|Abstract: ||A study was carried out in the Botanical Garden of the Department of Plant Science and Technology, University
of Jos, Nigeria, to determine the most effective method of breaking seed dormancy in Date palm (Phoenix
dactylifera L.). The treatments comprised two types of seed (fresh; seeds less than six month old and the dry
seeds were more than six months old) with four different methods of breaking seed dormancy (seeds soaked in
acid for 5 minutes, 5 minutes in boiling water, 24 hours in cold water and mechanical scarification) and the
control (seeds were not treated). The experiment was laid out in a completely randomized design and each
treatment was replicated five times. Germination rate (%) was measured weekly for four weeks and seedling
height (cm) was measured at 2 weeks interval (beginning from 35 days after planting) for a period of eight weeks.
The results showed that the different methods of breaking seed dormancy enhanced the germination of the Date
palm and seedling growth. The boiling and cold water treatments had significantly (P<0.005) higher germination
rate of 100% at 42 days after planting than the control which had 86.67%. The dry seeds had a significantly
(P<0.05) low (26.67) germination rate at 35 days after planting but, did not differ significantly with the fresh
seeds at 35 DAP. The boiling water treatment also had a significantly (P<0.005) high seedling height (25.00 cm)
at 77 days after planting. The control had the lowest seedling height of 6.72 cm at 35 days after planting. The
seeds treated with acids for 5 minutes, did not germinate at all. The result indicates that optimum germination
and seedling establishment in Date palms occurred in fresh seeds and the most effective method of breaking the
dormancy is through the use of boiling water.|
