The basic culture medium comprised the saline formulation MS To different types and combinations of PGR. Regeneration of adventitious shoots from seeds of V. Current study establishes a system of NC induction and Knowledge, the induction and development of NC from seeds has not yetīeen reported. VESCO GUERRA, 2010 RECH FILHO et al., 2009). However, the induction of NC inīromeliads is mainly based on leaf segments (ALVES et al., 2006 DAL (2011) reported the induction of NCįrom the nodal segments of B. Organs which induce the formation of callus similar to the NC in Aechmeaįasciata (HUANG et al., 2011a) and in Guzmania "Hilda" (HUANGĮt al., 2011b). The multiple productions of adventitious shoots under adequate growthĭifferent strategies are employed for the induction of NC inīromeliads, among which may be mentioned the use of floral segment The high competence of the morphogenetic system in vitro culminates in NodularĬultures are defined as groups or conglomerates of organogenic nodules They are regenerative in vitro systems based on morphogenetic patternsĪssociated with the induction of nodular culture (NC) (ALVES et al.,Ģ006 DAL VESCO GUERRA, 2010 RECH FILHO et al., 2009). philippocoburguii (DROSTE et al., 2005) andīillbergia zebrina (DAL VESCO et al., 2011). paludosa (ALVES GUERRA, 2001),ĭyckia distachia (POMPELLI et al., 2005), V. Several species of bromeliads native to the State of Santa Catarina,īrazil, such as V. Threatened species (GUERRA DAL VESCO, 2010), they have been applied to Since tissue culture techniques are a conservation strategy for Populations extremely reduced (KLEIN, 1990 LEME COSTA, 1991). The species is highly vulnerable because the AraucariaĪngustifolia, its primary epiphyte habitat, has had its natural Rainforest, distributed in the three southern states of Brazil atĪltitudes ranging between 7 m, within the domains of theĪraucaria Forest. Vriesea reitzii Leme and Costa (Figure 1A) is native to the Atlantic Throughout the Caribbean (SMITH DOWNS, 1977). Varieties and forms (LUTHER, 2008), distributed in the Americas and The genus Vriesea comprises 261 species and 44 (LUTHER, 2008), among which more than 50% of the species are epiphytes The Bromeliaceous family has more than 3.172 species and subspecies (ARANDA-PERES RODRIGUEZ, 2006 MARTINELLI et al., 2008). Ornamental and landscape value, or pharmacological interest Threats against this group come from the fragmentation of the forestĮcosystem and from the illegal extraction of plants due to their high Supporting the maintenance of diversity through adaptations andĮnvironment specializations (BENZING, 2000 MARTINELLI, 2000). Microhabitats formed by bromeliads contribute towards the stability ofįorest ecosystem in establishing an interaction with several species, Specific and generic diversity (MARTINELLI et al., 2008). This biome and belong to taxonomic groups with great richness and high On Earth, featuring a combination of endemism and critical threat The Atlantic Rainforest is one of the 25 hotspots of biodiversity APA style: In vitro propagation of Vriesea reitzii, a native epiphyte bromeliad from the Atlantic rainforest/Propagacao in vitro de Vriesea reitzii, uma bromelia epifita nativa da Mata Atlantica.In vitro propagation of Vriesea reitzii, a native epiphyte bromeliad from the Atlantic rainforest/Propagacao in vitro de Vriesea reitzii, uma bromelia epifita nativa da Mata Atlantica."

The Free Library.Sphericity was similar for both soils, with greater emphasis on pore classes with a diameter 15%). The soil classes differed in 3D pore characteristics, and this aspect may be important in the characterisation of causes of pore variability. ![]() The largest number (>4000) and volume (☓0 mm 3) of pores was found in the RL. The pores detected were different between the Latosols studied, mainly at 0.20–0.34 m depth. ![]() Greater spatial variability occurred in the horizontal direction of the 3D image, a novel finding in this area of research. The visualisation and quantification of pore size distribution by data mining and spatial variability by semi-variogams were investigated in 3D images with 60-µm spatial resolution generated by X-ray CT scan (EVS/GE MS8x-130) in soil core samples collected at different depths of a kaolinitic Red-Yellow Latosol (RYL) and a gibbsitic Red Latosol (RL) from Brazil. The aim of this study was to evaluate the spatial and morphological configuration of the pore space in 3D images of Latosols with different mineralogy under a conservation tillage system in a coffee crop area.
