Effect of packaging material on the ripening of mature plantain
(Faculty of Science, University of Ibadan, 2011) Aduramigba-Modupe, A. O.; Olaniyi, O; Oyetoran, B. O.
Freshly harvested mature plantain (Musa spp. AAB-group) bunches from the field were evaluated in the laboratory to assess the effect of packaging material on its ripening. The bunches were separated into hands and hands one to three were employed in the study. The fruits were subjected to three treatment conditions: (1) exposed on laboratory bench without any packaging, (2) packed in thin black nylon fastened bags, and (3) packed in thick black polythene fastened bags. The set up was arranged in a 3 x 3 factorial randomized complete block design with hand number and packaging materials forming the factors. Response of the fruits was monitored over a period of eighteen days, determined by the number of ripe fruits (i.e. fingers) per hand. At the end of the first week, there was no significant difference in fruit ripening rate while in the second week, the exposed plantain fruits ripened faster than the packaged ones. However, ripening rate for fruits packed in thin polythene bags was significantly higher (P< 0.05) than the unpackaged control and fruits packed in the thick polythene bag. Fruits stored in the thick polythene bags had longer shelf life in the green state, ripened more uniformly and is recommended for commercial bulk processors who would require large quantities of fruits in either the green state or ripened states.
Antimicrobial Activities of crude ethanolic extract of Xylopia aethiopica
(International Journal of Current Research (IJCR), 2011) Oloyede, A. M.; Aduramigba-Modupe, A. O.
Crude ethanolic extract of Xylopia aethiopica traditionally used as condiment in food and against bacterial infections, cough and inflammations was evaluated invitro for its antimicrobial activities against Escherichia coli, Salmonella typhi, Bacillus aurum, Staphylococcus aureus, Bacillus subtilis and a fungus pathogen Candida albicans, so as to justify its medicinal activities and validate its traditional use scientifically. The agar diffusion technique was used to determine the zone of inhibition and the minimal inhibitory concentration (MIC) respectively. The extract was active against E. coli, S. typhi, Candida albicans, B. aurium with 15mg/ml MIC, though was most active against S .typhi and B. aurum and compared favourably and significantly with ampicillin. X. aethiopica did not show any activity against S. aureus and B. subtilis. This study has provided relevant scientific information for the potential use of X. aethiopica for antimicrobial activities. It therefore suggests that X. aethiopica contain a broad spectrum antibiotic compound, which if properly harnessed can be used in managing an array of pathogens
Distribution of yam anthracnose disease in Nigeria
(International Society for Tropical Root Crops-African Branch, 2010) Aduramigba-Modupe, A. O.; Odebode, A. C; Asiedu, R.
Yam anthracnose disease, characterized by leaf necrosis and shoot die-back, is a major constraint to the cultivation of yam, especially water yam (Dioscorea alata Linn.). Studies were conducted on the distribution of the disease in the major yam growing zones in Nigeria. Yam anthracnose disease was found to be widely distributed in 148 farmers' fields in three agroecologies. The incidence was 52.2% in the southern Guinea savanna, 51.3% in the forest/savanna transition, and 40.3% in the humid forest, with D. alata having the highest severity score followed by D. rotundata. Colletotrichum gloeosporioides (Penz) was the pathogen most commonly associated with the symptoms of anthracnose based on isolations from leaf samples collected from the farmers' fields. Fusarium spp., Rhizotonia solani (Kuhn), Botryodiplodia theobromae (Pat), and Macrophomina phaseolina (Tassi) were also isolated from the infected yam leaves.
