Abstract
Effects of seed pre-treatments on germination of Ceiba petandra (Kapok) tree in Northern Savanna of Nigeria were studied, using Kaduna State as a case study. Three (3) pre-treatments methods (concentrated Sulphuric acid (H2S04) scarification, cold water and mechanical scarification) were used in Complete Randomized Design (CRD) experiments. The seeds were soaked in water for the period ranging between 1-7 days; those soaked in conc. Sulphuric acid were for the period ranging from 5minutes to 35minutes, while mechanical scarification ranged from 5-35 minutes. The data collected were analyzed using ANOVA and then subjected to Duncan Multiple Range Test (DMRT). The results revealed that treatment with cold water immersion for 2days gives 95% germination while treatment for 6days and 7 days are significantly (P<0.05) lower in germination, 45% and 30% respectively. Acid scarification shows that the treatment with conc. H2SO4 for 20 minutes resulted in 85% germination while treatment for 5 minutes and 10 minutes were significantly (P<0.05) lower with germination of 41% and 45% respectively. However, for mechanical scarification the result shows that germination percentage improved with increased period of shaken. Germination of seeds shook for 25 minutes, 30 minutes and 35 minutes were the highest and were not significantly (P<0.05) different from each other (80%, 71% and 68%). It is therefore, recommended that, for uniform germination and improvement of growth of Ceiba petandra the nursery workers should make use of cold water immersion by soaking the seeds in it for 2days.
