13. Micropropagation and Cellular Behaviour Changes During in vitro Flowering of Impatiens balsamina
RESUMO: Neste estudo, a micropropagação de Impatiens balsamina foi estabelecida a partir de explantes de caule e parte aérea. Os efeitos do GA3 e da glutationa na morfogênese dessa espécie também foram investigados, de modo a induzir o florescimento in vitro. Verificou-se que a melhor regeneração in vitro de plantas foi obtida em meio MS adicionado c

14. Micropropagation, plantlets production estimation and ISSR marker-based genetic fidelity analysis of Guadua magna and G. angustifólia
RESUMO Os bambus Guadua magna e G. angustifolia têm sido propagados vegetativamente quase que exclusivamente por técnicas convencionais de propagação. Objetivou-se micropropagar, estimar a produção de mudas e analisar a fidelidade genética de G. magna e G. angustifolia por marcadores moleculares ISSR. Plantas matrizes de ambas as espécies foram culti

15. In vitro establishment of Bambusa oldhamii Munro from field-grown matrices and molecular identification of endophytic bactéria
RESUMO Na micropropagação de plantas, a etapa de estabelecimento é dificultada pela presença de micro-organismos em tecidos oriundos de matrizes do campo, especialmente para bambu. Objetivou-se estabelecer um protocolo eficiente de assepsia de explantes de Bambusa oldhamii oriundos de plantas em campo e efetuar a identificação molecular de um possível

16. Height and number of shoots on the survival and development of micropropagated bamboo plantlets during pre-acclimatization
RESUMO Durante a multiplicação in vitro de bambu, é rotineiro ocorrer a formação de agregados de brotos. Uma vez individualizados, eles podem render maior número de mudas do que se plantados agrupados. Objetivou-se avaliar o efeito da relação entre a altura e o número de brotos iniciais em mudas de bambu micropropagadas na sobrevivência e desenvolv

17. IN VITRO DEVELOPMENT OF YELLOW LAPACHO (BIGNONIACEAE) USING HIGH-POWER LIGHT EMITTING DIODE
RESUMO Handroanthus ochraceus (ipê-do-cerrado) é uma árvore medicinal, ornamentais e um recurso de madeira que pode ser propagada por cultura in vitro. Os métodos convencionais de propagaçao usam iluminação fluorescente (FL) e recentemente os diodos emissores de luz (LEDs). Este trabalho avalia os efeitos do FL e do LED de alta potência (HP-LED) na p

18. Morpho-physiological changes in Billbergia zebrina due to the use of silicates in vitro
Abstract The use of silicon in Billbergia zebrina cultivation in vitro is an alternative for optimizing micropropagation of this important ornamental plant species. The objective of the present study was to evaluate the growth and anatomical and physiological alterations in Billbergia zebrina (Herbert) Lindley plants as a function of different sources and co

19. Biotic Contamination and Possible Ways of Sterilization: A Review with Reference to Bamboo Micropropagation.
ABSTRACT Multipurpose use of bamboo in rural life makes it as poor man’s timber in Asian countries. Deforestation and industrialization leads to destruction of natural forest. To replenish, a rapid plantation of bamboo could be one of the possible solutions. Bamboo is propagated mainly by vegetative methods though it is not suitable for large scale plantat

20. Micropropagation of Cyrtopodium paludicolum (Orchidaceae) from root tip explants
Abstract An efficient protocol for in vitro plant propagation of Cyrtopodium paludicolum has been developed using root tips dissected from well-developed seedlings. Root tips were cultured on Knudson medium supplemented with α-naphthaleneacetic acid (NAA), and/or thidiazuron (TDZ). TDZ did not induce protocorm-like bodies (PLBs) in the NAA absence, indicati

21. 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

22. In vitro callus induction and micropropagation of Thymus persicus (Lamiaceae), an endangered medicinal plant
Abstract This is the first attempt towards an efficient regeneration protocol for an endangered and valuable medicinal plant, Thymus persicus using in vitro callus induction and indirect organogenesis. Callus induction was performed on MS medium supplemented with different concentrations of NAA and 2,4-D, alone or in combination with BAP and KN. Maximum cal

23. Cultivable endophytic bacteria from leaf bases of Agave tequilana and their role as plant growth promoters
Agave tequilana Weber var. 'Azul' is grown for the production of tequila, inulin and syrup. Diverse bacteria inhabit plant tissues and play a crucial role for plant health and growth. In this study culturable endophytic bacteria were extracted from leaf bases of 100 healthy Agave tequilana plants. In plant tissue bacteria occurred at mean population densitie

24. Optimal culture conditions for the initial development of Ilex paraguariensis A.St.-Hil. explants
In the state of Rio Grande do Sul, Brazil, yerba mate (Ilex paraguariensis A. St.-Hil.) is an economically and culturally important species. Because of the difficulty in obtaining plantlets from seeds, micropropagation has emerged as an alternative that could increase production. This work aimed to evaluate the effect that treatment with 6-benzyladenine (BA)
