Annual Sainfoin (Onobrychis crista-galli (L.) Lam.) is widely adapted to moderate and cold regions of Iran and naturally grows in pasture and rangelands used for forage in these areas. In order to study the effects of priming on seed germination and seedling growth in O. crista-galli, two factorial experiments were conducted based on a randomized complete design with three replications under la...

Temperature and relative humidity in combination cause rapid decline in seed quality during storage. To maintain the seed quality in storage a number of physical and chemical treatments are used. Magnetic field treatment is one such physical treatment practiced to improve the seed quality. An experiment was conducted to investigate the efficacy of this treatment to improve the storability of se...

Seed ageing during storage is one of the main causes of reduction in seed quality and this results in loss of vigour and failure to thrive. Finding appropriate storage conditions to ameliorate deterioration due to ageing is, therefore, essential. Ultrastructural changes in cellular organelles during storage and seed germination rates are valuable indices of damage that occurs during seed ageing...

Seed ageing is influenced by two environmental factors, RH and temperature. The deterioration of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. Accelerated ageing has been recognized as a good predictor of the storability of seed lots. Aged seeds show decreased vigour and produce weak seedlings that are unable to survive once re...
