    Effects of plant growth regulators on callus, shoot and root formation in fluted pumpkin (telfaira occidentalis)
    (Academic Journals, 2007-02) Balogun, M. O.; Akande, S. R.; Ogunbodede, B. A.
    Root and stem explants of fluted pumpkin were cultured in medium containing different types and concentrations of plant growth regulators (PGRs). The explants were observed for callus, root and shoot formation parameters after four months. Differences among explants, plant growth regulators and their interaction were not significant for number of roots per plantlet. Callus formation was higher in stem than root explants. Stem explants formed more callus in medium containing naphthalene acetic acid than that containing indole acetic acid while the trend was opposite with root explants. Root explants did not form shoots, leaves or nodes in any of the PGR regimes, while a concentration of 1.5 mg/l benzylaminopurine (BAP) induced the highest numbers of shoots, nodes and leaves per stem explant. There was no callus, shoot, node and leaf formation by both explants when cultured in medium without PGRs while root formation was minimal.

    Sex differences in biochemical contents of telfaira occidentalis hook F.
    (WFL Publishers, 2006) Ajibade, S. R.; Balogun, M. O.; Afolabi, O. O.; Kupolati, M. D.
    In order to evolve ways of early sex identification in Telfairia, the biochemical contents of leaf, vine and root of male and female plants were determined in three genotypes. Female plants had significantly higher concentrations of protein and fat while the male plant was higher in fibre, as hand all the anti-nutrients. The concentration of trypsin inhibitor was most influential in distinguishing between the sexes especially for root and vines while the fibre content was most important for the leaf. Leaf fibre content is therefore recommended for sex identification since it can be easily determined at any stage of plant development without destroying the whole plant.

    Chemical analysis and nutritional assessment of fluted pumpkin (Telfairiaoccidentalis Hook F.) seed residuefed to African catfish (clariasgariepinus) at graded inclusion levels
    (2013) Ajayi, I. A.; Olaifa, F. E.; Olawole, A. A.; Adeyemo, A. J.
    The chemical analysis and nutritional assessment of fluted pumpkin seed residue fed to African catfish (Clariasgariepinus) at graded inclusion levels was carried out in order to evaluate its effect on the growth performance and nutrient utilization of the catfish. Five diets containing 0, 15, 30, 45 and 60% inclusion levels of fluted pumpkin seed residue (FPSR) as partial replacement for groundnut cake were prepared and fed to the fishes for eight weeks. Each treatment had three replicates with 15 fish per replicate (mean initial weight 140.87 ± 8.77g) in 30-litre plastic tanks and fish fed at 3% of body weight twice daily. Fish on control diet showed the best growth and nutrient utilization while diets with defatted fluted pumpkin seeds cake produced weight reduction in the fish with the least reduction on diet 2 (15% inclusion) and greatest on diet 4 (45% inclusion). The specific growth rate, feed conversion ratios and protein intake of the control fish were significantly (p<0.05) higher than those on FPSR-containing diets.Histopathological reports showed some damage to the liver of fish in higher FPSR-containing rations, torn gill tissues and changes of intestinal structure. Haematological parameters like haemoglobin, erythrocyte, sedimentation rate and biochemical parameters were within the ranges for healthy fish though reduced from pre-treatment values
