| Abstract | ||
| Heat stress due to increased temperature is an agricultural problem in many areas in the world. The objective of this study was to examine changes in seed germination characters, cell membrane stability, lipid peroxidation level and electrolyte leakage in germinated seeds exposed to heat stress. Seed germination, co-efficient of germination and germination vigor index asignificant decreased (due to high temperature) is compared to control (untreated seeds). The MDA a signficant increased, whereas the protein content asignficant decreased due to high temprature. Heat stress a signficant increased proline content. Electrolytes level (as indicator on perturbation of membrane permeability) a signficant increased with exposure period increase to high temperature. | ||
