O uso de reguladores de crescimento na fase de germinação melhora o desempenho das plântulas, acelerando a velocidade de emergência e realçando o potencial das sementes de várias espécies, mesmo sob condições adversas. Este trabalho teve como objetivo avaliar a influência do ácido giberélico na atividade amilolítica e no vigor de sementes armazenadas de milho super doce. O experimento foi conduzido nos Laboratórios de Análise de Sementes do Departamento de Produção Vegetal/FCA e no Laboratório de Bioquímica de Plantas do Departamento de Química e Bioquímica/IB da Universidade Estadual Paulista (UNESP/Botucatu), entre os meses de julho e setembro de 2001, onde foram feitas as avaliações da qualidade fisiológica, através dos testes de germinação, vigor e... |

Several studies were carried out in order to improve the knowledge about the occurrence and activity of nitric oxide (NO) in plants. Thus, this review discusses some aspects related to NO in plants such as chemical properties, synthesis pathways, physiological effects, antioxidant action, signal transduction, interaction with plant hormones and gene expression. In the last years, many advances have been obtained regarding NO synthesis and its physiological effects in plants. However, the molecular mechanisms underlying its effects remain poorly understood. It is signalized that tight interplays among NO, Ca2+, cyclic ADP ribose (cADPR), and protein kinases need to be investigated in details. In addition, it has not yet been possible to identify a plant... |

Information on improved fall panicum cultivars and agronomical pratices is scarce because of the relatively small importance of this crop in Brazil. The present study aimed to evaluate levels of nitrogen sidedressing on plant development and biochemical characteristics of two fall panicum cultivars. The experiment was set up under plastic tunnel conditions in Botucatu, São Paulo, Brazil, with plants growing inside asbestos-cement boxes. The experimental design was a randomized block setup and treatments consisted of six levels of nitrogen fertilization (0, 40, 80, 120, 160, and 200 mg L-1) applied at the onset of tillering on two fall panicum cultivars (AL Mogi and AL Tibagi). The application of increasing levels of nitrogen to fall panicum plants... |
