Brown Mid-rib and Photoperiod-Sensitive Forage Sorghums
نویسنده
چکیده
Hay and silage crops are integral parts of beef production in the Great Plains. In the southern Great Plains, a growing dairy industry is adding demand for silage and hay. Corn silage has long served the region well, producing consistent high quality silage. However, many areas of the southern Great Plains no longer have the irrigation capacity to successfully produce corn silage. Forage sorghums are a viable alternative crop under these conditions. They can be planted later than corn, use water more efficiently and hence still produce acceptable silage yields when planting is delayed, irrigation capacity is limited or droughtier growing conditions.

Brown Midrib Forage Sorghum, Sudangrass, and Corn: What Is the Potential?
Brown midrib, a genetic mutation in several grassy species, reduces lignin content in the total plant parts. Lignin is mostly indigestible but also plays an important role in plant rigidity. During the past several years the brown midrib (bmr) trait has been incorporated into forage sorghum, sudangrass, and corn. The results have been significant for the most part. IVTD values for bmr sorghum h...
متن کاملUtilizing the Bmr Trait in Sudangrass and Sorghums
Brown midrib (BMR) is a genetic mutation in several grass species. The BMR gene reduces lignin content in plant cell walls and vascular tissue and improves fiber and whole plant digestibility. Lignin is mostly indigestible and plays a critical role in forage quality by affecting digestibility of cell wall polysaccharides. Lignin also plays in important role in plant rigidity. During the past se...
متن کاملEvaluation and characterization of forage Sorghum as feedstock for fermentable sugar production.
Sorghum is a tropical grass grown primarily in semiarid and drier parts of the world, especially areas too dry for corn. Sorghum production also leaves about 58 million tons of by-products composed mainly of cellulose, hemicellulose, and lignin. The low lignin content of some forage sorghums such as brown midrib makes them more digestible for ethanol production. Successful use of biomass for bi...
