Seed dormancy in palms

Seed dormancy in palms, date palm inclusive have continued to be challenging especially when cultivating through seeds. This study evaluated different methods of breaking dormancy and seed germination rate in P. dactylifera. Using Completely Randomize Design, two varieties of P. dactylifera were treated with three treatments comprising sulphuric acid, hot water, cold water and control. Result showed that all the three treatments significantly (p < 0.05) affect the germination rate and ear...
