Novel species of fungi described in this study include those from various countries as follows: Argentina , Neocamarosporium halophilum leaf spots Atriplex undulata . Australia Aschersonia merianiae on scale insect ( Coccoidea ), Curvularia huamulaniae isolated air, Hevansia mainiae dead spider, Ophiocordyceps poecilometigena Poecilometis sp. Bolivia Lecanora menthoides sandstone, open semi-desert montane areas, Sticta monlueckiorum corticolous a forest, Trichonectria epimegalosporae...
The induction and subsequent regeneration of protocorm-like bodies (PLB) is the most common morphogenetic pathway for orchid micropropagation. plants from PLB can be a bottleneck some species due to asynchronicity. Genetic fidelity another issue, cytogenetic stability regenerated plantlets deserves special attention occurrence endopolyploidy in orchids. In present work, we defined optimal conditions plant Cattleya tigrina, threatened Brazilian Atlantic Rain Forest. We estimated optimum...
Improvements of in vitro culture protocols are essential to increase productivity order ensure their practical application commercial laboratories. The aim the present work was evaluate influence light sources different wavelengths combination with natural ventilation atmosphere (NV) all steps micropropagation, from seed germination and protocorm development (SGS) plantlet growth (PGS), as well for ex acclimatization. Additionally, we compared use a temporary immersion bioreactor...
Gaylussacia brasiliensis is a bush from the Ericaceae family native to South America. It considered an underutilized fruit species, despite its importance as food source, medicinal plant, and forage for fauna. In Florianópolis island, south of Brazil, it occurs in sand deposits between Atlantic Ocean mountain chains Rain Forest, vegetation type called "Restinga", harsh environment where plants are exposed stressful conditions. Constand winds, high solar radiation, saltwater sprays, low...
ABSTRACT The bamboo productive chain is still incipient in Brazil, and the low supply of plantlets due to low-efficient conventional propagation methods presents a significant bottleneck its development. This study aimed establish micropropagation protocol for Guadua chacoensis. Explants from donor plants cultivated under controlled environment showed less contamination, if compared explants grown field. contamination rate was even lower when 2 mL L-1 Plant Preservative Mixture (PPM™) were...
The asymbiotic technique of orchid seeds germination is an important method mass production seedlings. Studies on the best culture conditions for each species are to obtain seedlings in less time and at lower costs. Current analysis evaluates different consistencies medium, saline formulations rate further development protocorms Epidendrum fulgens. After 45 days were classified into three categories development. liquid formulation Murashige Skoog (1962) (MS) provided highest (83.5%), Knudson...
<title>Abstract</title> The maintenance of forest formations under a scenario climatic changes and unsustainable anthropic use natural resources is vital for the future mankind. In this context, there rising agreement that underutilized crops may be important production food, as they tend to more adapted stressful conditions than domesticated crops.<italic>Eugenia uniflora</italic>L. (Myrtaceae) key species in different with ecological, economical, medicinal importance. present work aimed at...
This research aimed to study how exposing somatic embryos of Araucaria angustifolia cold temperatures in vitro could enhance embryogenesis. The were induced from immature zygotic embryos, grown for 120 days, and then subjected 4.5°C 0, 2, 4, 8, or 16 days. After the treatment, embryogenic cultures returned 25±2°C 20 days examined using light microscopy cytochemistry. It was found that at PEM III stage did not show further development, growth masses negatively affected longer-duration...
Abstract Bamboos are an important worldwide non-timber forest product with current rising interest due to their environmentally friendly applications. Besides the consolidated uses of sweet shoots and culms for structural uses, Dendrocalamus asper is imposing ornamental bamboo horticulture. The present work aimed establish in vitro calli culture plant regeneration through somatic embryogenesis starting from young inflorescences giant bamboo, D. . Pre-anthesis were collected, disinfested,...
The intense exploitation of coal deposits in Southern Brazil has caused severe degradation problems extensive areas. In order to recover such areas, the use revegetation with species adapted disturbed environments and capacity establish mutual relationships microorganisms have been great value. objective this study is characterize plant-root symbioses two grass-legume (Calopogonium mucunoides Brachiaria decumbens Vicia sativa decumbens) consortia inoculated soil Carboniferous Basin state...
Abstract The induction and regeneration of protocorm-like bodies (PLBs) is a morphogenetic pathway widely used for orchid micropropagation. As endopolyploidy, i.e., the coexistence cells with different ploidy levels, common feature in tissues, natural question arises when using somatic tissues as explants micropropagation: does endopolyploidy affect cytogenetic stability regenerated plantlets? To answer this question, Epidendrum fulgens was model plant, flow cytometry (FC) to analyze...
