Selecting seeds with high vigour eminently affects initial plant growth and determines stand. Various tests including electrical conductivity (EC), radicle emergence counts (RE), standard germination (SG) were used to assess the of eleven lentils (Lens culinaris L.) seed lots. Lentil lots over 75% normal germination, germinated use an ISTA test. The (2 mm) was tallied at constant intervals from...

The seed accelerated ageing test is one of the most important tests for testing vigour, which provides determination degree preservation germination and duration storage. aim this study was to observe effects two different production methods (organic conventional) on vigour soybean cultivar Kaca, by application test. seeds were exposed stress conditions 72 h (temperature 45?C air humidity 100%)...

In May, 1999 James Greig Arthur, University Professor at the University of Toronto was awarded the Canada Gold Medal by the National Science and Engineering Research Council. This is a high honour for a Canadian scientist, instituted in 1991 and awarded annually, but not previously to a mathematician, and the choice of Arthur, although certainly a recognition of his great merits, is also a reco...

A pioneer of ageing research, August Weismann has established two rather opposing concepts for aging and even today both gather numerous followers. One is the adaptive concept, according to which ageing has evolved to cleanse the population from old, nonreproductive consumers. The other, non-adaptive concept suggests that ageing is due to greater weight on early survival / reproduction rather t...
