Description |
Viability and vigour are seed quality parameters that affect the seed chain. Seed vigour is a measure of accumulated damage in seed as viability declines from physiological maturity. This study aimed at determining the seed vigour of various sorghum genotypes stored ex situ for 10 years using the Heat Shock Stress Test (HSST), Cold Test (CT), Standard Germination Test (SGT) and field germination. The samples from the regeneration trial were kept in ex situ storage at 0-4°C and 40% relative humidity from 2003 to 2014. The experiments were arranged in a completely randomised design with four replication and differences in radicle length, shoot length for the 65 genotypes evaluated at 5% level of significance. An unpaired T- test was used to compare the accuracy of the quality methods in predicting field emergence. All the evaluated genotypes responded differentially to all the vigour test methods. There were significant differences (P |
