The seeds of a sesame crop contain approximately 50% oil content, one of the main reasons for their cultivation. However, information regarding methodologies for the assessment of quality seeds of this culture are scarce. Therefore, the objective of this study was to adapt the methods of accelerated ageing tests for sesame seeds and investigate changes in the behaviour of isoenzymes. The physiological characterization of the seeds and electrophoretic analysis of the isoenzymes superoxide dismutase, esterase, catalase, alcohol dehydrogenase, malate dehydrogenase and isocitrate lyase were also performed. For the accelerated ageing test, the seeds were subjected to the traditional method, with a saturated NaCl solution, at ageing times of 0, 24, 48, 72, and...

The objective of this study was to evaluate gene expression related to water deficit tolerance in maize lines. For this, lines previously classified as tolerant (91-T and 32-T) and non-tolerant (24-NT and 57-NT) to water deficit were used. The seeds of the four lines were evaluated for emergence and emergence speed index, and the seedlings were evaluated for root and shoot length under two conditions of water availability (70 and 10% substrate water retention capacity). In transcript analysis, the expression of several genes associated with water deficit tolerance, ZmDBP3, ZmALDH9, ZmAN13, and ZmDREB2A, was evaluated by qRT-PCR for the 91-T and 57-NT lines. It can be concluded that soil water deficiency did not reduce root development. However, the shoot...

‘Desiccation tolerance of Rhamnidium elaeocarpum Reissek (Rhamnaceae) seeds
Provedor de dados: 1
Autores: Silva, Lílian Abadia da; Sales, Juliana de Fátima; Oliveira, João Almir; Pinho, Édila Vilela de Resende Von; Santos, Heloisa Oliveira dos; Soares, Marcos Antônio.
This study aimed to investigate the desiccation tolerance of Rhamnidium elaeocarpum Reissek seeds through physiological and biochemical alterations. Fruit were collected from the municipality of Jaupaci, Goias State, Brazil, when the water content of their seeds had a 37% wet basis (w.b.) and the seeds were subsequently kept in a drying oven with air circulation at a temperature of 35ºC until a water content was reached of 20 to 12% (w.b.). The following parameters were evaluated: germination, germination speed index, emergence, emergence speed index, electrical conductivity and respiration rate. Furthermore, the electrophoretic profile of the isoenzymes: catalase, peroxidase and esterase, the enzymatic activities of endo-β-mannanase and α-amylase and the...
