1 Faculty member, Agricultural and Natural Resources Research Center of Yazd, Iran ABSTRACT. Seed aging is the main problem of seed storage. Changes of enzyme activity and reduction of seedling growth are consequence of seed deterioration. An experiment was conducted to evaluate the effects of accelerated aging on germination indexes and enzyme activity of barley seeds. Seeds were incubated in ...

ABSTRACT- This experiment was carried out during the growing seasons of 2010 and 2011 at the Agricultural Research Farm of Bu-Ali Sina University, to study the effect of weed competition on subsequent germination and seed vigour of chickpea. 12 weed interference durations were evaluated in a randomized complete block design with three replications. Experiments consisted of two sets of treatment...

study of magnetic field and seed hydropriming effects on tomato seed germination was done in laboratory of ferdowsi university of mashhad, iran. the experiment was as factorial experiment based on randomized completely design, which was including two level of hydropriming (use of dry seed and soaked seed in distilled water for five hours) and eight level of magnetic field (pretreatment of seeds...

The results of present investigation revealed that among the different potting media treatments, M1: Vermiculite + Garden soil Sand was found to be most beneficial for improving took days germination, germination percentage, height seedling, number leaves seedling-1, stem diameter, primary roots length (cm), secondary roots, fresh and dry shoots weight, seed vigor index – I II leaf area (cm). I...

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%)...
