Cultivated at two different sowing dates at Green house of chungnam Rural Development administration from 1990 to 1995. Days to emergence of Lactuca at the delayed sowing of 30th May was promoted by four day than that of the early sowing of 15th Feburary. At the early sowing Ratio of emergency was appeared to be high than that of the delayed and Ratio of germination of Lactuca at $25^{\circ}C$ showed to be high as 89% especially, germination and growing and fresh weight were high at natural water soaking treatment than convential method. Length of leaf of Lactuca treated at Ga 50 and 100ppm was higher as 12 to 16cm than 36cm of check and fresh weight was also high as 21-56% than check in test of table guality fresh leaf of Lactuca was appered to be same favorite as perilla leaf, lettuce especially the usage of Lactuca grown about two to three weeks was appeared to be good.
