Biotic and abiotic factors, such as luminosity, temperature, air humidity, herbivory, can affect the establishment of reintroduced plants in natural habitats. This study evaluated effects these factors on survival growth Cattleya intermedia into a forest fragment South Brazil. Plants C. were obtained from vitro seed germination asymbiotic culture. Eighty-eight at both edge interior. with greater shoot heights number leaves pseudobulbs suffered more damage herbivores edge. There no...

Cattleya intermedia is an Atlantic Forest species endemic to Brazil that classed as vulnerable on the list of threatened species. In this study, C. plantlets were micropropagated in asymbiotic culture and influence different concentrations sucrose (15, 30, 45 60 g L-1, plus a zero medium) macronutrient salts (complete Murashige Skoog (MS) medium half MS (with half-strength macronutrients)) survival development was evaluated. all treatments 100% plantlet achieved. The integrated analysis...

Resumo A cultura in vitro é uma ferramenta eficiente para a propagação de plantas importância ecológica e econômica permite o entendimento acerca aspectos ecofisiológicos das espécies. Este estudo teve por objetivo avaliar influência diferentes concentrações macronutrientes sobre desenvolvimento sobrevivência ex plântulas Vriesea incurvata, visando à conservação desta bromélia epifítica endêmica da Floresta Atlântica. germinação foi avaliada aos 60 dias as foram cultivadas 180 em meio MS com...

Anathallis adenochila is a small epiphytic orchid, endemic to the Atlantic Forest in southern and southeastern regions of Brazil. Information on species scarce limited distribution occurrence data, with no reports about its development. In present study, plantlets were propagated vitro, influence different concentrations macronutrient salts sucrose survival development was assessed. The analysis performed complete Murashige Skoog (MS) medium half MS (with half-strength macronutrients)...

Vriesea incurvata is an epiphytic bromeliad of the Atlantic Forest with ornamental attributes that encourage extractivism. This study assessed influence sucrose (10, 30 and 60 g L-1) on survival development V. plantlets cultivated for 180 days MS medium acclimatizated 150 under controlled conditions. Survival 100% was recorded in all vitro treatments. Sucrose at concentration L-1 provided highest length aerial portion longest root, greatest number leaves roots, fresh mass lowest contents...

Bromeliaceae is restricted to the Neotropical region and has a high degree of endemism, which contributes increased biodiversity because diverse morphological characteristics individuals. In order develop an in vitro conservation technology obtain plants for reintroduction, seeds Vriesea flammea L.B.Sm. were collected, sterilized germinated culture medium. The obtained cultured 180 days MS medium with different concentrations mineral nutrients (25 50% nitrogenous salts macronutrients),...

Helionothrips errans (Williams) (Thysanoptera: Thripidae) is reported for the first time in Neotropics. This thrips breeds exclusively on Orchidaceae (Asparagales) leaves and has previously been found Australia, USA, Europe, southwestern Asia. We observed H. damaging of reintroduced Cattleya intermedia Graham ex Hook. plantlets, attacked individuals showed reduction height aerial portion average number per individual. Sumario e registrado pela primeira vez para os Neotropicos. A especie se...

This is the first study that report symbiosis in Cattleya, aiming to isolate and identify mycorrhizal fungi capable of promoting germination this orchid, evaluate development symbiotically propagated individuals. We compared seed percentage, growth index morphometric variables seedlings OMA medium with individuals were non-symbiotically MS medium. Fungi isolates identified by phylogenetic analysis eight nine efficient C. intermedia propagation as Tulasnella amonilioides. The mycobiont...

Abstract The traits of the bark host trees can influence distribution and development epiphytes. Bark samples were suspended in 10 20 mL distilled water for 1, 4 24 h, to evaluate pH determination methods. Myrcia brasiliensis, M. glabra Myrsine coriacea, three Cattleya intermedia had collected from trunk crown, evaluation pH, retention capacity thickness. Shoot height (cm) number roots C. grown on into crown species evaluated. Volume solvent suspension time influenced values. thickness...

Micropropagation of epiphytic bromeliads associated to translocation may act as an important tool for conservation, restauration or mitigation initiatives. Vriesea incurvata is tank-forming bromeliad endemic the Atlantic Forest, being species in gallery forest environments. Seeds V. were germinated vitro, and plants acclimatized translocated each two microhabitats (gallery interior) Forest fragment South Brazil that harbors few individuals species. The 152 (76 per microhabitat) monitored...

Despite Orchidaceae is a key component of the epiphytic flora tropical and subtropical forests, phenological studies this group are rare, mainly due to technical difficulties in observing epiphytes, reduced abundance wild specimens, evergreen characteristic these plants. We monitored shoot root production translocated young plants orchid Cattleya intermedia Graham at edge interior Atlantic Forest fragment, investigated their relationship with temperature, luminosity, photoperiod, rainfall...

Abstract Cattleya cernua is an epiphytic orchid native of the Atlantic Forest, Cerrado, Caatinga and Pampa. Aiming at development in vitro conservation technology, plants were micropropagated through asymbiotic culture influence different concentrations sucrose (10, 30, 60 90 g L-1) macronutrients (25, 50 100% MS) on survival was evaluated. Plant ranged between 47 100%. The interaction influenced plant development. aerial system higher MS medium combined with 30 or L-1 sucrose. number roots...
