ABSTRACT

To study effect of stand type and tree sizes on gum arabic yield of Acacia senegal tree species, two locations of
local villages in Sudan, called Demokeya a reserved research testing site east Elobeid town and Al-Rahad natural
open forest had been selected inside gum arabic belt. Two sizes (base on stem diameter at breath height of the
trees) were determined within these two forests. A combination of four variables was considered as source of
variation to be tested for gum yield and seeds production. Every experimental level was represented with (5 trees).
Seeds and gum arabic yield were collected from these combination groups separately, seeds were measured and
gum was weighed. The data obtained subjected to statistical analysis using (SAS) a computer software program.
The result showed a highly significant differences on fruits width and length (p = 0.001) and significant different
on seed/fruits (p = 0.05). Variation within the number of seeds per pods and the variation within the number of
seeds per pods of Acacia senegal revealed that trees of Demokeya size-2 (6-10 cm) showed highest significant
difference in number of seeds per pod (5.2 seed/fruit). The result also showed significant differences at significant
level (P = 0.01) on gum yield for size class, in the both sites, size class (2) was higher gum yield all around fifth
pickings for Demokeya and Al-Rahad areas.
