A thermochromic indicator includes a coating on the substrate. The coating comprising a solid crystalline particles having a melting point of 0-130&#xb0; C. At temperatures below the melting point, the coating is opaque. At temperatures above the melting point, the coating becomes translucent. The change in opacity can be reversible or irreversible.

A new vigor test is used to select seeds which, after appropriate polymeric coating, will perform well under adverse planting and growing conditions. For example, suitably coated hybrid corn seeds can be planted earlier than seeds now available, while still obtaining comparable or better yields. Particularly good results are obtained when seeds are coated with compositions comprising a side chain crystalline polymer and an amorphous polymer.
