This investigation was undertaken under the shade at the Nursery of Antoniades Botanical Garden, Hort. Res. Inst., Alexandria, Egypt during 2014 and 2015 seasons to study the effect of the following pregermination treatments: untreated intact fruits (as control), depulped seeds (Pyrenes) without any treatment, soaking the depulped seeds in tap water for either 24 or 48 hours, soaking the depulped seeds in hot water (60-70 °C) for 24 hours or soaking them in diluted sulphuric acid (50 %) for either 6 or 12 hours on germination characters of Pygmy date palm (Phoenix roebelenii O`Brien) seeds and growth and quality of the resulted seedlings.The obtained results indicated that soaking the depulped seeds in tap water for 24 h. treatment gave the highest percentage of germination in the two seasons and followed in the first season by soaking in hot water for 24 h treatment, but in the second one by the untreated depulped seeds. The depulped seeds soaked in diluted H2SO4 (50 %) for 6 h. failed to germinate in both seasons, while those soaked in such acid for 12 h. gave 10 % germination only in the first season. The least number of days passed to either the highest percent of germination (G.V.) or 50 % germination (MGR) in the two seasons was also recorded by soaking in tap water for 24 h. treatment. The germination rate index (GRI) was significantly increased over control by depulping and soaking in tap water for 48 h. treatments, but slightly decreased by soaking in tap water for 24 h. and significantly by soaking in hot water for 24 h. treatments compared to control in the two seasons. Most of the used treatments improved the means of vigour index (V.I.), seed viability (S.V.), plumule length, vegetative and root growth parameters of the produced seedling, as well as their leaf content of pigments and total soluble sugars with various significant differences relative to control means in most cases of both seasons. However, the mastership was recorded for treatment of soaking in tap water for 24 h., which gave the utmost highest values in most of the previous measurements in the two seasons.So, it can be recommended to soak the depulped seeds (Pyrenes) of Pygmy date palm (Phoenix roebelenii O`Brien) in tap water for 24 h. to achive the highest and fastest germination along with the best quality of the seedlings.
