Pre-sowing seed treatment of sorghum for germination at stress conditions

Abstract Sorghum (Sorghum bicolor L. moench) is one of the most important food grain. But in the Czech republic is sorghum only alternative crop. It is an interesting alternative instead of maize not only like a food crop, but for feed animals and an energetic use. Germination of some seeds is inhibited various of factors, for one thing time of ripe, for one thing existence various inhibitors etc. For that reason is an effort adjust some seeds before sowing suitable methods. Seed hydratation is usualy method seed treatment before sowing in last years on many varietes of crops. Seed hydratation is perform like a methods for improvement seed properties of seed of sowing, primary for faster germination and growth and at the same time reduct minimal temperature for germination , sensitiveness to water stress and absence an oxygen at germination. The thesis deals with seed germination of sorghum (Sorghum bicolor (L.) Moench) in adverse (stress) conditions this time in water stress conditions. The aim of this thesis was to asses possibilites of influencing germination seed of sorghum (Sorghum bicolor (L.) Moench) in stress conditions. on rudimentthis research there were rate genotypes, they are resistance drought at germination. At the same time was review the best method of seed hydratations for better ressistance to drough at germination. For practise it was foun, that using this test it is possible to test germination in earlier conditions and determine based on find, which varietes is cultivate in this conditions
