      More Details Abstract Fulltext PDF

      The seeds ofDuabanga sonneratioides Ham. were found to be positively photoblastic and gave fast and maximum germination of 80% in cortinuous light but failed to germinate in the dork. Longer photoperiod favoured germination. Total length of exposure to light rather than the dark period determined the germination of the seeds. Higher temperature favoured germination at a given light exposure treatment. In the field, seeds up to a depth of 2 mm in the soil could germinate. These results have been related to the light demanding nature of this carly suceessional tree species.
