“…Potassium and holo-cellulose contents (sum of a-cellulose plus hemicellulose) (25,79,80) were positive in correlation, but the other components were indifferent. Of the3e indifferent components, lignin (12,58) which has been considered to be related to the breaking strength of the culm, was included. Of other components there were silica (25,58,80), starch (64,83), sugar (79,80) etc.…”

“…As a result of these studies it became clear that there are some morphologically distinctive characters between the culm of the lodging and the non-lodging plants (8,9,20,25,60,66,79,80,82,83). Also, it was made clear that lodging is related to cultural conditions, such as soil fertility (40,46), methods of fertilizers supply (11,12,21,40,46,54,58,67,69), varieties (2,18,26,49,53), sowing quantities (9,21,26,43,72) and the depth of irrigated water (1,34,63,68,69). It was also discovered that lodging occurred in some years but not in others when the same cultural method was continued (45,48,69,80).…”

“…Dadswell and Hawley (17) reported that brash specimens of Douglas fir contained a higher lignin and lower cellulose content than tough wood specimens. A low carbohydrate-nitrogen ratio (118, 119) has been associated with lodging resistance, but conflicting results have been reported for ash content (19,87,102).…”

Modern biotechnology has the potential to substantially advance the feasibility, structure, and effi ciency of future biofuel supply chains. Advances might be direct or indirect. A direct advance would be improving the effi ciency of biochemical conversion processes and feedstock production. Direct advances in processing may involve developing improved enzymes and bacteria to convert lignocellulosic feedstocks to ethanol. Progress in feedstock production could include enhancing crop yields via genetic modifi cation or the selection of specifi c natural variants and breeds. Other direct results of biotechnology might increase the production of fungible biofuels and bioproducts, which would impact the supply chain. Indirect advances might include modifi cations to dedicated bioenergy crops that enable them to grow on marginal lands rather than land needed for food production. This study assesses the feasibility and advantages of near-future (10-year) biotechnological developments for a US biomass-based supply chain for bioenergy production. We assume a simplifi ed supply chain of feedstock, logistics and land use, conversion, and products and utilization. The primary focus is how likely developments in feedstock production and conversion technologies will impact bioenergy and biofuels in the USA; a secondary focus is other innovative uses of biotechnologies in the energy arenas. The assessment addresses near-term biofuels based on starch, sugar, and cellulosic feedstocks and considers some longer-term options, such as oil-crop and algal technologies. Also critical to bioenergy, but only indirectly infl uenced by biotechnology, are policy and economics issues. For example, the Renewable Fuel Standard (RFS) and other government policies directly support the biofuels industry, and uncertainty about their stability directly infl uences bioenergy investment. Consistent policies are essential for near-term deployment because they aff ect whether developers can obtain funding for fi rst-generation biorefi neries. Policies regarding uses of genetically modifi ed organisms (GMOs) also will have a direct bearing on biotechnology implementation. Use of GMOs within the confi nes of a biorefi nery is generally accepted if biocontainment is practiced; however, the use of GMO plants and algae is a matter of debate worldwide. Public acceptance of GMO plants in the USA depends on their being regulated and thoroughly studied. Th ese restrictions can add years to fi eld testing and eventual deployment; however, biotechnological advances can speed the regulatory processes. Algal feedstock developers presume their GMOs will be closely contained in closed photobioreactors.
