ABSTRACT
The Germination and Early Seedlings
Growth Rates of Nauclea diderichii, Detarium macrocarpum, Khaya ivorensis and
Piper guineense was carried out at Michael Okpara University of Agriculture,
Umudike, Department of Forestry And Environmental Management. Identification of
trees bearing Nauclea diderichii, Detarium macrocarpum, Khaya ivorensis and
Piper guineense fruits, fruits collection, processing, cultivation and
determination of germination rates were carried out. 20 fruits were collected
from each plant and were processed separately. The viability of the seeds was
tested using the floatation method. Viable seeds were broadcasted in
germination box and later transplanted to polybags after germination. Watering
was done every morning and evening. The number of seeds that germinated was
recorded every week. The germination rates and early seedling growth rates were
determined and it showed that Nauclea diderichii and Detarium macrocarpum had
the same germination rates of 75% while Piper guineense and Khaya ivorensis
showed the lowest germination rates of 55%. The plants heights were taken on
weekly intervals and properly documented. A meter rule graded with centimeters
(cm) was used for height measurement from the root collar to the end of the
terminal bud. The leaves on the plant were counted and recorded on weekly
basis. Khaya ivorensis (29.91) had the highest mean in week six followed by
Nauclea diderichii (25.54) and Detarium macrocarpum (25.85) which had
approximately the same mean while Piper guineense (23.09) had the lowest mean
number of leaves. For mean of leaves, Detarium macrocarpum had the highest mean
(73.85) in the sixth week and Piper guineense had the lowest mean (23.62).
However, mean was also calculated for Nauclea diderichii (36.31) and Khaya
ivorensis (34.55) respectively. Piper guineense germinated earlier than other
species.
