Summary

Effect of cumin seed exudates on spore germination of Curvularia lunata, Alternaria solani and Colletotrichum capsici was studied in the laboratory. Three-hour exudate obtained for first 3-hour favoured initial protrusion but inhibited subsequent growth of the germ tubes. Two-hour exudate obtained between 5 and 7 hours after soaking was suggested to have no effect on initial protrusion but was found to have promotive effect on subsequent growth of germ tube. Short treatment with inhibitor for 45 minutes followed by a treatment with promotor ensured high germination and uniform germ tube growth. Modifying effects on the spermatosphere and adaptive significance of sequential exudation are discussed. re]19730125
