“…Similar features were also reported by Odeigah et al [7] with oilfield wastewater, Ogbemudia et al [34] with whole and water saturated fractions of hydrocarbons, Nwakanma et al [36] with diesel and gasoline, Olayinka and Arinde [37] with spent engine oil, Iyaba and Offor [22] and Osawaru et al [23] with crude oil. Oil-polluted environment also affects the chlorophyll contents of plants.…”

“…This can simply mean the quantitative and qualitative analyses of plant extracts; it involves the extraction, isolation, identification and characterization of extracts from parts (leaves, stem, flowers, fruits, roots) of a photosynthetic plant. Physico-chemical analyses are usually carried out before and after pollution occurs, results are then compared to evaluate the presence of substances that were not present before the occurrence of pollution; they are known to be reliable environmental bioindicators [9,23,31,32].…”

This paper reviews the mechanistic and genetic effects of spilt crude oil and associated drill site chemicals on some Nigerian plants. Methods that range from morphological and physical observations, physico-chemical, anatomical, cuticular to cytological and cytogenetic analyses were reviewed. Quality data on various negative consequences of exposure of plants to pollution and contamination by crude oil-related pollutants were x-rayed. Proper legislation, monitoring and enforcement of sound environmental Laws by stakeholders were advised. Government collaboration with research institutions in order to keep abreast with new research findings was suggested as a way to help strengthen, manage and reinforce environmental Laws in order to protect our sources of food.

The genus Corchorus includes nutrient rich indigenous leafy vegetables often grown or harvested in the wild in Africa. It has potential to contribute to food security, but there is need to improve it as a crop through plant breeding. However, not much is known about the genetic variability among Corchorus species. The aim of this study was thus to characterise the available germplasm of Corchorus accessions and investigate heritability of their agro-morphological traits. Materials and methods: Eleven Corchorus accessions (4 South African and 7 from the World Vegetable Center) were evaluated in a field study at Roodeplaat, South Africa, for their morphoagronomic traits using a randomised complete block design with three replications across two seasons (2015/2016 and 2016/2017). Data were subjected to ANOVA, principal component analysis and cluster analysis. Broad sense heritability, genetic advance, genetic parameters and correlations were determined among the accessions and traits. 1 Results and conclusions: The Corchorus accessions showed significant (P<0.05) differences in all the quantitative traits evaluated. The data showed significant variability among the studied Corchorus accessions in their agro-morphological traits for exploitation in future breeding programs that in turn can contribute to the improvement of this crop.

West African Okra (WAO) Abelmoschus caillei (A. Chev.) Stevels is common in traditional agricultural systems, where it is cultivated for its leaves, fruits, seeds, floral parts and stems. This study aims to conduct morphological evaluation of WAO fruits in order to investigate their diversity and contribute to conservation strategies. Using random stratified sampling method, WAO fruits were collected in Abudu, Ogan, Ologbo, Agenebode communities in Edo State and Koko, Agbor and Umunede communities in Delta State. Results showed that the highest mean and standard error values of pod length (cm) (10.98 ± 0.21) was recorded from Ogan and the least (7.46 ± 0.39) was obtained from Umunede. Highest mean and standard error of pod width (cm) were obtained from Ologbo (9.81 ± 0.59) while the least value was recorded from Agenebode (8.29 ± 0.43). WAO fruits collected from Ogan had the highest mean value for pod size index (10.35 ± 0.21) while the least value was recorded from Agenebode (8.10 ± 0.17). Results for number of ridges on WAO fruits suggest highest and least mean values were recorded from Ogan and Agenebode communities (8.90 ± 0.41 and 6.80 ± 0.20), respectively. The nature of fruit tip of WAO fruits collected from Abudu, Agbor, Agenebode, Ogan and Ologbo were 100% acute, Koko and Umunede are 80% acute and 20% obtuse. The fruit base of Okra from Abudu and Ogan is 100% flat. Agbor and Ologbo had 90% flat fruit base and 10% protruding fruit base. The nature of fruit base of both Agenebode and Umunede is 60% flat and 40% protruding, while that of Koko is 70% flat and 30% protruding. These results suggest morphological variations in WAO within the study area. The variation in traits may be a pointer to the differences in the genetic make-up of the accessions considered.
