Effects of polymer coating and non-coating on seed quality of cucumber, chili, eggplant and jute were studied by determining seed moisture content and imbibition. The experiment was done at seed laboratory, Department of Horticulture, Kasetsart University, Bangkhen Campus, during August 2007 to March 2008. The coated seeds kept in 20 deg C for 0 and 8 months were determined and compared the germination, germination index and mean germination time with uncoated seeds. The results showed the moisture contents of polymer coated seeds were increased, but the water imbibitions of those seeds were slower. The polymer coating decreased germination and speed of germination of chili seeds, but increased those of eggplant seeds. The speed of germination of jute seed coated with polymer was also increased. Polymer coating had no effect on germination and vigor of cucumber seeds. However, the longer storability period decreased seed quality by reducing seed germination and vigor of all species.
