Immersion in hot water baths at 50 to 56 C for 5 to 30 minutes significantly increased the germination percentage of seeds of Tephrosia vogelii as compared to tapwater soaks and mechanical scarification. Immersion for 5 minutes at 54 C induced 96% germination with a minimum of seed swelling. Thiram fungicide, when added to the hot water bath, applied as a cool slurry after hot water immersion or applied as a dust to seeds cooled and dried after hot water immersion, had no deleterious effects on seed germination.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
