In Taiwan， about 83% of the certified organic farms experience seed。saving activities. Bur in organic rice producers only 18% grew their own。seedlings in their farm， those purchased from outside only 36% acquired。organic rice seedlings. Those purchased seeds of other field crops from。outside only 25% acquired organic seeds. In organic vegetable production，。31% farms grew their own seeds， 12% got seeds from other organic farm.。There were 57% organic vegetable producers acquired seeds from seed。companies， none of them were organic seeds. Forty-eight percent organic。farmers were satisfied with current organic regulations on seeds。requirements. Twenty-three percent organic farmers favoured regulations。that designate the use of organic seeds. Only 6% of seed/seedling。suppliers sold organic seeds/seedlings； 41% suppliers received enquires of organic seeds domestically， 17% received enquires from abroad. None of the investigated seed producers produced organic seeds. As high as 65% seed/seedling suppliers interested in joining a organic seeds database.By using the rate of 100:0， 25:75， 75:25， 0:100 kaolinite and maifan stone， talc and bentonite coated on the rape seed. The germination rate of pure kaolinite and maifan stone were 98% on top paper， 93% on sand，and 96% on field emerge germination method， which were not significant different with other treatment. In average germination day， the noncoated treatment were significant lower then other treatment， 1.0 day. In the coated seeds， coated with pure kaolinite were 1.7day. The Cruciferae。seed coated with perlite powder and added functional materials on coated treatment， the germination rate were not significant different with chitosan and bamboo bio-carbon powder except broccoli added bamboo biocarbon powder by using the top paper. There were not significant different on rape seedling that coating added with functional materials.。The fresh weight， dry weight， stem length and stem diameter increased in Chinese cabbage seedling that coating added with trichoderma， Bacillus thuringiensis， chitosan. The cabbage seedling that coated treatment were higher then without coated. The fresh weight increase significant on added Bacillus thuringiensis.， and tea seed pomace. The Cruciferae coated with functional materials were not significant difference on black rot.。In this experiment， the coated addition were all commercial production. In the future， we will try to change the concentration of addition to decrease the germination effect. In the Solanaceae coating material， the kaolinite and maifan stone mix ratio 50:50 and SA liquid were suitable for tomato and hot pepper. Base on this formula， we will try to add some functional materials to increase the organic coated seed function for organic culture in the future.。
