Abstract
To determine lethal temperature of birdsfoot trefoil(BFT) and italian ryegrass(IRG) at heat-stressed conditions, seedlings grown in a small pots fur 4 weeks were subjected to different temperature regimes of heat treatment. No apparent damage was observed BFT and IRG were treated at 45, 50 or $60^{\circ}C$ for 1 h. And also heat treatments at 60, 65 and $70^{\circ}C$ for 1 h, both of them were withered and showed damage symptom on their leaves but it was not lethal conditions for the whole plants. By contrast, most of plants were prominently withered within one day after heat treatment at $80^{\circ}C/60min$. When BFT was exposed to $80^{\circ}C/60$ min, they were died within 6 days but there was found that new shoots were regenerated from the plants that had been treated at $80^{\circ}C$ within 55 min. IRC was also died within 2 days that exposed to $80^{\circ}C/20$ min but there was found that new shoots were regenerated from the plants that had been treated at $80^{\circ}C$ within 15 min. These results indicate that heat killing temperatures of BFT and IRG plants are $80^{\circ}C/60$ min an $80^{\circ}C/20$ min respectively. Simple viability assay system established in this study will be useful for selection and characterization of heat-tolerant transgenic BFT and IRG plants.
