This study was aimed at investigating the effect of crude oil concentrations on the vascular bundle sizes of two Zea mays varieties-Oba Super Zaria (OSZM) and SMZ 37 Kaduna commonly cultivated in the Southeastern Nigeria. The study was conducted in the green house in the State. The experiment was setup as a 2 × 4 factorial laid out in a Completely Randomized Design replicated three times with four treatment concentrations (0-control, 15, 30 and 45 ml) of petroleum crude and two maize varieties. Highly significant effects (P < 0.001) of the concentrations as well as the varieties were observed on the vascular bundles. The results showed a significant (P < 0.05) decrease in vascular bundle sizes with increasing concentration, with plants exposed to 45ml crude oil concentration having the smallest vascular bundle sizes. The vascular bundle sizes of Oba super Zaria decreased significantly (p < 0.05) with increasing concentrations of crude oil, while significant Original Research Article Ajuziogu et al.; IJPSS, 30(5): 1-6, 2019; Article no.IJPSS.52689 2 differences were also observed with the increasing concentrations in SMZ 37 Kaduna as compared to the control. Based on the results obtained from this investigation, OSZM appeared to be more susceptible to soils affected with crude oil.

Methods: Seeds of pepper were exposed to varying doses of gamma rays 60 Co (50, 100, 150, and 200Gy), X-ray doses (40, 60, 80, and 100KV) and sodium azide (0.01, 0.02, 0.03 and 0.04%). The treated seeds and the controls were grown in the Botanic Garden of the University of Nigeria, Nsukka using a Completely Randomized Design. Results: The result showed that vitamin C and β-carotene ranged from 5.89-26.88 and 2.62-11.35 mg/100 g, Fe and Ca (14.70 and 13.78 mg/100 g) were highest in Shombo at 100Gy. Values ranging from 0.36-2.00 and 3.96-18.82 mg/100 g were recorded for flavonoid and alkaloid content across all treatment combinations. The result also revealed that at 100Kv and 150Gy, ash Original Research Article Abu et al.; ARRB, 33(2): 1-13, 2019; Article no.ARRB.51702 2 content increased in both varieties. The highest protein concentration of 9.57% was recorded at 100Kv of X-ray in Shombo and 6.96% at 150Gy of gamma irradiation in Tatase variety. Principal component analysis explained extracted five principal axis which accounted for the variability of 72.54%. Conclusion: This study reveals that biochemical content in pepper could be improved with exposure to mutagens especially gamma irradiation.
