Abstract
Pericopsis angolensis species survival is
reported to be low in nurseries. Given the
high dormancy tendency of Legume family,
it is speculated that, pre-sowing treatment of
Perocopsis angolensis seeds may result in
improved germinability. Different attempts
of breaking the dormancy to enhance
germination have been done. However, the
difference in environmental conditions - soil
pH, temperature, and water availability -
which parental plants experienced during
their growth and seed maturation, have an
impact on seed germination patterns. This
study assessed the effects of pretreatments
(soaking in cold and boiling water at
different time intervals) on the germination
of Pericopsis angolensis seeds collected in
Tabora, Tanzania. Analysis of Variance
(ANOVA) was done to show differences in
seed germination parameters under different
pretreatments. Results show that, there was
significant
(P<0.001)
difference
in
germination parameters between the control
and pretreated seeds except for the Mean
Germination Time (P>0.05). The highest
Germination Value, Germination Percent
and Germination Capacity were found under
control. The findings prove that pretreating
Pericopsis angolensis seeds by soaking in
cold and hot water have no additional effect
on germination. Thus, the study suggests that
the restoration of the forests using Pericopsis angolensis species can be achieved even
without seed pretreatments.
