| Popis: | The stand establishment of miscanthus and switchgrass is not yet mastered. However, there are few references on the factors affecting this stage. Soil temperature and water potential have a major influence on the establishment of most crops, particularly on the physiological process leading to germination and seedling growth. A controlled experiment was carried out to quantify the effects of water potential and temperature on miscanthus emergence and switchgrass germination. The calculated base temperature was 8.4°C and 8.5°C, respectively for miscanthus emergence and Switchgrass germination. Temperatures lower than 10°C decreased the germination rate of switchgrass by 50 % on average and no effect was noticed on miscanthus. The base water potential was -1.3MPa and -0.74MPa respectively for the emergence of miscanthus the germination of switchgrass. Water potential of 0.13MPa or -0.4MPa decreased respectively the germination rate of switchgrass by 10% and 40% on average and no effect was observed on Miscanthus.
