This study was conducted to find the methods of disinfection and hastening of the germination for black locust seeds. The results obtained were as follows : 1. Colletotrichum sp., Fusarium spp. Cladosporium sp. and bacterial etc. were isolated from the seeds.Colletotrichum sp. and Fusarium spp. were not only adherent to the surface of seeds, but also dormant in the tissues of seeds. The seeds and seedlings were attacked by these organisms, and consequently the germinating percentage was decreased.2. Pouring of boiling water upon the seeds was most effective to hastening the germination of hard seeds of black locust, and soaking of the seeds for 5 minutes in 70℃ water was also effective.The results of these seed treatments were not satisfactory to seed disinfection.Seed disinfections with Ceresan and Uspulun were very effective, especially the dusting with Ceresan showed continual effect.The combination of the hot water treatments and the seed disinfection with Ceresan had good effects upon the germination of the seeds. The dusting of the wet seeds with Ceresan, after soaking in hot water, injured the germination, and seed surface keeping dry is necessary to avoid the fungicidal injury.
