Effect of hydration treatments on seed parameters of different lettuce (Lactuca sativa L.) seed lots

Research on new seed treatment methods reflects seed producers’ efforts to satisfy seed users’ enhanced requirements for seed quality. Hydration treatments are presented in literature as a possibility of improvement of seed parameters, especially of an increase in germination percentage, faster and more uniform emergence and germination under a broader range of environmental conditions (COPELAND, MCDONALD 1995). Some seed companies already use these methods as a special seed treatment in practice. The principle of hydration treatments is based on the fact that it is possible to hydrate seeds in some ways at
