The central role of temperature in regulating plant growth was investigated by analysing the temperature sensitivity of various aspects of growth in grass leaves. A study of thermal responses in the C4 grass Miscanthus found significant genotypic variation in the effect of temperature on shoot emergence, leaf extension and seedling survival. One genotype, Sin-H9, exhibited low temperature sensitivity in leaf extension rate and shoot emergence rate. Shoots of Sin-H9 also had the highest frost tolerance, which was associated with significantly lower shoot moisture content in this genotype. The reduced time to emergence and increased frost tolerance seen in Sin-H9 was incorporated into a model of Miscanthus productivity using climate data from northern Europe. The longer growing season was predicted to increase yields by up to 26 %.
