vezes é um dos fatores pontuais para a adequação da produção de plantas, para isso, vêm se utilizando os diodos emissores de luz (LEDs) no intuito de aumentar o crescimento e desenvolvimento das plantas propagadas in vitro. O objetivo do trabalho foi avaliar a propagação in vitro de cultivares de Alp

5. Detection of Somaclonal Variation in Micropropagated and Acclimatized Plantlets of Oryza sativa MRQ 74 from Stem Explants
RESUMO: No sistema de cultura de tecidos de plantas, o fornecimento excessivo de hormônios de crescimento vegetal pode inibir o crescimento e desenvolvimento dos regenerantes e, às vezes, induzir a variação somaclonal. Neste estudo, a concentração ideal de hormônios de crescimento para regeneração in vitro de Oryza sativa L. cv. MRQ 74 foi identific

6. Propagación del banano: técnicas tradicionales, nuevas tecnologías e innovaciones
Abstract The different propagation systems for the banana: conventional or by tissue culture are reviewed. Conventional propagation, mainly using suckers, whole rhizomes or bits are still in use for familiar plantings or in farms for local markets in many tropical countries, while vitroplants are the rule in modern commercial banana cultivation. After exami

7. Bioprospecting and selection of growth-promoting bacteria for Cymbidium sp. orchids
ABSTRACT: Inoculants containing bacteria which promote growth in plants can increase productivity and both the economic and the environmental cost in plant crop systems. Similarly, in the flower and ornamental plant sector, the use of diazotrophic bacteria is a promising approach for improving orchid propagation from tissue culture to the ex vitro environmen

8. Gene transfer utilizing pollen-tubes of Albuca nelsonii and Tulbaghia violacea
Abstract Developing a tissue culture-independent genetic transformation system would be an interesting technique for gene transfer in valuable medicinal and horticultural plants. Efficient gene delivery (Agrobacterium tumefaciens strain LBA 4404: harbouring PBI121 plasmid) was achieved with Km-resistant pollen grains (pollen tube technique) and were found to

9. Morpho-anatomical study of Stevia rebaudiana roots grown in vitro and in vivo
ABSTRACT Stevia rebaudiana (Bertoni) Bertoni, Asteraceae, is used as a food additive because its leaves are a source of steviol glycosides. There are examples of tissue culture based on micropropagation and phytochemical production of S. rebaudiana leaves but there are few studies on adventitious root culture of S. rebaudiana. More than 90% of the plants use

10. Tissue culture efficiency of wheat species with different genomic formulas
Abstract Ancient wheats are increasingly considered as valuable resources for genes of interest which could be analyzed and introduced into cultivated varieties by genetic engineering technologies. The first stage of biotechnological crop improvement consists of successful in vitro plant regeneration. Twelve wheat germplasms with different genomic formulas (

11. Tissue culture of ornamental cacti
Cacti species are plants that are well adapted to growing in arid and semiarid regions where the main problem is water availability. Cacti have developed a series of adaptations to cope with water scarcity, such as reduced leaf surface via morphological modifications including spines, cereous cuticles, extended root systems and stem tissue modifications to i
