Abstract

Abstract: The effects of different moisture content on viability and vigor of tomato seeds were studied. At the MC of 4. 6 % and 2. 4 % , there was no injury to tomato seed after 13 years storage at 20 ℃, it did not vary
significantly either in seed viability or seed vigor , the activities of dehydrogenase and SOD also remained well , electric conductivity value indicated that the membrane system of this treatment had good integrity , while at 1. 9 % moisture content , all those indexes decreased significantly. Those ultra2dried tomato seeds remained relatively high seed viability and vigor after 13 years storage at 0 ℃. The results indicated that we can store germplasm of tomato by using suitable ultradry storage.

Key words: Tomato, Seed, Ultra2dry, Storage, Viability, Vigor
