Pots selection multiple varieties available for production toon toon seedlings. Marked oil of Chun and black oil Tsubaki kinds of grain, plump, germination rate, is the most suitable varieties. Toon seed storage period is shorter, normal temperature conditions in the second half after germination rate began to decline. So, should be used in high purity, fresh, high net, no mildew, no pests, the germination rate of the seeds. 2. Cleaning and soaking soaking the seeds into a pocket, rub gently remove membranous wings, and screening stems, leaves and other impurities. Toon seeds should be soaked 24 hours after the fish.
