摘　　要：<i>Terminalia</i><span style="font-family:;" "=""> <i><span style="font-family:Verdana;">brownii</span></i><span style="font-family:Verdana;"> is an indigenous tree species highly valued in the Kenyan drylands for its products such as timber for wood curving, medicine, and charcoal production, among others. Due to this high value followed by overutilization, its population in the drylands is dwindling. Concern about the species</span></span><span style="font-family:Verdana;">’</span><span style="font-family:Verdana;"> low regeneration as shown by low germination has been raised.

The seeds were harvested for fruit probing for maturity confirmation. Random sampling was used in selecting thirty trees, 50 meters apart, from which fresh fruits were uniformly collected from the crowns. The research adopted a complete block experimental design where one hundred seeds each from the three sites, were subjected to a germination test, seed borne fungal organisms’ presence, identified organisms cultured and DNA and DNA sequencing carried out for identification.
