Kyushu, Japan, the objective of this study was to determine the most suitable
genotype of napier grass for dry matter production and quality (fiber content)
for biomass ethanol conversion in the year the plants were established. Six
genotypes of napier grass, a dwarf early-heading type, a dwarf late-heading
type, a hybrid of pearl millet with napier grass, a purple-foliage type and
normal varieties of Merkeron and Wruk wona, were examined for growth attributes,
dry matter yield, chemical composition and in vitro Dry Matter Digestibility
(IVDMD) at the University of Miyazaki in southern Kyushu, Japan in 2009. Dry
matter yield ranged from 13.4 to 33.5 Mg ha-1, with the highest yielder
being normal Wruk wona, followed by Merkeron. Hemicellulose and cellulose content
of both Leaf Blade (LB) and stem inclusive of leaf sheath (ST) did not differ
significantly among genotypes, except for cellulose content in ST which was
significantly higher for the dwarf early-heading type than for the other genotypes.
The dwarf late-heading type had significantly higher IVDMD in ST (65.8%) due
to lower acid detergent lignin and cellulose content in ST than the other genotypes.
Based on dry matter production, fiber (carbohydrate) content in the current
study and theoretical conversion efficiency from cellulose and hemicelluloses
of 0.29 and 0.23, respectively, Merkeron appears the most promising genotype
for biomass production, with theoretical ethanol production potential of 5850
L ha-1 year-1 in the year of establishment.]]>Anderson, W.F., B.S. Dien, S.K. Brandon and J.D. Peterson,20081451321Anderson, W.F., B.S. Dien, H.J.G. Jung, K.P. Vogel and P.J.
