    Effects of Allelochemical of Jatrophacurcas L. Leachate on Germination and Rooting of Four (4) Pepper (Capsicum) Species

    A study was carried out on the effect of allelochemicals of Jatrophacurcas L. on germination and rooting of four pepper species (Capsicum spp) in the Department of Plant Science and Biotechnology Laboratory, Nasarawa State University Keffi, Nigeria. Data was collected on percentage inhibition and shoot length. Results generatedfrom the study showed that there were significant differences among the values of treatments (4%, 8%, 12%, 16% and 20%) and the control (0%) and within the treatments at P ≤ 0.05 level of significance. Eventually all the test samples were said to be affected by various sort of range of concentrations of the aqueous extracts and the most obvious (i.e most significant) effect was at 12%, 16% and 20% concentrations of the extracts in all species respectively. Germination and early rooting were retarded (delayed) completely at higher concentrations in virtually all the cases when placed in comparison with the control sample. The inhibitory (retardation) effect was seen to be relyon concentration and may also be due to the presence of water soluble allelochemicals like phenols, tannins and azelaic acid.
