    Comparative Studies of Physico-biochemical Parameters in Abelmoschus esculentus (L.) Moench and A. moschatus (Moench)
    (2006) Adelusi, A. A.; Makinde, A. M.; Folorunso, A. E.
    Morphological features and nutritional composition were investigated in Abelmoschus esculentus (L.) Moench and A. moschatus (Moench). The seedlings, raised naturally on the field in sandy loam soil were analysed for height, length of petiole, length and breadth of leaves, number of leaves per plant, number of buds and the fruits produced. Proximate analysis was also carried out to determine the chemical composition of the leaves as well as the fruits. The two okra species share similar attributes. Number of buds were positively correlated with fruit yield in A. esculentus. The basal portions of the fruit of both species are rich in carbohydrates and fibers. The leaves are rich in fats and crude protein.

    Comparative Study of Leaf Architectural and Epidermal Features in Some Nigerian Species of Bombacaceae
    (2009) Folorunso, A. E.; Jayeola, A. A.; Olaleye-Otunla, O. J.
    Foliar architectural and epidermal studies were conducted on some species in the family Bombacaceae in search of taxonomic and diagnostic characters that could be employed for their classification and identification. Lamina symmetry, leaf form, leaf apex, leaf base, leaf margin, leaf texture, petiole, venation pattern and areolation were studied as the architectural features. Diagnostic architectural characters that distinguish Ceiba pentandra from Bombax species are acute leaf base, pinnate camptodromous venation and veinlets branching three times. Using leaf epidermal characters, the presence of wavy anticlinal wall and cuticular striations delimit Ceiba pentandra from Bombax species. Elliptic leaf form, decurrent leaf base, toothed margin, normal petiole, primary vein size stout 2-4%, veinlets branched twice, well developed and oriented areolation are diagnostic to Adansonia digitate based on the leaf architectural features and the presence of stellate trichome and large stomatal size are the epidermal characters that delimit A. digitata from all the other species in Bombacaceae. Diagnostic features of Bombax species are reported and similarly, the taxonomic characters for all the species in Bombacaceae are symmetrical lamina, coriaceous leaf texture, variation in angle of divergence nearly uniform, epidermal cell polygonal to irregular in shape and hypostomatic stomata. Taxonomic key was conducted based on the characters studied.

    Comparative Study of Protein Profiles of the Leaves of Wild Manihot glaziovii Mueller and the Cultivated Species, Manihot esculenta Crantz by SDS-polyacrylamide Gel Electrophoresis
    (2006) Folorunso, A. E.; Awelewa, O. A.; Adewale, I. O
    Polyacrylamide gel electrophoresis was conducted on leaf protein extracts of Manihot esculenta and the wild relative, Manihot glaziovii, Manihot esculenta recorded the highest number of protein bands which might be form the past hybridizational processes which had taken place between it and the wild relatives, among which is Manihot glaziovii in order to further increase the protein content of the edible Manihot esculenta, the two protein bands between 5.0 and 5.9 cm characteristic of Manihot glaziovii, as revealed in the rod gels, by electrophoresis, could be transferred to Manihot esculenta through hybridization. It is also possible that in he process, resistance to insects, diseases and drought may be transferred.

    Comparative Study on the Biochemical Properties of the Fruits of Some Annona Species and Their Leaf Architectural Study
    (2007) Folorunso, A. E.; Modupe, O. V.
    Leaf architectural and biochemical study of four species of Annona found in Nigeria and characterized as important under-utilized species was conducted in search of intrageneric characters which may be of taxonomic value in the classification of the genus. Lamina balance, leaf form, leaf apex, leaf based, leaf margin, leaf texture were studied as the architectural features. Proximate analysis of mature and ripe fruits was also carried out to determine the nutritional status of the fruits. More intrageneric relationships among the Annonas have been reported along with characters of taxonomic value in the identification and classification of the genus. A reticulata and A. squamosa appear to have better nutritional (protein) and shelf life.

    Crude Protein Electrophoresis of Some Species of Annona in Nigeria
    (2006) Folorunso, A. E.; Olorode, O.
    Seeds of four species of Annona were collected from different latitudes and special ecological zones such as the wet forest, dry forest and derived savanna areas of Nigeria and the crude proteins were extracted and analysed by electrophoretic fractionation. The result shows that the band at 3.3 cm, 4.2cm and 4.7cm are common to the Annona species. Annona squamosa and A. reticulata have the highest number of common bands. The band at 1.4cm is common to both A. reticulata and A. muricata. The number and combination of protein bands were taxon-specific. These show the close genetic relationship of the species.

    Effect of Different Drying Times on the Proximate Composition of Hydrated Soybean
    (2005) Famurewa, J. A. V.; Folorunso, A. E.
    This study investigated the relationship between the drying time and the nutrient content of hydrated soybean during drying in the process of converting it into flour. Boiling and oven drying method was used to prepare ten samples from lbadan-2000 1485 - ID at different drying times, ranging from 30 minutes to 5hrs. The results of the study showed that the protein, fat, ash and fibre contents decreased with increasing drying times while carbohydrate increased. The range was 55.02 to 4 1 .71% for protein; 24.03 to1 8.91% for fat; 8.04 to 6.03% for Ash: 8.07 to 6.03% for fibre and 4.56 to 27.31% for carbohydrate at drying times of 30 and 300 minutes respectively for all. A strong negative linear and quadratic relationship was observed between protein, fat, ash and fibre contents and drying time. The results show that drying for a long period to achieve safe moisture content; will defeat the purpose of using soy flour as supplement due to a significant reduction in the protein content. Controlled drying conditions for a short period as being investigated is therefore recommended.

    Electrophoresis of Crude Protein of Seeds of Some Genera of Annonaceae
    (2002) Folorunso, A. E.; Olorode, O.
    Seeds of five genera of Annonaceae were collected from different latitudes and special ecological zones of Nigeria, the crude proteins were extracted and analysed by electrophoretic fractionation with a view to establishing whether they have evolutionary relationships and also to know the highest protein richness in them. 0.5ml of each protein sample was loaded into the gel tubes. A current of 1.5m A per gel was applied until stacking. The current was increased to 3m A per gel. The electrophoresis was allowed to run until the dye front was about 1cm from the bottom of the gel. The result shows that the band at 5.2cm is common among the genera except in Dennettia tripetala. Intergeneric bands were observed between pairs of genera in the family. The highest intergeneric band is between Greenwayodenron suaveolens and Xylopia aethiopica at 0.2cm, 5cm and 5.1. The presence of common bands among the genera of Annonacea shows evidence of common evolutionary origin in them.

    Electrophoretic Study of Crude Protein Diversity in the Seeds of Abelmoschus Esculentus (L) Moench and a Moschatus Moench
    (2004) Adelusi, A. A.; Makinde, A. M.; Folorunso, A. E.
    Seeds of two species of Abelmoschus were collected from the National Horticultural Research Institute (NIHORT), Ibadan. The crude proteins were extracted and analysed by electrophoretic fractionation. The species of the genus have three common bands. This shows the close genetic relationship of the species and evidence of a common evolutionary origin. Also the band at 3.5cm is specific to A. moschatus and could be useful in delimiting the two species.

    Karyotype Studies in Some Species Of the Family Annonaceae
    (2007) Folorunso, A. E.; Olorode, O.
    Seeds of various accessions of Annona muricata, Greenwayodendron suaveolens and Cleistopholis patens were collected from the wet forest, dry forest and derived savanna areas of Nigeria to determine their karyotype. Each of the species has a chromosome number of n = 7 (2n = 14). A pair of satellited chromosomes was observed in the genome of Greenwayodendron suaveolens and Cleistopholis patens. The centromeric positions in the species of Annonaceae investigated are nearly median with predominance of large chromosome types. The karyotypes were similar within the species studied, with small intra-and inter-generic variations in terms of size. The karyotypic patterns suggest that there is no evidence of chromosome rearrangement in their evolution.

    Use of Fruits and Infructescense Characters in the Identification of the Acacia Mill. (Leguminosae) Species in Nigeria
    (2010) Jayeola, A. A.; Folorunso, A. E.
    Fruits and infructescence characters of 31 Acacia Mill, taxa are described in this study. Three species, Acacia auriculiformis A. Cum.ex Benth. A. auricularis A. Cunn. ex. Benth. and A. schweinfurthii Brenan. & Exell., represent new records for Nigeria while three taxa, denoted as Acacia species unidentified A, Acacia species unidentifed B. Acacia unidentified C cannot be determined reliably using the available flora and resources of the herbarium. Mophometric variants were observed in A. gourinaensis A. Chev., A. sieberiana and A. dudgeoni, with the morphs identified temporarily as A. gourinaensis A. Chev. variant a and A. gourinaensis A. Chev. variant c, A sieberiana DC var. villosa A. Chev. variant a and A. dudgeoni Gaib. ex Hall variant a, respectively. What is not known from this study, however, is if the variation is genecological or not. Presence or absence of trichomes on the fruits and peduncle; fissure, vein and constriction patterns all provided stable characters. Migrations arising from nomadic culture may have accounted for the new additions to the flora. A taxonomic key based on the characters of the fruits and infructenscences is included.
