Manejo sustentado do palmiteiro (Euterpe edulis M.) na pequena propriedade cata...
Conte, Rudimar; dos Reis, Maurício Sedrez; Guerra, Miguel Pedro; Nodari, Rubens Onofre; Fantini, Alfredo CelsoEste trabalho teve por objetivo apresentar indicadores técnicos e econômicos para o manejo sustentado do palmiteiro (Euterpe edulis M.) no Estado de Santa Catarina, a partir de uma unidade demonstrativa de manejo implantada na Floresta Nacional de Ibirama, SC – Flona de Ibirama, SC.
DNA methylation patterns and karyotype analysis of off-type and normal phenotyp...
Cristofolini, Caroline; Vieira, Leila do Nascimento; Fraga, Hugo Pacheco de Freitas; Costa, Itayguara Ribeiro da; Guerra, Miguel Pedro; Pescador, RoseteAcca sellowiana is a native species to the southern region of Brazil, with secondary dispersion in Uruguay northeast. The potentially economic interest of this species motivated many fundamental and applied researches, such as micropropagation protocols development, including somatic embryogenesis (SE). Previous studies have reported the high frequency of off-type somatic embryos in A. sellowiana SE and low con...
Two new Brazilian feijoa cultivars: SCS 414-Mattos and SCS 415-Nonante
Ducroquet, Jean-Pierre Henri J.; Nunes, Eduardo da Costa; Guerra, Miguel Pedro; Nodari, Rubens OnofreContinuing its breeding program of feijoa (Acca selowiana), one of the most promising commercialnative fruit-tree of Southern Brazil, Epagri is launching two new cultivars, SCS 414-Mattos and SCS 415-Nonante, with the intention of extending and improving the flow of feijoa supply to the market. The peak of harvesting forMattos cultivar fits between Alcantara and Helena, two cultivars launched in 2007, while ‘No...
Physiologic evaluation of the seeds stored in Epagri germplasm collections
Diola, Valdir; Vidor, Mário Angelo; Guerra, Miguel PedroThe physiological state of several species maintained at Epagri’s germplasm collections was studied by means of viability and germination tests, and vigor index. Species of Phaseolus vulgaris, Allium cepa, Oriza sativa, Paspalum dilatatum, Bromus auleticus, Trifolium repens and Adesmia tristis had ten accessions sampledeach one. By the statistical analysis it was observed that the evaluation methods were ade...
Embryonal Masses Induced at High Temperatures in Aleppo Pine: Cytokinin Profile...
Pereira, Cátia; Castander-Olarieta, Ander; Montalbán, Itziar A.; Pěnčík, Aleš; Petřík, Ivan; Pavlović, Iva; De Medeiros Oliveira, ElianaAleppo pine (Pinus halepensis Mill.), a native species of the Mediterranean region, has been suggested as a species that when introduced in degraded areas could facilitate the long-term colonization and expansion of late-successional species. Due to climate changes, plants need to withstand extreme environmental conditions through adaptation and changings in developmental pathways. Among other paths, plants und...
Somatic embryogenesis in peach palm using the thin cell layer technique: Induct...
Steinmacher, Douglas André; Krohn, N. G.; Dantas, A. C.M.; Stefenon, Valdir Marcos; Clement, Charles Roland; Guerra, Miguel Pedro• Background and Aims: The thin cell layer (TCL) technique is based on the use of very small explants and has allowed enhanced in vitro morphogenesis in several plant species. The present study evaluated the TCL technique as a procedure for somatic embryo production and plantlet regeneration of peach palm. • Methods: TCL explants from different positions in the shoot apex and leaf sheath of peach palm were cult...
Dynamics of proteins, carbohydrates and global DNA methylation patterns during ...
Corredor, Jenny; De Conti, Daniela; Guerra, Miguel Pedro; Dal Vesco, Lirio Luiz; Pescador, RoseteTissue culture techniques have been employed for bromeliad mass propagation by means of the morphogenetic route of nodular cluster cultures (NCs). This study aimed to assess protein, carbohydrate and global DNA methylation (GDM) level dynamics during NCs induction from Vriesea reitzii seeds. Seeds were inoculated into Murashige and Skoog (MS) liquid medium supplemented with 4 µM α-naphthaleneacetic acid (NAA) t...
Phylogenetic inference and SSR characterization of tropical woody bamboos tribe...
Rogalski, Marcelo; Vieira, Leila do Nascimento; Anjo, Karina Goulart dos; Faoro, Helisson; Fraga, Hugo Pacheco de Freitas; Greco, Thiago MachadoThe complete plastome sequencing is an efficient option for increasing phylogenetic resolution and evolutionary studies, as well as may greatly facilitate the use of plastid DNA markers in plant population genetic studies. Merostachys and Guadua stand out as the most common and the highest potential utilization bamboos indigenous of Brazil. Here, we sequenced the complete plastome sequences of the Brazilian Gua...
The Linum usitatissimum L. plastome reveals atypical structural evolution, new ...
Santana Lopes, Amanda de; Pacheco, Túlio Gomes; Santos, Karla Gasparini dos; Vieira, Leila do Nascimento; Guerra, Miguel Pedro; Nodari, Rubens OnofreFlax (Linum usitatissimum L.) is an economically important crop used as food, feed, and industrial feedstock. It belongs to the Linaceae family, which is noted by high morphological and ecological diversity. Here, we reported the complete sequence of flax plastome, the first species within Linaceae family to have the plastome sequenced, assembled and characterized in detail. The plastome of flax is a circular D...
Genetic, evolutionary and phylogenetic aspects of the plastome of annatto (Bixa...
Pacheco, Túlio Gomes; Lopes, Amanda de Santana; Viana, Gélia Dinah Monteiro; Silva, Odyone Nascimento da; Silva, Gleyson Morais da; Rogalski, MarceloAnnatto (Bixa orellana L.) is a native species of tropical Americas with center of origin in Brazilian Amazonia. Its seeds accumulate the apocarotenoids, bixin and norbixin, which are only found in high content in this species. The seeds of B. orellana are commercially valued by the food industry because its dyes replace synthetic ones from the market due to potential carcinogenic risks. The increasing consumpt...
