Abstract/Contents:"The purpose of this study was to find methods to promote the germination of hard seeds of Lotus corniculatus var. japonicus, a species used to create amenity grasslands. Seeds of L. corniculatus var. japonicus were round or wrinkled, and many of the round seeds were hard. Scarification with emery paper helped to make round seeds permeable, but it increased the numbers of rotted seeds or abnormal seedlings and had little effect on germination. Dry storage in moisture-proof plastic containers with silica gel at 3[degrees]C increased the percentage of round seeds that germinated, but dry storage at higher temperatures and non-dry storage at room temperature increased the percentage of hard seeds. Chilling at 3C with seeds put between moist gauze did not increase the percentage of round seeds that germinated. Of all methods tried, soaking in sulphuric acid (36 N) for 10 min increased the germination percentage of round seeds most. Seeds soaked in sulphuric acid still had a high germination percentage 12 months later. Scanning electron micrographs showed that wrinkled seeds had cracked surfaces, but that round seeds were uncracked. Soaking in sulphuric acid caused cracking of the coat of round seeds."
