Análise do risco da ocorrência de biotipos de plantas daninhas resistentes aos herbicidas
(1998) [Artículo de periódico]A análise do risco da ocorrência de biotipos de plantas daninhas resistentes aos herbicidas dispõe de fundamentos teóricos adequados, porém é limitada pela falta de mais informações genéticas das espécies daninhas. O risco ... -
Caracterização e influência de rizóbios isolados de alfafa na germinação e desenvolvimento inicial de plântulas de arroz
(2011) [Artículo de periódico]A inoculação de plantas leguminosas com rizóbios é um dos principais métodos biotecnológicos de utilização de micro-organismos em plantas visando à fixação biológica de nitrogênio na agricultura. No entanto, nos últimos ... -
Chromosome doubling in Paspalum notatum var. saure (cultivar Pensacola)
(2015) [Artículo de periódico]Paspalum notatum is one of the most important native grassland species of southern Brazil, and the main forage source for livestock. The native ecotypes are tetraploid and have apomictic reproduction, which prevents the ... -
Controle genético da resistência parcial à ferrugem da folha em aveia (Avena sativa L.)
(2008) [Artículo de periódico] -
Cytogenetic characterization of Angelonia integerrima Sprengel, a native species with ornamental potential
(2019) [Artículo de periódico]Angelonia integerrima Sprengel is a native species of the state of Mato Grosso do Sul and the Southern region (Paraná, Santa Catarina and Rio Grande do Sul) of Brazil, with features such as an unusual appearance and color ... -
Diverse genetic mechanisms underlie worldwide convergent rice feralization
(2020) [Artículo de periódico]Background: Worldwide feralization of crop species into agricultural weeds threatens global food security. Weedy rice is a feral form of rice that infests paddies worldwide and aggressively outcompetes cultivated varieties. ... -
Evaluation of total protein, peroxidase, and nutrients measured by pXRF for the determination of tissue rejuvenation / reinvigoration of Eucalyptus microcorys
(2023) [Artículo de periódico]Ontogenetic aging of tissues and the gradual decrease of adventitious rooting are known challenges for the clonal propagation of woody species, hampering clonal forestry programs. This study examined possible signatures ... -
Expression of genes related to soil flooding tolerance in soybeans
(2019) [Artículo de periódico]The flooded environment brings about injuries to soybeans that vary depending on the adaptation ability of the genotype. Oxygen deprivation promotes the induction of the expression of genes related to glycolysis and ... -
Gene expression : a review on methods for the study of defense-related gene differential expression in plants
(2013) [Artículo de periódico] -
Genetic analysis of the naked trait in panicles of hexaploid oat
(2014) [Artículo de periódico]The aim of this study was to estimate the number of genes that control the naked (hull-less) trait and the mode of expression of this characteristic in panicles of hexaploid white oat. Parents and the segregating population ... -
Genetic and cytogenetic structure of wild lemon grass (Elionurus muticus) populations
(2015) [Artículo de periódico]Elionurus muticus is a native aromatic grass from the Pampa biome that produces an essential oil that is rich in citral. Despite the importance of citral, few studies have examined this species. The aims of this work were ... -
Genetic and cytological diversity in cherry tree accessions ( Eugenia involucrata DC) in Rio Grande do Sul
(2016) [Artículo de periódico]This study aimed to evaluate the genetic and cytological diversity and stability of 35 cherry tree accessions collected in Rio Grande do Sul. We used 15 RAPD (Random Amplified Polymorphic DNA) molecular markers and performed ... -
Genetic assessment of seed yield-related traits in superior hybrids of Paspalum plicatulum × Paspalum guenoarum
(2019) [Artículo de periódico]This study aimed to estimate the genetic parameters, genetic correlations, genetic dissimilarity, and predicted gains with the selection of interspecific apomictic Paspalum plicatulum × Paspalum guenoarum hybrids in relation ... -
Genetic control of agronomic traits in an oat population of recombinant lines
(2010) [Artículo de periódico]Understanding the genetic control of phenotypic traits is essential to increase the efficiency of selection for adapted, high-yielding genotypes. The purpose of this study was to determine the genetic control of nine traits ... -
Genetic divergence among interspecific Paspalum hybrids based on seed production traits
(2017) [Artículo de periódico]The use of genetic divergence as a basis for identifying superior individuals, with greater heterozygosity, is important in view of the difficulty when selecting of dissimilar genotypes exhibiting high average for interest ... -
Genetic diversity assessed by microsatellite markers in the amphicarpic species Trifolium polymorphum Poir.
(2018) [Artículo de periódico]Trifolium polymorphum Poir. is an amphicarpic forage legume from southern Brazil, Uruguay, Argentina, Paraguay and Chile. Information on the genetic diversity of natural populations in natural grasslands in southern Brazil ... -
Genetics and identification of markers linked to multiflorous spikelet in hexaploid oat
(2016) [Artículo de periódico]The formation of naked grains is directly associated with the formation of multiflorous spikelets in oats. The objectives of this study were to determine the genetics of multiflorous spikelet and to identify molecular ... -
Genetic similarity in a hybrid population of 'Montenegrina' and 'King' mandarins
(2012) [Artículo de periódico]The objective of this work was to confirm the hybrids obtained in plants originated from the crossing between the mandarins Citrus deliciosa 'Montenegrina' and C. nobilis 'King', and to estimate the genetic similarity among ... -
