Abstract

NAKADA, Pâmela Gomes et al. Performance during storage of cucumber seeds under different methods of drying. Rev. bras. sementes [online]. 2010, vol.32, n.3, pp. 42-51. ISSN 0101-3122.  http://dx.doi.org/10.1590/S0101-31222010000300005.

The drying of seeds of cucumber is a compulsory stage in his improvement, as well as the storage to conquer competitive markets and better opportunities of prices. So the objective with this work valued the physiologic and biochemical performance during the drying and storage of seeds of cucumber. Cultivating used was the hybrid of cucumber Ômega marketed by the Agristar Ltda. The seeds were washed and dried at room temperature 25 ºC, 35 ºC and 45 ºC, following the storage in conditions ambient. The physiologic quality was valued through the germination test, first counting, conductivity electric and seedlings emergence. Also there was done sanitary analysis, evaluation of the activity of enzymes from the superoxide dismutase, catalase, esterase, lipoxigenase, isocitrato liase and LEA protein, and finally the analysis of images through ray X. The drying of seeds of cucumber, in ambient temperature, and to 35 ºC turns in seeds of better quality. LEA takes place reduction of the quality of the seeds and of the activity of the protein from six months of storage independent of the method of drying.
