英文摘要	The present study was carried out in the Egyptian Deserts Gene Bank (EDGB), North Sinai Research Station, Desert Research Center, Egypt, during the period of 2005 to 2008. The aim of this study was to investigate the seed viability of Balanites aegyptiaca (L.) Del. Under different storage conditions (room temperature, +4 degrees C and -22 degrees C) and various storage periods (fresh seeds (control), 6 months, 12 months and 5 years "seeds were stored up to 5 years ago in Egyptian Deserts Gene Bank"). Different breaking dormancy treatments were used to encourage, germination of Balanites aegyptiaca (L.) Del seeds. The results showed significant effects for conservation conditions, storage periods and dormancy breaking treatments on seed viability parameters. Germination percentage was the highest when seeds were stored under +4 degrees C for six months and when treated by dry heat at 60 degrees C for 15 minutes to break dormancy. The fresh seeds (control, the seeds new collected) gave the highest viability percentage. The seeds, which stored at -22 degrees C gave the highest value of all germination parameters when were stored for 12 months. The increase in germination parameters were greatest for seeds treated with 60 degrees C for 15 min. This significantly denotes the seeds requirement for high temperature to achieve greater viability after storage.
