ABSTRACT
Flowering and fruiting periodicities,
seed germination, proximate composition and phytochernical contents of edible
fruits/seeds of seven woody plant species of the Nigerian rainforest were
studied at the Michael Okpara University of Agriculture, Umudike, Nigeria from
1st January. 2007 to 30th September, 2007. The seven species were: Canariurn
schweinfurt Dacryodes eduiis, Dennetia iripetala, Hevea hrasiiiensis,
Parkia biglobosa, j?icinus conirnunis and Uvaria charnae. Hevea brasiliensis
had bimodal flowering periodicity (January — March) while the other six plant
species had unimodal flowering periods. ('anariwn schweinfurihii (February —
March and June July) and I-f. brazil/ens/s (April June and September — October)
had bimodal fruiting periods. The other five plant species had unimodal
fruiting periods. The statistically equal seed germination percentages (100%)
of D. edulis, H. brasiliensis, R. conimunis and U chaniae were significantly higher
than those of G. schweinfurt h/i, P. biglobosa and D. iripetala. Hevea
brasiliensis had hypogeal germination while the other six species had epigeal
germination. Pcirkia biglobosa had significantly the highest moisture contents
(MC) while 1). tripe/ala and (I chuinac with statistically similar MC gave the
least results. Uvaria chamac and P. cc/u/is had the highest and least (P 0.05)
dry matter (DM) contents. Uvaria charnae and D. edulis gave significantly the
highest and least ash contents. C'anariurn schweinfurthii and D. edulis had the
highest and least (P < 0.50) crude protein (CP) contents respectively
Dacryodes edulis and D. tripe/ala gave significantly the highest and least
ether extracts (EF) respectively. C'anariurn schweinfurthii and R. communis had
respectively, the highest and least crude fibre (CF) contents. Ut'ariu channie
and I). edielis gave significantly the highest and least carbohydrate (CHO)
contents respectively. I-fe yea bras/liens/s and P. h iglohosa had
significantly the highest and flavonoid contents respectively. Ricinus
conimunis and D. edulis respectively gave the highest and least (P < 0.05)
phytate contents. Hevea brash/ens/s had significantly the highest alkaloid
content while D. edulis and P. biglobosa, with statistically similar values,
gave the least (P < 0.05) alkaloid contents. Uvaria chaniae and D. cc/u/is
had significantly the highest and least P contents respectively. Ricinus
communis and D. edulis gave respectively the highest and least (P < 0.05) K
contents. Dennelia tripe/ala had significantly the highest Na content while P.
biglohosa and H. hras'iliensi,s with statistically similar Na contents, gave
the least (P < 0.05) results. Denneiia tripelala had significantly the
highest Ca and Mg contents while C'. schweinfurthii and H. bras/liens/s gave
respectively the least Ca and Mg contents.
