    Abstract: This Study using purified tomato fruit chromoplasts has shown significant rates of oxygen consumption even in the absence of external precursors. Oxygen consumption rates increased up to 7-fold when chromoplast samples were incubated for 24 h at room temperature. This increase in oxygen consumption is most likely due to the activation of lipoxygena... Show More

    Abstract: Fertilizers application is required in order to improve rice production in low fertile soils of West Africa. This practice can also increase weed pressure in rice field, thereby reducing yield significantly. Chemotropism of weed was hypothesized to identify nutrient effects on weed abundance and biomass production as well as rice yield for suitable... Show More
