Jur. 2012The objective of this research is to observe the ability of some concentrations of fruit extract of noni in controlling seed borne fungal pathogens on red chili seeds to seed germination. The study has been conducted at the Laboratory of Plant Disease, Plant Breeding of Agriculture Faculty, Organic Laboratory of Mathematics and Sciences Faculty University of Riau from March to September 2012. The research was designed in Completed Random Design consisting of four treatments and five replications. The treatment were; without fruit extract of noni (M0), 10% concentration of fruit extract (M1), 20% concentration of fruit extract (M2), 30% concentration of fruit extract (M3). The parameters observed was percentage growth inhibition of fungus seed borne, percentage infection of fungi on seeds, percentage of seed germination on stencil paper and on topsoil. The data is analyzed by using the Analysis of Variance (ANOVA) and Duncan’s New Multiple Range Test (DNMRT) at level 5%. The result indicated that the application of fruit extract of noni depended on the applied of concentration, the higher the applied concentration, the more depressive on the seed borne fungus. The highest extract concentration (30%) gave the highest controlling effect on growth of seed borne fungal pathogens colony and the lower percentage of seed borne fungal pathogens infection, the highest controlling effect on percentage of chili seeds germination on stencil paper the application of concentration of fruit extract of noni wasn’t able to increase the percentage of chili seeds germination on topsoil.otherchili seedsfruit extract of noniseed borne fungiseed viabilitystudent Paper Post Degree
