ABSTRACT
Seeds stocked in a swampy soil
and hevea brariliensis plantation soil of Umudike were assessed by counting and
recording the seedlings that germinated from soil monoliths collected from the
sites at different months. On the first of each month, Four soil monoliths were
taken from the swampy soil of which Two soil monoliths were taken from the
depth 0-10cm and the remaining Two from 10-20cm depth. The same method was used
in collecting Four soil monoliths from hevea brasiliensis plantation soil. The
study lasted from November 2003 to February 2004. The effect of light and depth
were investigated on the seeds stocked in the soil for 16 weeks. The design was
by randomized completely block design and analysed with analysis of variance.
From 0-10cm depth and kept in open, a total of I 8 species comprising 2489(97%)
individuals germinated from swamp soil and a total of 14 species comprising
116(3%) germinated from Hevea brasiliensis plantation soil. From 10- 20cm depth
in open, a total of 12 species comprising 926(98%) individuals germinated from
swamp soil while 10 species comprising 20(2%) individual germinated from Hevea
brasiliensis plantation soil. In the shade, a total of 7 species comprising
151(77%) individuals germinated from swamp soil while 9 species comprising
45(23%) individuals germinated from hevea brasiliensis plantation soil from the
0-l0cm.From 10-20cm depth, 6 species comprising 113(88%) individuals germinated
from swamp soil while 4 species comprising 15(12%) individuals germinated from
hevea brasiliensis plantation soil. Seed germination started within the first seven
days of collection and germination stopped after seventy days. High seed
germination from soil in the open is due to unfiltered red wavelength radiation
that reaches the soil monolith. The greater germination from swampy soil is due
to annual seed production of the grasses. Neither pioneer nor climax tree
species germinated from the swampy soil but pioneer species germinated from the hevea brasiliensis plantation soil. Climax tree species should be introduced,
as they were absent both in swampy soil and Hevea brasliensis plantation soil.
Enrichment planting of desirable economic tree species is recommended.
