Hydrating lima bean seeds in saturated KCl at 41℃ for 3 days increased germination 26 to 30%, and decreased the mean number of days to germination by 1.2 to 1.7 days at 15℃. Hydration with KCl decreased the conductivity of the solution in which seeds were soaked and increased the respiration rate (at 15℃) of hydrated seeds. The mean number of days to germination and the GT90-10 were shortened by solid matrix priming. When Mean-Fan seeds were primed and dehydrated at 35℃, germination was reduced significantly to only 75.8%. In dual cultures, the growth of Trichoderma harzianum T22 hypha was faster than that of Rhizoctonia solani. Ping-Tong seeds were coated with T. harzianum T22 and 1% carboxymethyl cellulose, then priming the seeds. Biopriming significantly increased the survival of lima bean seedlings in peat moss medium from 85% to 98.3%.
