38. 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

39. Asymbiotic culture of Cattleya intermedia Graham (Orchidaceae): the influence of macronutrient salts and sucrose concentrations on survival and development of plantlets
ABSTRACTCattleya intermediais 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

40. 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)

41. 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

42. An efficient system for in vitro propagation of Bouchea fluminensis (Vell.) Mold. (Verbenaceae)
This study aimed to establish and propagate in vitro plants of Bouchea fluminensis, a medicinal species known in Brazil as gervão-falso ("false verbena"), evaluating the influences of different growth regulators on in vitro multiplication and rooting stages, as well as examining ex vitro acclimatization of rooted plants. Explants were established on Murashi

43. In vitro micropropagation of Stevia rebaudiana Bertoni in Malaysia
Stevia rebaudiana Bertoni is a medicinal plants and commercially use as non-caloric sweetener for diabetic patient. In the present study, a protocol was developed for in vitro micropropagation using 6-benzylamino purine (BAP) and Kinetin (Kn) for the formation of multiple shoot proliferation and Indole-3-acetic acid (IAA), Indole-3-butyric acid (IBA) and 1-N

44. Progress in micropropagation of Passifloraspp. to produce medicinal plants: a mini-review
Micropropagation of Passiflora species and its hybrids may play an important role in the production of healthy and disease-free plants which can be a source of medicinal herbal products, nutritional fruits and ornamental flowers. The rapid multiplication of elite plants to obtain pharmacognostic material, containing valuable flavonoid C-glycosides, is possib

45. Técnicas para otimização da multiplicação in vitro de brotações de Eucalyptus citriodora (Hook) K.D. Hill & L.A.S. Johnson / Optimization techniques for shoots in vitro multiplication of Eucalyptus citriodora (Hook) KDHill & LASJohnson
Pelas qualidades silviculturais e da madeira, o Eucalyptus citriodora apresenta-se como uma excelente espécie para usos múltiplos, destacando-se a extração de óleo essencial para indústria de perfumaria e desinfetantes. Entre as espécies de eucalipto é a que apresenta madeira de alta densidade, dependendo das condições edafoclimáticas e procedênc

46. Métodos para resgate, conservação e multiplação em larga escala de matrizes de Eucalyptus benthamii Maiden &Cambage / Methods for rescue, conservation and multiplication of matrices Eucalyptus benthamii Maiden &Cambege
The E. benthamii presents a great aptitude for cultivation in Brazil, especially in cold climates and with frequent frosts, this is due to your west of Sydney origin in Australia, where temperatures are very low, with frosts. Taking into account their optimal silvicultural performance, selected genotypes will certainly represent an excellent alternative for

47. Estudo para o estabelecimento de uma nova estratégia de clonagem in vitro de Cattleya e Cymbidium (Orchidaceae) por meio da utilização de gemas laterais de caules estiolados / Study to develop a new strategy to in vitro propagation of Cattleya and Cymbidium (Orchidaceae) using the lateral buds of etiolated shoot
Catasetum fimbriatum (Morren) Lindl. é uma orquídea estudada no Laboratório de Fisiologia Vegetal do IBUSP desde 1990. As plantas deste gênero, quando incubadas in vitro no escuro, apresentam crescimento contínuo do caule na ausência de qualquer regulador de crescimento. Quando as gemas laterais dos caules estiolados são isoladas e incubadas na presen

48. Aspectos morfofisiológicos na clonagem de Eucalyptus benthamii / Morphophysiological aspects in the cloning of Eucalyptus benthamii
Dentre as poucas espécies de Eucalyptus que apresentam aptidão ao cultivo em regiões de baixas temperaturas e a geadas frequentes, destacam-se genótipos de Eucalyptus benthamii que representam opções para futuros plantios florestais em diferentes regiões brasileiras. Porém, existem poucas informações quanto a obtenção de mudas clonais, e se focar
