Drought is one of the major abiotic stressors which affects sugarcane crop during both vegetative and reproductive stages. Water stress has been shown to reduce sucrose and starch content in sugarcane culm and leaf. A reduction in sucrose content has been reported under water stressed conditions in sugarcane leaf buds [ 29 ]. Meanwhile, drought stress has also been reported to increase the lipid peroxidation levels in sugarcane leaves and reduce the antioxidant enzyme activities in the same tissue. Improvement of drought tolerance of sugarcane is important for achieving the goals of the Decade of Sustainable Agricultural Systems (2011-2030) in Vietnam. Sugarcane cultivars that are tolerant to drought stress will not only help in reducing the dependence of farmers on irrigation water but also provide greater food security in the long term, increase the likelihood of a warmer, wetter future climate for the region, and help to address the water stress concerns of millions of people in the Mekong Delta. Several studies have been performed for development of new sugarcane cultivars with improved drought tolerance. The studies include assessment of physiological response to drought stress, resistance to drought stress and recovery of drought damaged plants. Meanwhile, the studies focus on the genetic control of physiological and biochemical changes in the response to drought, as well as genetic variation for drought resistance and recovery in sugarcane. The studies also include evaluation of the most important metabolic pathways involved in drought resistance.
With the development of modern technology, the production and quality of cane sugar have been improved. After treated with thickener, sugar cane is processed into raw sugar for the next generation of refining. This is another key technology for sugar production and sugar refining.
While Sugarcane grown in the United States, Canada and Latin American countries is a by product from ethanol manufacture, it may never reach a level where it is that valuable or that cost effective to utilize the byproduct. For example, in Canada, the ratio of ethanol to sugar produced is 36%. In the US it is about 54%. Why make so much ethanol if you have a resource that is not cost effective to use or sell?
Great Article, Hi, can you please let me know if you have any additional data / graphs from you study that may be useful for inclusion in our publication? We are hoping to include some of your recent work on soil organic carbon contents of sugarcane soils. Best, Ola
Utilization of corn stover has the potential of producing a valuable byproduct in addition to the use of corn stover as feedstock for the production of ethanol. In some instances, it may also be converted to paper. Large ethanol producers that have started utilizing corn stover include Dow Chemical Company, BP, American Independent Oil Co., Valero, Abengoa Bioenergia, The Coca Cola Co., ICL, and The NutraSweet Co. Nalcor, a division of the Newfoundland and Labrador government, has taken a leadership role in converting a waste byproduct of the paper industry into ethanol. The basic premise is to utilize the energy-rich and moisture-rich fiber material left over from the papermaking process and add carbon monoxide and biomass to make ethanol. The chemistry of producing ethanol from these feedstocks is similar to the process employed in generating ethanol from grains. However, the large amount of residual nutrients still present in the stover makes this material relatively nutrient-poor compared to corn grain. To make ethanol economically from stover, the fiber must be converted to fermentable sugars and then to ethanol. Postfermentation by-products in stover are readily available for use as animal feed.
