| Vários procedimentos são utilizados para avaliar o potencial fisiológico de sementes, sendo fundamental a utilização daqueles que reflitam melhor o desempenho em campo. A pesquisa teve como objetivo avaliar o potencial fisiológico de sementes de soja por meio de testes de avaliação rápida, de vigor, de emergência de plântulas em campo e análise computadorizada de imagens (SVIS®), procurando identificar o procedimento mais eficiente na separação de lotes. Cinco lotes das cultivares BRS Valiosa RR e CD 208 foram avaliados em duas épocas (antes e após armazenamento) pelos testes de germinação, de avaliação rápida (embebição em água e pH do exsudato), de vigor (envelhecimento acelerado e condutividade elétrica), de emergência de plântulas em campo e análise... |

| Nowadays, image analysis is one of the most modern tools in evaluating physiological potential of seeds. This study aimed at verifying the efficiency of the seedling imaging analysis to assess physiological potential of wheat seeds. The seeds of wheat, cultivars IAC 370 and IAC 380, each of which represented by five different lots, were stored during four months under natural environmental conditions of temperature (T) and relative humidity (RH), in municipality of Piracicaba, Stated of São Paulo, Brazil. For this, bimonthly assessments were performed to quantify moisture content and physiological potential of seeds by means of tests of: germination, first count, accelerated aging, electrical conductivity, seedling emergence, and computerized analysis of... |

| ABSTRACT Identifying fast and efficient tests to evaluate the vigor of forage grass seed lots is desirable in the quality control programs of the companies in this sector. Thus, the objective was to evaluate the efficiency of vigor tests on the physiological quality of seeds of Panicum maximum, cv. Mombasa, for the differentiation of lots and prediction of seedling emergence in the field. Nineteen seed lots were subjected to evaluations of moisture content, germination, first count, germination speed index, seedling emergence in sand, first count of seedling emergence in sand, seedling root and shoot lengths, seedling emergence in the field and computerized analysis of seedling images obtained through SVIS® software. The experimental design was completely... |
