“…Anderson et al (1994) observed that only 3% of maize seedlings grown at 4°C for 10 d survived, which is consistent with our observations that all maize seedlings grown at 1°C for 11 d died. Consistent with our results, prior studies of young Miscanthus shoots grown from rhizomes have reported survival from -5°C to -10°C (Farrell et al, 2006;Zub et al, 2012), though in both of these studies the belowground portions of the plants were purposely protected from the cold treatment.

Miscanthus is a genus of perennial, warm season grasses that is a leading candidate for biomass production in temperate environments. Relative to other C4 grasses, some Miscanthus genotypes have exceptionally efficient photosynthesis at low temperatures. Typically planted at about the same time as maize (Zea mays L.), it is unknown if earlier planting of Miscanthus would be possible or even preferable. Moreover, little is known about the response of Miscanthus to frosts. The aim of this study was to determine low temperature thresholds for damage and death of Miscanthus seedlings in a controlled environment chamber, quantify the effect of early planting dates for Miscanthus seedlings in the field on survival, growth, and yield, and assess genotypic differences for spring and autumn frost tolerance for field plantings of established clonal materials. We observed that Miscanthus seedlings and mature plants had exceptional cold tolerance for a C4 grass. In a controlled environment chamber, 29 to 65% of seedlings in four Miscanthus populations subjected to a 12 h cold treatment at −10°C survived, whereas none of the maize seedlings survived a 1°C treatment. In the field, all Miscanthus seedling populations tested had ≥66% survival in 2011 and 2012, despite light freezes associated with planting in mid‐March at Urbana, IL. The standard for biomass production, M. ×giganteus J. M. Greef & Deuter ex Hodk. & Renvoize, had low frost tolerance relative to other genotypes, indicating potential for genetic improvement.

“…A thorough comparison of the field performance and the physiological and growth response to chilling temperatures was carried out using one M. × giganteus clone and one M. sinensis Goliath clone. M. × giganteus was chosen because it is the most planted and studied Miscanthus genotype, while M. sinensis Goliath has been included in several field trials (Robson et al 2011, Van Hulle et al 2012, Zub et al 2012a, Larsen et al 2013 and physiological studies (Clifton-Brown and Jones 1997, Vargas et al 2002, Zub et al 2012b, Domon et al 2013, Purdy et al 2013). Similar to a report from Denmark (Larsen et al 2013), M. × giganteus was consistently higher yielding than M. sinensis Goliath in a field trial established in Melle, Belgium in 2007 (Muylle et al 2015).…”

A long growing season, mediated by the ability to grow at low temperatures early in the season, can result in higher yields in biomass of crop Miscanthus. In this paper, the chilling tolerance of two highly productive Miscanthus genotypes, the widely planted Miscanthus x giganteus and the Miscanthus sinensis genotype 'Goliath', was studied. Measurements in the field as well as under controlled conditions were combined with the main purpose to create basic comparison tools in order to investigate chilling tolerance in Miscanthus in relation to its field performance. Under field conditions, M. x giganteus was higher yielding and had a faster growth rate early in the growing season. Correspondingly, M. x giganteus displayed a less drastic reduction of the leaf elongation rate and of net photosynthesis under continuous chilling stress conditions in the growth chamber. This was accompanied by higher photochemical quenching and lower nonphotochemical quenching in M. x giganteus than that in M. sinensis 'Goliath' when exposed to chilling temperatures. No evidence of impaired stomatal conductance or increased use of alternative electron sinks was observed under chilling stress. Soluble sugar content markedly increased in both genotypes when grown at 12A degrees C compared to 20A degrees C. The concentration of raffinose showed the largest relative increase at 12A degrees C, possibly serving as a protection against chilling stress. Overall, both genotypes showed high chilling tolerance for C-4 plants, but M. x giganteus performed better than M. sinensis 'Goliath'. This was not due to its capacity to resume growth earlier in the season but rather due to a higher growth rate and higher photosynthetic efficiency at low temperatures

“…However, Miscanthus × giganteus has a narrow genetic diversity [16] and is not adapted to all climatic zones [40,41]. It is crucial that the genetic diversity of the Miscanthus genus is investigated to determine if varieties suited to a broader range of environments can be developed.…”
