Science teacher's discourse about reading
Inez Barcellos de Andrade,Isabel Martins
Investiga??es em Ensino de Ciências , 2006,
Abstract: In this research we start from the assumption that teachers act as mediators of reading practices in school and problematise their practices, meanings and representations of reading. We have investigated meanings constructed by a group of teachers of Physics, Chemistry and Biology, working at a federal technical school. Having French discourse analysis as our theoretical-methodological framework, we considered that meanings, concepts and conceptions of reading are built historically through discourses, which produce meanings that determine ideological practices. Our results show that, for that group of teachers, there were no opportunities during either initial training or on-going education for reflecting upon the role of reading in science teaching and learning. Moreover, there seems to be an association between the type of discourse and modes of reading, so that unique meanings are attributed to scientific texts and their reading are linked to search and assimilation of information.
Influência do tamanho da semente na emergência das plantulas de longan (Dimocarpos longan Lour)
Oliveira, Inez Vilar de Morais;Costa, Raquel Silva;Andrade, Renata Aparecida de;Martins, Antonio Baldo Geraldo;
Revista Brasileira de Fruticultura , 2005, DOI: 10.1590/S0100-29452005000100045
Abstract: with the objective to evaluate the percentage of seedlings emergence and the emergence velocity index (evi) of longan (dimocarpos longan lour) seeds, was carried out the present research, using plants that came from the germplasm bank of the department of vegetable production of the faculdade de ciências agrárias e veterinárias - unesp - campus of jaboticabal, s?o paulo state, brazil. immediately after the extraction, the seeds were washed, dryed and sowed in sand seed beds. the experimental delineation was entirely randomized, with three treatments, characterized by the size of the seeds: big, medium and small, determined by the medium weight of 50 seeds (in grams), being: 89; 80 and 65g respectively. the values of percentage of emergence were transformed in arc-sen square root (x / 100). the averages were compared by the test of tukey, with 5% of probability. it was not observed significantly difference to the evaluated parameters, being obtained the values of the percentage of emergence of 97 to 91% and evi of 0,651 to 0,680, showing that the size of the seed is not a factor to be considered for this specie.
Influence of the substrate in germination of lychee seeds
Andrade, Renata Aparecida de;Martins, Antonio Baldo Geraldo;Oliveira, Inez Vilar de Morais;
Revista Brasileira de Fruticultura , 2004, DOI: 10.1590/S0100-29452004000200049
Abstract: the lychee is, all over the world, considered as the "queen of the fruits" due to the delicacy of its appearance and flavor. although it was only recently that it started to have economical importance in brazil, the lychee is already calling the attention of numerous farmers, mainly those who cultivate citric fruits and/or sugarcane in the state of s?o paulo, due to the constant and at the same time growing necessity of finding new alternative crops. considering that the commercial cultivation of lychee plants in the field requires the previous obtainment of rootstocks viewing to reduce the genetic variability and the length of the juvenile period displayed by plants resulting directly from the seeds, finding ways to improve the germination performance of lychee seeds for the production of rootstock plants is of considerable economic importance. thus, the objective of this experiment was to test five substrates for the germination of lychee seeds: (1) vermiculite, (2) washed sand, (3) filter paper, (4) carbonized rice hull, and (5) sphagnum. the results showed that the period of time required by a lychee seed to germinate is a short one thus reinforcing the importance of providing a suitable substrate for the germination to take place. it was found that the substrates which apparently allowed the best combinations of water and oxygen availability for the seeds - washed sand and carbonized rice hull - were those leading to the fastest and highest germination values.
Influência da condi??o e período de armazenamento na germina??o de sementes de pitaya vermelha

Revista Brasileira de Fruticultura , 2005, DOI: 10.1590/S0100-29452005000100044
Abstract: the experiment was carried out in the department of vegetable production of the faculdade de ciências agrárias e veterinárias - campus of jaboticabal- s?o paulo state - brazil, using seeds that were extracted from ripe fruit, that were washed, drying in environmental condition during 24 hours and conditioned in paper bags, disposed according to the treatments: 3 storage conditions of the seeds: environmental; dry chamber (16-18oc e 60% ur) and cold chamber (10oc e 60-70% ur), and 4 storage periods: 7, 14, 21 and 28 days after the extraction of the seeds, besides of the seedling immediately of the extraction of the seeds. after these periods the seeds were conditioned in gerbox boxes, having as substrate filter of paper and maintained in a germination chamber with a constant temperature of 25oc. based on the results, it is possible to conclude that the seeds of red pitaya can be storage in cold chamber for until 28 days without damage in percentage of germination.
Influência da temperatura na germina??o de sementes de Annona Montana
Oliveira, Inez Vilar de Morais;Andrade, Renata Aparecida de;Martins, Antonio Baldo Geraldo;
Revista Brasileira de Fruticultura , 2005, DOI: 10.1590/S0100-29452005000200041
Abstract: with the objective to evaluate the influence of the temperature in percentage of germination and the germination velocity index (gvi) of seeds of annona montana, a potencial specie for a rootstock to the comercial varieties, were tested four temperatures (20, 25, 30 and 35oc). the research was carried in conditions of laboratory, in chamber of germination type bod using seeds of tree plants that came from the germplasm bank of the department of vegetable production of the faculdade de ciências agrárias e veterinárias unesp, campus of jaboticabal, s?o paulo state, brazil. the experimental delineation was entirely randomized, and four replications with ten seeds in each one. by the obtained results, was observed that to the parameter percentage of germination and for the gvi, the bigger values observed were for the seeds in temperature of 30oc (55% of germination and gvi = 0,153), following by the temperature of 25oc (25% of germination and gvi = 0,088). to the temperatures of 20 and 35oc were not observed occurrence of germination. the statistical analysis of the values of percentage of germination were transformed in arc sen, square root (x/100) and the averages were compared by the test of tukey, with 5% of probability.
